To improve the heat exchange efficiency of the heat exchanger, two aspects need to be considered at this time:
1. On the premise of taking away the same amount of heat from the heat source, how to minimize the rise in the temperature of the heat exchanger itself, for example, the same amount of heat makes the temperature of heat exchanger A itself rise by 20 degrees, while the temperature of heat exchanger B is It can only rise by 5 degrees, so the advantages and disadvantages of the two heat exchangers are obvious. It can also be seen from the basic formula of heat conduction as “Q=K×A×ΔT/ΔL”, only when the temperature rise rate of the heat exchanger itself slows down, can the temperature difference between the heat source and the heat exchanger be maintained, so as to ultimately ensure the thermal conductivity. effectiveness. This aspect mainly involves the specific heat of the heat exchanger material.
2. How to strengthen the heat exchange capacity between the heat exchanger and the external environment and drive the heat away from the heat exchanger. The technology in this area covers a wide range. For example, air cooling takes the heat away from the heat exchanger by forced convection, while Passive heat exchange is often a huge heat exchange area for heat exchange with air, and so on.
