Description

【Technical Field】 [0001] The invention relates to a detection device, in particular to a detection device for detecting the performance of a heat pipe. 【Background technique】 [0002] The basic structure of the heat pipe is to line the inner wall of the closed tube with a porous capillary structure layer that easily absorbs working fluid, and the central space is empty, and the evacuated closed tube is filled with a total of pores equivalent to the capillary structure layer. The volume of the working fluid can be divided into the evaporation section, the condensation section and the adiabatic section in between according to the relative position of the absorption and dissipation of heat. [0003] The working principle of the heat pipe is that when the evaporation section absorbs heat, the liquid phase working fluid contained in the capillary structure layer is evaporated, and the vapor pressure is increased, and the generated high enthalpy steam flow is quickly moved along the ce...

Problems solved by technology

[0007] However, the above-mentioned existing heat pipe performance detection device still has the following disadvantages: the lengths of the evaporation section 2a and the condensation section 2b are difficult to accurately control, which are important factors for evaluating the variation of heat pipe performance; Variation due to the influence of the test environment; and the close thermal contact between the heat pipe and the heat source and heat sink are not easy to effectively control and other shortcomings, which are not conducive to accurate evaluation of the performance of the heat pipe. The performance testing device is only suitable for small-scale heat pipe testing on a laboratory scale, and cannot meet the testing requirements required for mass production processes.

[0008] In order to meet the inspection requirements of the mass production process of heat pipes, it is necessary to strictly control the quality of heat pipes with a large number and various forms; because the inspection of mass-produced heat pipes of the same form requires the use of a large number of testing machines at the same time, and these testing machines Long-term and frequent repeated use is required; therefore, in addition to the measurement accuracy of the machine itself, it is necessary to strictly control the assembly variation and operation variation of a large number of testing machines; the quality of the testing device will directly affect the quality of production Yield and cost, the industry is bound to face the multiple challenges of accuracy, convenience, speed, consistency, reproducibility, and reliability during testing; in view of this, it is necessary to make significant improvements to the current heat pipe testing device, In this way, the fool-proof design of assembly and operation and the modular design of component manufacturing are incorporated together to meet the inspection requirements of the mass production process of heat pipes
