Liquid pump driving heat pipe device for cascade mechanical refrigerating and operation method

Abstract

A liquid pump driving heat pipe device for cascade mechanical refrigerating and an operation method belong to the technical field of heat exchange of heat exchange devices. The liquid pump driving heat pipe device comprises a mechanical refrigerating loop and a heat pipe cooling loop, wherein the mechanical refrigerating loop is formed by a liquid-liquid heat exchanger group, a gas-liquid separator, a compressor, a condenser group and a throttling component sequentially from end to end or is formed by a liquid-liquid heat exchanger group, a compressor, an oil separator, a condenser and a throttling component sequentially from end to end. The other path of the liquid-liquid heat exchanger group is sequentially connected with a liquid reservoir, a liquid pump, an indoor heat exchanger group and an outdoor heat exchanger group from end to end. Refrigerating is conducted by respectively or simultaneously opening the mechanical refrigerating loop and the heat pipe cooling loop. Through the device and the method, a yearly operation method mainly relying on liquid pump driving heat pipe radiating and supplemented by mechanical refrigerating is achieved fast and conveniently, mechanical refrigerating and heat pipe cooling of a system are ensured to operate simultaneously, required electricity consumption is greatly reduced, and use rate of natural cold sources is greatly improved.

Description

technical field [0001] The invention relates to a liquid pump-driven heat pipe device and an operation method for cascade mechanical refrigeration, and belongs to the technical field of heat exchange of heat exchange equipment. Background technique [0002] In data centers or communication equipment rooms, due to the long continuous operation time of IT and communication equipment and the large heat generation, special cooling equipment is required to dissipate the heat of equipment or components to the outdoor atmosphere to maintain the ambient temperature in the equipment room and ensure that the equipment normal operation. At present, the more common practice is to use air-conditioning equipment to remove the heat from the working environment in the computer room to achieve the purpose of cooling down. However, the operation of air-conditioning equipment consumes a lot of energy and the operating cost of the system is relatively high. In order to reduce the energy consum...
