The heat exchanger can be a forced convection type heat exchanger and a natural convection type heat exchanger according to the requirements of application scenes. Generally, a fan and other devices must be added to the forced convection heat exchanger to increase the disturbance between the heat exchange medium and the heat exchanger, so that the heat exchange efficiency of the forced convection heat exchanger is generally higher than that of a natural convection heat exchanger, but the energy consumption and noise for driving the fan are additionally increased. After the heat exchange mode of forced convection or natural convection is determined, the heat exchange efficiency of the heat exchanger is basically determined, and the difference is small in terms of improving the heat exchange efficiency. Therefore, in most cases, increasing the heat exchange area is a commonly used technical means.
