Problems solved by technology

[0004] The disadvantages of the existing CPL system are: ①It is difficult to start the CPL system; ②During operation, due to the instability of the vapor-liquid two-phase flow in the condenser, it is easy to cause temperature and pressure fluctuations in the system. When the working conditions change, sometimes the evaporator burns out, which leads to the failure of the operation

Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] As shown in Figure 2, the evaporator 1 is a planar capillary evaporator, and the condenser 2 is a planar capillary condenser; the steam outlet b of the evaporator 1 is connected to the steam inlet c of the condenser 2, and the liquid reservoir 3 The liquid inlet and outlet f of the condenser 2 are connected to the liquid discharge port d and the condensate outlet e of the condenser 2, and the condensate outlet e of the condenser 2 is connected to the reflux liquid inlet a of the evaporator 1 through the subcooler 4 .

[0034] When the present invention runs stably, the steam produced in the evaporator 1 enters the condenser 2 through the steam outlet b through the steam pipe and enters the condenser 2 through the steam inlet c, and returns through the liquid outlet e through the cooler 4 and the reflux liquid inlet a of the evaporator 1 after condensati...

Abstract

The present invention discloses a CPL system with plane type capillary core evaporator and condenser. Its structure is characterized by that the steam outlet of its evaporator is connected with steam inlet of its condenser, and the liquor storage device is connected with condensate outlet of condenser, the described evaporator is a plane type capillary core evaporator, and the condenser is a plane type capillary core condenser, said liquor storage device is connected with liquor-discharging outlet of condenser, and the condensate outlet of condenser is connected with return flow liquor inlet of evaporator by means of subcooler.

Description

technical field [0001] The present invention relates to a CPL system having an evaporator and a condenser. Background technique [0002] CPL (Capillary Pumped Loop: capillary pumping two-phase fluid circuit) is a phase change heat transfer device that relies on capillary pumping force to drive the circulation of working fluid. It has strong heat transfer capacity, good isothermal performance, high temperature control accuracy and low energy consumption. , Good heat sharing, and no moving parts, it is an ideal device for cooling electronic devices. The CPL system mainly relies on the liquid working fluid to absorb heat in the evaporator and the vapor-phase working medium in the condenser to release heat to achieve heat transfer. [0003] As shown in Figure 1, the existing CPL system mainly includes an evaporator, a condenser, a liquid receiver, and steam and liquid pipelines. Both the evaporator and condenser adopt a circular tube structure. The evaporator is the main part ...
