The working principle is as follows: the utility model discloses utilize density difference drive principle, heat absorption pipeline and thermal cycle pipeline all are in the box, are in the heat absorption state, so the coolant liquid temperature in it rises very fast, and outside cooling circulation pipe and the heat dissipation pipeline were in the box, are in the heat dissipation state, so the temperature rise is slower. The density will decrease after the water temperature rises, and the water temperature will descend when the water temperature is low. Therefore, driven by the density difference, the water forms a slow circulation along the path of the heat absorption pipeline (heat absorption) -heat circulation pipeline (heat absorption) -heat dissipation pipeline (heat dissipation) -cold circulation pipeline (heat dissipation) -heat absorption pipeline (density difference driving principle). The temperature in the box is continuously taken out of the outside and is dissipated, and if the temperature is higher, the efficiency of the heat dissipation fan for accelerating the heat dissipation can be started, the heat dissipation fan forms airflow in the duct, and the heat dissipation efficiency of the heat dissipation pipeline is accelerated. And the slow flow can ensure that the cooling liquid can fully absorb heat in the box body and fully dissipate heat outside the box body.
