Abstract

A forced cooling device based on latent heat exchanging comprises a high-temperature evaporator, a low-temperature condenser, a throttle, a delivery pump, a liquid trap, a safety valve, a stop valve, a temperature control system and a working medium filling device which are connected through high-pressure hoses. The phase change latent heat of working media is used to take away heat, and the forced cooling device is mainly used for solving the radiation problems of large-power electronic components. The delivery pump delivers the liquid working media in the liquid trap to the evaporator, the liquid working media absorb heat and is gasified, the gaseous working media flow into the condenser, is liquefied and release heat to the environment, and liquid working media converge into the liquid trap under gravity action. The temperature control system controls the rotation speed of the delivery pump through the temperature feedback at a cold end and a hot end, and accordingly the heat exchanging power of a working medium flow control device. The safe and nontoxic R134a is used as the working media, and equipment and the environment cannot be damaged even leakage occurs.

Description

technical field [0001] The invention relates to the technical field of heat transfer and heat exchange, in particular to a forced heat exchange device based on latent heat utilization. Background technique [0002] With the development of integrated circuit technology and microelectronics technology, various small-sized, highly integrated electronic products continue to emerge. However, highly integrated circuit systems must face the problem of insufficient heat dissipation. The current heat dissipation problem has become a limitation for the development of electronic products and integrated circuits. One of the bottleneck technologies. At present, for the heat dissipation of large-scale integrated circuits such as high-performance workstations and servers on the market, there are mainly two solutions: air-cooled and water-cooled. The cooling function mainly depends on the temperature rise of air or water to remove heat. Taking the workstation mainframe as an example, the m...
