Description

Technical Field

[0001] The present invention relates to the technical field of testing tooling, and in particular to a 5G inflatable phase change temperature equalizing plate testing tooling and method. Background Art

[0002] 5G communication technology is the core cornerstone of key areas such as the future digital economy and the Internet of Things. Compared with 4G products, the heat flux density of 5G outdoor communication base stations has increased significantly, and the heat dissipation problem has become increasingly severe. It is urgent to reduce the chip temperature to improve the reliability of the product. Traditional heat dissipation optimization design often starts from improving the thermal conductivity of the interface material and optimizing the heat dissipation efficiency of the fins. However, the improvement of the thermal conductivity of the interface material is limited. If the traditional die-cast fins are made very thin, the thermal resistance of the fins will increase, which is not conducive to heat dissipation. Two-phase heat dissipation technology (such as heat pipes, flat heat pipes, etc.) has always played an important role in improving heat dissipation efficiency. If two-phase temperature-averaging heat dissipation teeth are used to replace the metal heat dissipation teeth in the outdoor communication base station radiator, the heat dissipation efficiency will be greatly improved.

[0003] The inflatable heat spreader is a new type of two-phase heat dissipation product. It has no capillary structure inside and is processed by printing, hot rolling, cold rolling, inflating and other processes. The refrigerant evaporates and condenses continuously in the plate with a specific circuit channel, relying on the phase change of the working fluid to efficiently transfer heat. The existing inflatable heat spreader needs to undergo multiple tests before research and development and production before it can be put into production and use in large quantities. The tests generally include appearance inspection, pressure test, thermal performance test, corrosion resistance test and other tests. The existing various tests require different test tools to be carried out, which leads to increased testing costs and the need to constantly disassemble and assemble test samples, resulting in low testing efficiency. Summary of the invention

[0004] In order to solve the problems of single function and low testing efficiency of test tooling, the present invention provides a 5G inflatable phase change temperature equalizing plate test tooling and method.

[0005] The present invention provides a 5G inflation-type phase change temperature equalizing plate test fixture and method using the following technical solutions:

[0007] A substrate, a test frame is fixedly connected to the top of the substrate, and a temperature equalizing plate sample is placed in the test frame;

[0008] A thermal performance testing mechanism, the thermal performance testing mechanism is arranged on the top of the substrate and connected to the surface of the temperature-averaging plate sample to form a circulation loop, the thermal performance testing mechanism includes a condenser and a compressor, the condenser and the compressor are fixedly connected to the substrate, connecting pipes are connected between the condenser, the compressor and the temperature-averaging plate sample, and throttle valves are fixedly connected to the connecting pipes at both ends of the condenser;

[0009] A pressure testing mechanism, the pressure testing mechanism is arranged on the test frame, the pressure testing mechanism comprises a cylinder, a clamping plate and a pressure gauge, two cylinders are arranged, and are respectively fixedly connected to the outer walls on both sides of the test frame, the output shaft of the cylinder extends to the inner side of the test frame and is fixedly connected to the clamping plate, the temperature equalizing plate sample is placed upright between the two clamping plates, a sliding groove is provided on the side wall of the clamping plate, the outer wall of the pressure gauge is fixedly connected to an outer sleeve rod, a movable pressure-sensing rod is slidably connected inside the outer sleeve rod, one end of the movable pressure-sensing rod is fixedly connected to the clamping plate, and an auxiliary locking piece is detachably connected to the clamping plate;

[0010] The heat source module is fitted with a side of the temperature homogenizing plate sample away from the condenser, and the auxiliary locking piece is detachably connected to the heat source module.

[0011] By adopting the above technical scheme, the thermal performance test and the pressure test are combined, so that the two tests can be carried out on one tooling, avoiding repeated disassembly and assembly of the temperature-averaging board sample, effectively improving the test efficiency, and enriching the function of the tooling. Specifically, a cooling system is formed by a condenser, a compressor, a throttle valve and an evaporator. When one side of the temperature-averaging board sample is heated, the liquid working medium distributed on the heated surface evaporates into steam and absorbs heat. The steam is cooled and condensed into liquid on the other side, and returns to the evaporation surface under gravity or capillary action to form a cycle. By changing the temperature of the heat source module, the data change of the surface temperature of the temperature-averaging board sample is observed, and the thermal performance of the temperature-averaging board sample is measured. By squeezing the temperature-averaging board sample by the clamp, the value change of the pressure gauge is observed, and the pressure resistance of the temperature-averaging board sample is measured.

[0012] Optionally, a side of the temperature homogenizing plate sample away from the heat source module is fixedly connected to an evaporator, and a thermal conductive pad is fixedly connected between the evaporator and the temperature homogenizing plate sample.

[0015] By adopting the above technical solution, the heat source module is reinforced through the rotation connection of the locking rod, and the provision of multiple threaded holes can not only perform multi-point reinforcement, but also can be reinforced according to the size of the heat source module, and has strong applicability.

[0016] Optionally, a hydraulic gauge and a thermometer are provided on the connecting pipes between the condenser and the compressor and the temperature equalizing plate sample, and the connecting pipes are connected to the evaporator.

[0017] By adopting the above technical solution, the pressure and temperature changes of the liquid in the connecting pipe can be monitored in real time through the hydraulic gauge and the thermometer, thereby reducing the probability of accidents.

[0018] Optionally, both upper and lower ends of the clamping plate are slidably connected to the inner wall of the test frame, and the height of the clamping plate is higher than the height of the temperature equalizing plate sample.

[0019] By adopting the above technical solution and setting the clamping plates, it is ensured that the temperature equalizing plate sample can be stably clamped between the two clamping plates, eliminating the clamping mechanism and making full use of the components.

[0020] Optionally, the side of the clamping plate provided with the sliding groove is located outside the test frame.

[0022] Optionally, the method for using the G-type inflation phase change temperature equalizing plate test tool comprises the following steps:

[0023] Step 1: Install the temperature plate sample, connect the two ends of the temperature plate sample to the connecting pipes, and then use the cylinder to control the movement of the clamping plate to clamp the two ends of the temperature plate sample;

[0024] Step 2: Install the heat source module, attach the heat source module to the surface of the temperature homogenizing plate sample, and then turn the locking rod to reinforce the heat source module;

[0025] Step 3: Thermal performance test: give the heat source module different temperatures, test the surface temperature and temperature difference of the temperature averaging plate sample, so as to test the heat resistance of the temperature averaging plate sample. During the test, the refrigerant is compressed by the compressor and enters the condenser to release heat. After the throttling effect of the throttle valve, it enters the evaporator and absorbs heat. The evaporator is used as a cold source. Several thermocouples are attached to the surface of the temperature averaging plate sample and the evaporator. Relevant data is obtained through the data acquisition system, and displayed and stored on the computer, so as to obtain the temperature distribution of the temperature averaging plate sample and the evaporator surface.

[0026] Step 4: Pressure test. After the thermal performance test is completed, wait for the temperature-averaging board sample to cool down, unlock the lock between the connecting plate and the clamping plate, start the cylinder to control the sliding of the clamping plate, thereby squeezing the temperature-averaging board sample, observe the shape changes of the pressure gauge and the temperature-averaging board sample, and measure the pressure resistance range of the temperature-averaging board sample.

[0027] By adopting the above technical solution, thermal performance testing and pressure testing can be completed conveniently, efficiently and at low cost.

[0028] In summary, the present invention includes at least one of the following beneficial technical effects:

[0029] 1. Combine thermal performance test and pressure test so that the two tests can be performed on one tool, avoiding repeated disassembly and assembly of the temperature plate sample, effectively improving the test efficiency, and enriching the function of the tool, with high efficiency and low cost;

[0030] 2. A cooling system is formed by a condenser, a compressor, a throttle valve and an evaporator.

The steam is cooled and condensed into liquid on the other side, and returns to the evaporation surface under gravity or capillary action to form a cycle.

[0044] The pressure testing mechanism 4 is arranged on the test frame 2. The pressure testing mechanism 4 includes a cylinder 41, a clamping plate 42 and a pressure gauge 45. Two cylinders 41 are provided and are fixedly connected to the outer walls of both sides of the test frame 2 respectively. The output shaft of the cylinder 41 extends to the inner side of the test frame 2 and is fixedly connected to the clamping plate 42. The temperature plate sample 5 is placed vertically between the two clamping plates 42. The side wall of the clamping plate 42 is provided with a sliding groove. The outer wall of the pressure gauge 45 is fixedly connected to the outer sleeve rod 44. The inner part of the outer sleeve rod 44 is slidably connected with a movable pressure-sensing rod 43. One end of the movable pressure-sensing rod 43 is fixedly connected to the clamping plate 42. The clamping plate 42 is detachably connected with an auxiliary locking member.

[0045] The heat source module 8 is fitted with a side of the temperature homogenizing plate sample 5 away from the condenser 31 , and the auxiliary locking piece is detachably connected to the heat source module 8 .

[0046] Specifically, the air cylinder 41 is started to control the movement of the clamping plate 42 to clamp the temperature-averaging plate sample 5, and a number of thermocouples are attached to the surface of the temperature-averaging plate sample 5 and the evaporator 6, and the data is connected to the computer. When the thermal performance test is performed, the temperature of the heat source module 8 is changed to observe the change in the surface temperature of the temperature-averaging plate sample 5. The condenser 31, the compressor 32, the throttle valve 34 and the evaporator 6 constitute a cooling system to complete the reciprocating operations of heat absorption, heat conduction and heat dissipation. It should be noted that when conducting the test, it is necessary to test and adjust the thermal performance of the temperature-averaging plate sample 5 under equivalent different thermal conductivities to improve the accuracy of the data. When conducting a pressure test, the air cylinder 41 is started to control the sliding of the clamping plate 42, thereby squeezing the temperature-averaging plate sample 5, observing the shape changes of the pressure gauge 45 and the temperature-averaging plate sample 5, and measuring the pressure resistance range of the temperature-averaging plate sample 5.

After the fixation is completed, the connecting plate 421 and the clamping plate 42 are fixed with screws to prevent the connecting plate 421 from sliding randomly in the horizontal direction, thereby ensuring the stability of the connection of the heat source module 8.

[0052] In the embodiment of the present invention, the state of the liquid in the connecting pipe 33 is observed in real time by the hydraulic gauge 331 and the thermometer 332. Once the safety warning value is exceeded, the test can be quickly interrupted to avoid unnecessary accidents and improve the safety of the test.

[0054] In the embodiment of the present invention, the height of the clamping plate 42 is set to provide space for the pressure gauge 45 to prevent the temperature equalizing plate sample 5 from contacting the pressure gauge 45 and affecting the accuracy of the value of the pressure gauge 45.
