A separate heat pipe that can automatically adjust the charge distribution

Abstract

The invention discloses a separate heat pipe capable of automatically adjusting the distribution of charging amount, which relates to the technical field of heat pipes and includes: an automatic adjustment device for charging amount, a lower liquid pipe, an evaporator, a steam pipe, a condenser, an upper liquid pipe, an upper Temperature sensing package, upper pressure induction tube, lower temperature sensing package, lower pressure induction tube. Through the implementation of the present invention, using the influence of ambient temperature on the outlet subcooling degree of the separated heat pipe condenser and the evaporator outlet superheating degree, the size of the condenser outlet and the evaporator inlet are respectively controlled by the subcooling degree and the superheating degree, thereby realizing the basis The ambient temperature automatically adjusts the amount of refrigerant in the condenser and evaporator.

Description

technical field [0001] The invention relates to the field of heat pipes, in particular to a separate heat pipe capable of automatically adjusting the distribution of charging amount. Background technique [0002] Energy and chemical equipment, refrigeration and air conditioning devices, electronic cooling systems and many other industrial equipment require efficient and low-energy heat dissipation processes. As a heat dissipation device, the separated heat pipe only relies on gravity to drive the working medium to circulate among the four components of the evaporator, steam pipe, condenser and liquid pipe to dissipate heat, without the need for energy-consuming driving components such as compressors or pumps. It has the advantage of low energy consumption. The refrigerant charge amount of the existing separate heat pipe is fixed, and its value is determined according to the refrigerant amount required under the rated operating conditions. However, when the environmental co...

Problems solved by technology

The existing method of "adjusting the charging amount of the heat pipe according to the environmental conditions" cannot achieve "automatic adjustment"; the patent CN109489303A discloses a heat pump / heat pipe composite heating device with an adjustable charging amount of the working fluid, which is used in the heat pipe Increase the way of manually adjusting the valve to adjust the refrigerant charging amount, which can only be adjusted manually

The existing method of "automatically adjusting" the charge of the heat pipe cannot be "adjusted according to the ambient temperature"; patent CN111678270A discloses a heat pipe and vapor compression composite system with a self-operated capacity adjustment liquid reservoir, which is based on the heat pipe / vapor The charging amount can be automatically switched according to the different compression operation modes; the refrigerant charging amount obtained by adjusting this method is determined by the system operating mode and does not adjust with the environmental conditions
