Description

technical field [0001] The invention relates to a detection device, in particular to a heat pipe performance detection device. 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 operating 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 the operating fluid can be divided into an evaporation section, a condensation section, and an adiabatic section in between, according to the relative position of absorbing and dissipating heat. [0003] The working principle of the heat pipe is that when the evaporation section absorbs heat, the liquid-phase operating fluid contained in the capillary structure layer evaporates, and the vapor pressure increases, and the high-enthalpy vapor flow generated is quickly moved along t...

Problems solved by technology

[0007] However, the above figure 1 and other existing heat pipe performance detection devices generally have the following shortcomings, which are not conducive to accurately evaluating the performance of heat pipes; including:

[0008](1) In order to achieve the close thermal contact between the heat pipe, the heat source and the heat sink, and to accurately measure the wall temperature of the evaporation section and the condensation section of the heat pipe at the same time, the current detection The device is difficult to balance;

[0009](2) The above requirements are more difficult to effectively control when multiple detection devices are used in mass production;

[0010](3) It is difficult to accurately control the effective length of the evaporation section and the condensation section during the rapid full inspection, which is another important factor causing the variation of the performance of the heat pipe;

[0011](4) Heat loss and temperature measurement are susceptible to variation due to the influence of the external environment;

[0012](5) Installation and disassembly are very cumbersome and labor-intensive, so that the conventional heat pipe performance testing device is only suitable for small-scale heat pipe testing on a laboratory scale, and is completely unable to cope with mass production The testing requirements required by the manufacturing process;

[0013](6) Lack of flexibility in heat transfer performance testing for different types of heat pipes, resulting in a substantial increase in equipment and labor costs for mass production testing, and even delayed delivery

[0015] In order to meet the inspection requirements of the heat pipe mass production process, it is necessary to strictly control the quality of heat pipes with a large number and various forms; It is necessary to use a large number of testing machines at the same time, and these testing machines need to be repeatedly used for a long time and frequently; 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 Control and control; the quality of the testing device will directly affect the yield and cost of production, and the industry will inevitably face multiple challenges in the accuracy, convenience, speed, consistency, reproducibility, and reliability of a large number of testing; In view of this, it is necessary to greatly improve the current heat pipe detection device, so as to incorporate the modular design of assembly, operation, and component manufacturing to meet the detection requirements of the heat pipe mass production process
