Sintering device and method capable of quantitatively controlling porosity parameters of capillary wick

Abstract

The invention provides a sintering device and method capable of quantitatively controlling porosity parameters of a capillary wick. The sintering device comprises a punching head, clamping blocks, elastic connecting pieces and sleeves. The lower end of the punching head is arranged on the inner sides of the sleeves. Clamping block installing grooves are formed in the lower end of the punching head. The clamping blocks are connected with the groove bottoms of the clamping block installing grooves through the elastic connecting pieces. When each elastic connecting piece is compressed through the corresponding clamping block, the corresponding clamping block is contained in the corresponding clamping block installing groove. Clamping grooves matched with the clamping blocks are formed in the inner wall faces of the sleeves. When each clamping block is contained in the corresponding clamping block installing groove, the punching head can be inserted into the sleeves, and each clamping block can enter the corresponding clamping groove under the drive of the corresponding elastic connecting piece. The sintering device and method capable of quantitatively controlling the porosity parameters of the capillary wick can be applied to loop heat pipes and other products, and capillary wicks required by specified porosity parameters can be rapidly obtained in the processes of researching, developing, testing and producing. The sintering device and method have the characteristics of being low in cost, rapid, efficient and quantitative, and application prospects are wide.

Description

technical field [0001] The invention relates to capillary cores, in particular to a sintering device and method capable of quantitatively controlling the porosity parameters of capillary cores. Background technique [0002] Loop Heat Pipe (LHP for short) is a high-efficiency heat transfer device that relies on the capillary suction of the capillary product in the evaporator to drive the circuit, and uses the phase change of the working fluid to transfer heat. It has strong heat transfer capacity and low thermal resistance. , good isothermal, high efficiency, no moving parts and long transmission distance, etc., making it an effective device for thermal control of spacecraft and heat dissipation of high heat flux electronic devices. [0003] The capillary core is the most critical component in the loop heat pipe. The capillary force generated by the capillary core is the only driving force for the fluid to circulate in the loop, and its parameters will directly affect the per...

Problems solved by technology

At present, most research institutions and units mainly determine the proportion of sintered materials and sintering parameters through experiments, and use ordinary sintering devices for sintering. The obtained capillary cores have low success rate, long cycle, large batch differences, Problems such as poor repeatability seriously restrict the localized application of loop heat pipes
