Introducing the folding fin developed by Mogami Inks. (Technical Advisor, Mr. Ohara) The pipe and piping outer wrap fin developed by our company (hereafter referred to as OPFF) has the power to increase the heat dissipation area to approximately 10 to 20 times that of the base pipe, while being retrofittable. Traditionally, finned pipes were made by welding, brazing, or extrusion to the base pipe, but these methods are difficult for bending processes and do not work with base pipes made of glass or resin. OPFF can improve heat dissipation performance regardless of the material of the base pipe, and its effectiveness has been confirmed to increase by 20% to 150% with natural convection cooling, and even more with forced convection. Features: ◎ Retro-fittable ◎ Can be wrapped around piping and pipes ◎ Made of thin metal sheets – lightweight ◎ No initial mold costs required ◎ Small lot sales available ◎ High performance *For detailed content of the column, please refer to the related links.

In this column, I will discuss research examples of surfaces that prevent frost formation. Figure 1 shows the state of condensed water on a superhydrophobic surface observed with an electron microscope. The size of the water droplets can be as large as 100 microns. It is well known that water droplets on a hydrophobic surface tend to form beads, as seen on lotus leaves. However, condensed water originates from the microscopic irregularities of the surface, causing it to grow in a root-like manner as shown in Figure 2, and it does not form beads like in Figure 1. On superhydrophobic films, while condensation does lead to the formation of water droplets, they do not freeze for more than an hour. *For more details on the column, you can view the related links.

In this column, we will discuss the issue of frost when using heat pumps for vehicle heating. As explained in the 16th column, heat pumps extract heat from the air, and the total of the extracted heat and the compression energy from the compressor is used as a heating source. When the outside air is cold, refrigerant at temperatures below minus 10°C passes through the outdoor unit, cooling the air with that refrigerant, which causes condensation, and the condensed water freezes. Over time, this begins to block the entire surface of the outdoor heat exchanger, resulting in no airflow and preventing heat exchange. In short, the heat pump stops functioning. *For more details on the column, please refer to the related links. For further inquiries, feel free to contact us.

In this column, we will discuss the cooler for cooling power modules with dual-side heat dissipation. The diagram shows an example of a heat exchanger that cools power modules with dual-side cooling, as explained in the previous column. The biggest challenge is how to cool the power module from both sides. The idea of arranging the cooling water passages in parallel and sandwiching the power module between them is good, but the challenge lies in how to ensure contact. *For more detailed information on the column, please refer to the related links.

In this column, I will discuss the cooling mechanisms of inverters. The cooling mechanisms of inverters include single-sided cooling, as shown on the left of the diagram, and double-sided cooling, as shown on the right. In the case of single-sided cooling, the semiconductor device is soldered to a substrate and then joined to a heat sink made of ceramic materials with good thermal conductivity and insulation, such as aluminum nitride, which is then cooled through a cooling channel. In this case, to cool the semiconductor substrate from one side, multiple semiconductor chips are arranged on a flat structure and cooled from one side. *For more detailed information, please refer to the related links.

In this column, we will discuss the thermal management of electric vehicles. As the reduction of carbon dioxide, a cause of global warming, becomes a significant social issue, the transition from gasoline engine vehicles to electric vehicles is expected to accelerate rapidly, and automakers are speeding up their development. Thermal management is a crucial challenge for electric vehicles. When it comes to thermal issues, the main purpose in traditional engine vehicles has been to cool the engine and engine oil, as well as to cool the air for air conditioning. However, in electric vehicles, the waste heat from the engine can no longer be used as a heat source for the air conditioning system. *For more details on this column, please refer to the related links.

In this column, we will discuss the air conditioning methods and challenges of electric vehicles. As shown in the diagram of the refrigeration cycle, the air that exchanges heat with the refrigerant in the evaporator becomes cold air, which is used for cooling in the summer. However, to achieve the preferred temperature for the occupants, it is necessary to mix this cold air with warm air generated by the heater core. The hot water entering the heater core is the cooling water from the radiator. In recent years, the popularity of hybrid vehicles has led to a shortage of this heating source. This is due to the reduced heat generation from the engine as it operates intermittently. Especially in winter, due to the lack of heating, methods such as electric heaters (PTC heaters) have been put into practical use to supplement the heating. When fully transitioning to electric vehicles, this issue will become even more pronounced. *For more details on the column, you can view it through the related links.

We received a consultation stating, "The finned piping is interfering with the surrounding equipment, and it's causing problems." As a solution, please consider "wrapping folding fins around the piping." When fins are continuously formed at a certain height like in finned pipes, it is not possible to change the height midway. However, if fins are wrapped around and installed afterward, it becomes possible to install fins of varying heights depending on the interference situation, eliminating the need for significant design changes solely aimed at avoiding interference. Since this is a retrofitting measure, it can be utilized as an option when necessary, allowing for convenient use without major changes to the design or drawings. [Case Summary] ■ Issue: Finned piping is interfering with surrounding equipment. ■ Proposed Solution: Consider wrapping folding fins around the piping. *For more details, please refer to the PDF document or feel free to contact us.

• Heat exchanger

We received an inquiry stating, 'I want to shorten the distance required for heat exchange.' As a solution, please consider 'installing folding fins on the gas side.' If the flow path on the gas side is a circular pipe, installing the fins along the outer wall of the flow path can increase the heat transfer area. When folding fins shaped like those in the diagram are installed, in addition to expanding the heat transfer area, the fluid will flow more easily near the pipe wall, which can improve the heat exchange efficiency with the external fluid side. Therefore, we believe this could contribute to the overall compactness of the heat exchanger.

In this column, I will discuss the composition of the car air conditioning refrigeration cycle and its challenges. The principle of cooling is based on a closed circuit known as the refrigeration cycle, which consists of two heat exchangers, a compressor that compresses the refrigerant, and an expansion valve that serves as a depressurization device. Recently, with the demand for improved fuel efficiency in vehicles, there has been a growing need for energy-saving measures in car air conditioning systems, leading to various considerations. The most effective method is to enhance the performance of the condenser. By improving its performance, the high pressure decreases, which reduces the compression work of the compressor, thereby leading to a reduction in the input energy of the compressor. Additionally, it is also necessary to improve the efficiency of the compressor itself. *For more details on the column, you can view it through the related links.

• Air conditioning

In this column, we will discuss the water drainage issues in car air conditioning evaporators and their solutions. The evaporator draws in warm, humid air and cools and dehumidifies it using the latent heat of refrigerant evaporation, which naturally leads to the generation of condensate. When the air conditioning is turned off, not all of the water is drained; some remains in the evaporator, with an approximate volume of 500cc. When the air conditioning is turned back on and airflow begins, this water is suddenly expelled, causing a phenomenon known as water spitting from the air conditioning vents. Numerous studies have been conducted to solve such problems, and it has now become mainstream to utilize the hydrophilicity of water to reduce the amount of retained water. *For more detailed information, please refer to the related links.

In this column, following the 8th installment, I will discuss how to protect a heat exchanger from perforation due to pitting corrosion and gas leaks for 15 years using an extremely thin aluminum tube with a thickness of 0.2mm. Metals each have their own electrochemical potential, and when different metals come into contact, the metal with the lower potential tends to corrode preferentially. For example, between zinc and iron, zinc has a relatively low potential, so it corrodes preferentially while iron remains unaffected during that time. This principle is utilized in the outer walls of ships, where a zinc coating is applied to the iron body to prevent salt damage from seawater. Similarly, galvanized steel sheets are coated with zinc to prevent the corrosion of iron, and they are widely used in buildings and structural materials. *For more details about the column, please refer to the related links.

This column introduces the topic of "Corrosion Resistance of Aluminum Sheet Materials" and heat exchangers. It discusses why aluminum sheet materials used in heat exchangers, particularly with a tube thickness of only 0.2mm, can maintain corrosion resistance for over 15 years, presented in two parts. Pitting corrosion, noted in the upper left, progresses in the thickness direction of the sheet and can lead to water leaks in the tubes or refrigerant gas leaks in a short period, making it a corrosion mode that heat exchangers must be vigilant about. One of the significant challenges for heat exchanger designers is how to prevent this. *For more details on the column, please refer to the related link.
