technical field

The utility model relates to a heat exchange module and a heat exchange device, in particular to a heat exchange module and a heat exchange device for transferring heat energy.

Background technique

A heat exchanger is a device that transfers thermal energy from one space to another. The heat transfer process is generally divided into three ways, namely conduction, convection and radiation. Generally, the heat transfer of heat exchangers often exists in three ways at the same time, but according to different occasions, one of the ways is often dominant. In industry The heat transfer of the heat exchanger used is mainly to transfer heat energy from the hot fin area to the cold fin area through conduction or heat pipes. There are both convective heat transfer and conduction heat transfer. basic theory.

An existing heat exchange module includes a heat exchanger installed above the cabinet, and fans and cooling fins are installed inside and outside the cabinet to conduct heat to the outside, but this method occupies a lot of space in the cabinet. It is also inconvenient to go up.

Another heat exchange method is to add two more fans inside and outside the cabinet to generate two airflows, and place the fans at one end of the upper radiator and the lower radiator, and blow airflow to the other end. However, due to the relationship of air resistance characteristics, when the airflow generated by the fan reaches the rear end of the upper radiator and the lower radiator, the heat conduction efficiency is reduced due to the reduction of wind pressure, and this heat exchange method also occupies the space of the cabinet. Also increased production cost simultaneously.

The heat pipe can transfer the heat energy accumulated in the first heat dissipation unit to the second heat dissipation unit, or transfer the heat energy accumulated in the second heat dissipation unit to the first heat dissipation unit.

As mentioned above, the heat exchange module and the heat exchange device provided by the utility model are provided with a fan in the opening of the heat exchange device. The hot air absorbs the heat inside the casing through the second heat dissipation unit and transfers the heat to the outside of the casing through the heat pipe.
