Vehicle-mounted mobile constant-temperature liquid cooling source device

Abstract

The invention discloses a vehicle-mounted mobile constant-temperature liquid cooling source device which comprises a cooling unit, a water cooling unit, an environmental temperature sensor and an electrical control unit, wherein the cooling unit, the water cooling unit, the environmental temperature sensor and the electrical control unit are integrated in a frame; the cooling unit, the water cooling unit and the environmental temperature sensor are all electrically connected with the electrical control unit; and the cooling unit is connected with the water cooling unit through a heat exchangerand a plate-type evaporator. By adoption of the vehicle-mounted mobile constant-temperature liquid cooling source device disclosed by the invention, the flow rate and the cooling liquid temperature can be accurately controlled; the device integration level can be improved; and the energy consumption can be lowered.

Description

technical field [0001] The invention relates to cooling technology, in particular to a vehicle-mounted mobile constant temperature liquid cold source device. Background technique [0002] Conventional vehicle-mounted electronic equipment has the problem of high heat during operation. If the heat is not taken away in time, its working performance will be affected. The common way is to use fans to cool electronic equipment naturally. This method has low air supply pressure and long cooling time. , the cooling capacity is limited, it can only meet the electronic devices with general heat generation, and the cooling effect on electronic equipment with large heat generation is not good, which will affect its normal operation. For the on-board electronic equipment with large heat generation, the cooling method currently used often adopts a separate design of refrigeration cabinets and water-cooling cabinets, which has the following problems: [0003] 1) It takes up a lot of space...

AI Technical Summary

Problems solved by technology

[0003] 1) It takes up a lot of space, the integration level is not high, and it is not easy to troubleshoot and repair;

[0004] 2) Due to the adoption of common control methods without hot gas bypass and refrigerant flow regulation technology, precise control of the coolant supply flow and supply temperature cannot be achieved, and the temperature of the output refrigerant water fluctuates greatly, and the cooled object is suddenly cold and suddenly Severe heat phenomenon;

[0005] 3) Due to the use of compressor refrigeration, when the ambient temperature is lower than 0°C, the heat of the electronic equipment can only be taken away by the compressor to maintain the operating temperature of the electronic equipment, and the natural cooling of the ambient wind cannot be effectively used, and the energy of the cooling system The consumption cannot be reduced, and there are some unfavorable factors for the service life of the compressor.
