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 that the inner wall of the closed tube is lined with a porous capillary structure layer that is easy to absorb the working fluid, while the central space is in a hollow state, and the total amount of pores equivalent to the capillary structure layer is injected into the vacuumed closed tube. The volume of working fluid can be divided into evaporation section, condensation section and adiabatic section in between according to the relative position of heat absorption and dissipation. [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 evaporates, and the vapor pressure increases, and the high-enthalpy vapor flow generated is quickly moved...

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 carry out strict quality control on a large number of heat pipes in various forms; because the detection 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 need Long-term and frequent repeated use; 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 The industry is bound to face the multiple challenges of accuracy, convenience, speed, consistency, reproducibility, and reliability during detection; in view of this, it is necessary to greatly improve the current heat pipe detection device, so that Incorporate the modular design of assembly, operation and component manufacturing to meet the inspection requirements of the mass production process of heat pipes
