Heat radiator with air pump separate type thermosiphon for machine room or machine cabinet

Abstract

The invention relates to a heat radiator with an air pump separate type thermosiphon for a machine room or machine cabinet, which belongs to the technical field of heat exchange of heat radiators. The heat radiator comprises an evaporator (1), a condenser (4), a liquid collecting pipe (6), a steam pipe (2), an air pump (3) and a liquid storage bend (5), wherein the condenser (4) is positioned on the upper part of the evaporator (1), the upper part of the evaporator (1) is communicated with the condenser (4) by the steam pipe (2) and the air pump (3), the bottom of the evaporator (1) is communicated with the bottom of the condenser through the liquid collecting pipe and a liquid storage bend, a seal space is formed in the hear radiator, and liquid working media are filled into the seal space. After the evaporator absorbs heat, the internal liquid working media in the seal space are gasified, steam is transmitted to the condenser by the air pump through the steam pipe, the liquid working media change into liquid after radiating heat to air around in the condenser and flow back to the evaporator through the liquid storage bend and the liquid collecting pipe, and thus, the heat radiator can radiate internal heat of a seal machine room to the atmosphere, increases the steam power of the working media and the utilization ratio of the condenser and has better heat radiating performance in a larger heat radiating range.

Description

technical field [0001] The invention relates to a heat dissipation device used in occasions requiring cooling such as a machine room or a cabinet, and belongs to the technical field of heat exchange of heat exchange equipment. Background technique [0002] In industrial computer rooms or cabinets, due to the long continuous operation of electrical equipment and large heat generation, special cooling equipment is required to dissipate the heat generated by the equipment or components to the atmosphere to maintain the ambient temperature in the computer room or cabinet and ensure the safety of the equipment. work normally. At present, the more common method is to use air-conditioning equipment to remove the heat from the working environment inside the computer room or cabinet, so as to achieve the purpose of cooling the computer room or cabinet. Although this heat dissipation and cooling method can meet the requirements of cooling and temperature control, the operation energy...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides a thermal siphon cooling device with an air pump separated for the computer room or cabinet, which aims to reduce the cooling and heat dissipation energy consumption of the computer room or cabinet and improve its internal The reliability of the equipment, prolonging the service life of the equipment, and fundamentally solving the technical problems of the insufficient kinetic energy of the working medium steam to overcome the flow resistance and the unsatisfactory heat dissipation effect in the ordinary separated heat pipe heat removal device, so that it can be used in a wide range of heat generation. Good heat dissipation performance both inside and under the condition of large heat flux
