Multi-evaporator loop heat pipe

Abstract

The invention discloses a multi-evaporator loop heat pipe. The structure comprises a condenser, gas-liquid pipelines and four evaporator compensator units, the design method that four evaporators share one condenser is adopted, and the evaporators are gas-coupled. The condenser comprises a steam cavity, a converging hole cover plate and a condensing distributing plate; by the aid of the structurallayered design of the condenser, the evaporators are symmetrically distributed in the circumferential direction of the condenser, the design of pipelines are matched with the condenser, superheated steam is coupled in the steam cavity at the upper layer of the condenser, enters the lower-layer condensing distributing plate via converging holes for condensing heat exchange and flows out evenly along dispersing flow channels. Evaporator compensators adopt the integrated design of cylindrical structures. By the aid of the loop heat pipe, the design of an efficient heat transfer component under the condition that the single cold source faces multiple dispersed heat source is realized, and the heat uniformity among the evaporators is improved with the design method of gas coupling and uniformdistribution.

Description

technical field [0001] The invention relates to the field of phase change heat, in particular to a heat exchange element design based on the heat exchange principle of a loop heat pipe. Background technique [0002] With the development of space detection technology, the requirements for integration and light weight of satellite systems continue to increase, especially for applications such as large-scale infrared remote sensing detectors and wide-field ray telescopes, and the degree of integration of components on board satellites continues to increase. As the temperature rises, the power of the load is also continuously increased. In order to meet the higher detection requirements, the cooling demand of the large-area array is gradually increased, which puts forward higher requirements for the thermal control and thermal design of the load on the star. Therefore, it is necessary to simultaneously solve the problems of multi-heat source control, high heat flux dissipation, ...

Problems solved by technology

Due to the limitation of bending, this method greatly affects the integrated layout of the load system. At the same time, the shape of the evaporator is relatively simple, which does not meet the requirements of complex heat source coupling.
