Radiator of gravity loop heat pipe, condenser and manufacturing method thereof

Abstract

The invention discloses a condenser in a radiator of a gravity loop heat pipe and a manufacturing method thereof. The manufacturing method comprises the following steps of: extruding a condenser substrate into a condenser base plate and a plurality of parallel condenser longitudinal channels passing through the condenser base plate; drilling holes at two ends of the condenser base plate and forming condenser cross channels communicated with the condenser longitudinal channels; and plugging the end parts of the condenser longitudinal channels and the condenser cross channels according to the confirmed connecting ports communicated with the outside on the condenser. According to the manufacturing method, the condenser longitudinal channels are formed on the base plate in an extruding manner, the condenser cross channels are formed on the base plate by drilling holes, and the condenser longitudinal channels and the condenser cross channels are formed into an integrated structure and are free from being connected in a welding form, so that no welding point exists between the formed condenser longitudinal channels and condenser cross channels of the condenser, the sealing property and strength of the condenser are ensured, and the working reliability is higher. The invention also discloses the radiator of the gravity loop heat pipe and the manufacturing method thereof.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a condenser in a gravity loop heat pipe radiator and a preparation method thereof. The invention also relates to a gravity loop heat pipe radiator and a preparation method thereof. Background technique [0002] The Gravity Loop Heat Pipe Heat Sink (LTS) is a two-phase phase change heat sink. Please refer to figure 1 , figure 1 It is a schematic diagram of the working principle of a radiator in the prior art. [0003] The radiator is mainly composed of four parts: an evaporator base plate 20 , a condenser 10 , a vapor ascending pipeline 30 , and a liquid return pipeline 40 . [0004] The evaporator base plate 20 has a longitudinal pipeline 203, the lower end of the evaporator base plate 20 has a horizontal liquid converging pipeline 202, and the upper end has a horizontal vapor converging pipeline 201; the condenser 10 has a longitudinal pipeline 103, and the upper end o...
