Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detecting device, and more particularly to a detecting device for detecting the performance of a heat pipe. [Prior Art] The basic structure of the heat pipe is such that the inner wall of the closed pipe is lined with a porous capillary structure layer which easily absorbs the working fluid, and the central space thereof is in an open state, and the capillary structure is injected into the vacuum-tight closed pipe. The actuating fluid of the total volume of the pores can be divided into an evaporation section, a condensation section and an adiabatic section therebetween according to the relevant positions of absorption and heat dissipation. The working principle of the Lu heat pipe is that when the evaporation section absorbs heat, the liquid phase actuating fluid contained in the capillary structure layer evaporates and raises the vapor pressure, and the generated high heat steam flow is quickly moved along the central passage to the low pressure. The condensation section dissipates heat, and the condensate returns to the evaporation section to absorb heat by the capillary force of the capillary structure layer, so that the continuous heat transfer is carried out by the cycle of absorbing and dissipating a large amount of latent heat during the process of the fluid phase change. And since the liquid phase and the vapor phase of the actuating fluid coexist in the above process, the heat pipe can be widely used in various fields as a superconductor function of rapidly transferring a large amount of heat energy while the temperature is almost constant. Since the performance test of the heat pipe mainly focuses on the maximum heat transfer amount (Qmax) and the temperature difference (ΔΤ) from the evaporation section to the cooling section, the temperature can be obtained by a certain temperature in a given heat transfer condition. The thermal resistance value is known and the performance of the heat pipe is evaluated. When the given heat exceeds the maximum heat transfer capacity of the heat pipe, the thermal resistance value increases due to the destruction of the original normal heat transfer mechanism, so that the temperature of the evaporation section is increased. It has also risen sharply. A heat pipe performance detecting method in the prior art is to insert a heat pipe evaporation section into a heated temperature-temperature liquid, and after the temperature of the heat pipe is stabilized, by a temperature sensor such as a thermocouple, a resistance temperature sensor (RTD), or the like Measure the temperature difference between the temperature-receiving liquid and the condensation end of the heat pipe to evaluate the performance of the heat pipe; Only the above-mentioned conventional technology cannot effectively measure the maximum heat transfer capacity and thermal resistance of the heat pipe, so the heat transfer performance of the heat pipe cannot be accurately reflected. . Another heat pipe performance detecting device as shown in the first figure is wound on the surface of the evaporation section 2a of the heat pipe 2 by using a heating wire as a heat source, and the cooling water jacket 3 is set as a heat sink in the condensation section. 6 : 1289650 The surface 'by measuring the electric current of the heating wire 1 can give the heat pipe 2 a certain heating power, and at the same time, the heating power is removed by modulating the flow rate of the cooling water jacket 3 and the inlet water temperature, and thereby Controlling the temperature of the heat pipe 2 in the adiabatic section 2e, the temperature of the maximum scale of the wire 2 to the temperature of the condensation section 2b can be known by the temperature sensing system provided on the surface of the heat pipe 2. However, the above-mentioned provincial heat pipe test device still has the following disadvantages: · It is difficult to accurately control the length of the evaporation section and the length of the condensation section 2b, which is an important factor for evaluating the variation of heat pipe performance; and due to heat loss and 2 degrees of coffee consumption戦 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The performance testing device is only suitable for the small amount of heat pipe test in the laboratory, and it is completely unable to meet the testing requirements required for the mass production process.
