At present, a general solution is to add a heat dissipation fan in a closed container, where the heat dissipation fan blows air to a heat generating portion of a product, heat exchange capability of the heat generating portion is enhanced by enhancing convection, heat released by the product is added and released into the closed container, and then heat exchange is generated between air in the closed container and a container wall, so as to cool air in the closed container, and the container wall then realizes heat release through heat exchange with the outside, that is, a current heat release path is: product → air in the closed container → closed container wall → ambient environment. For the heat release path, although the fan can release the heat of the product into the closed container, the heat exchange efficiency between the air in the closed container and the wall of the container is very low, which causes the temperature in the closed container to rise continuously, the temperature in the closed container in a balanced state often seriously exceeds the temperature of the product in normal operation, which causes the product not to operate normally, and the service life of the product is also greatly reduced. In addition, the conventional fan has limitations in reliability, particularly, reliability in continuous operation for a long time, and a life span, and once a failure occurs, damage to a product may be fatal.
