[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0050] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0051] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0052] The basic structure of a heat pipe radiator consists of fins, a base plate, and heat pipes. The fins are arranged in parallel and mounted on one side of the base plate. A slot is defined on the side of the base plate away from the fins. The heat pipe is secured to the slot by soldering, gluing, or direct fitting, tightly integrating it with the base plate to form the heat pipe radiator. The side of the heat pipe in contact with the slot is semicircular to increase the heat transfer area. The heat pipe surface at the slot opening is flat and flush with the adjacent base plate surface, allowing it to align with the heat-generating power module. Heat pipes typically utilize the phase change of liquids at different temperatures to achieve rapid heat transfer. One end of the heat pipe (called the evaporating end or heating end) absorbs heat, causing the liquid inside (usually water or another working fluid) to evaporate into gas. The evaporated gas, driven by a slight pressure difference within the heat pipe, flows along the heat pipe toward the other end (called the condensing end or cooling end). Upon reaching the condensing end, the gas releases heat due to the lower temperature and condenses back into a liquid state. The condensed liquid flows back to the evaporation end through the capillary structure inside the heat pipe or due to the surface tension and gravity of the liquid, ready to be heated and evaporated again. This process is repeated over and over again, allowing heat to be quickly transferred from one end of the heat pipe to the other.

[0053] Obviously, heat pipes transfer heat mainly through the movement of heat-carrying gas. According to the applicant's research, gravity has a direct impact on the heat transfer efficiency of heat pipes. When the evaporation end of the heat pipe is lower than the condensation end, the capillary reflux direction of the condensate is the same as the direction of gravity, and the efficiency of the heat pipe will be improved. This is called the "follow-gravity" working condition. On the contrary, when the evaporation end is higher than the condensation end, the capillary reflux direction of the condensate is opposite to gravity, and the efficiency of the heat pipe will decrease to a certain extent. This is called the "anti-gravity" working condition. When the evaporation end and the condensation end of the heat pipe are in the same plane, gravity has little effect on the reflux process of the condensate, and the heat pipe is in a "horizontal" working condition. And the longer the heat pipe is, the more obvious the impact of gravity is.

[0054] Since the efficiency of heat pipes varies under different working conditions, the heat dissipation efficiency of heat pipe radiators under three working conditions must be considered when testing heat pipe radiators. Temperature rise testing can provide verification data in the R&D sample stage of heat pipe radiators and provide inspection data in the mass production stage. Therefore, temperature rise testing is an indispensable test in the R&D, manufacturing and production of heat pipe radiators. At present, performing temperature rise testing requires a dedicated test device, including a bracket, pneumatic cylinder, buffer assembly and detection assembly. The heating module is pressed against the radiator by the pneumatic cylinder and buffer assembly. During the temperature rise test, the applicant found that a set of test equipment can only test the heat dissipation efficiency of the radiator under one working condition. If data under different working conditions need to be tested, different test equipment needs to be selected. When removing the radiator, it is necessary to first uninstall the pneumatic cylinder, then remove the buffer assembly and detection assembly, and finally remove the radiator from the bracket to complete the disassembly of the radiator. If the heat dissipation efficiency of the radiator under different working conditions needs to be tested, the radiator needs to be installed in another set of test equipment again, resulting in complicated process steps for temperature rise testing and a long test cycle.

[0055] In view of this, the present invention proposes a radiator testing device to solve the above technical problems.

[0056] See also Figures 1 to 4 In one embodiment of the present utility model, a radiator testing device 100 includes a side panel 1, a heat dissipation bracket 3, a heating element 6 and a detection assembly, wherein the number of side panels 1 is two, and the two side panels 1 are arranged relative to each other; the two sides of the heat dissipation bracket 3 are respectively connected to the two side panels 1, and the heat dissipation bracket 3 is provided with a mounting hole 31, and the mounting hole 31 is used to install the radiator 300; the heating element 6 is used to simulate the heating of the heating module, and the heating element 6 includes a contact surface 61, and the contact surface 61 is used to be fitted with the heat pipe 320 of the radiator 300; the detection assembly is used to detect the temperature of the contact surface 61 and the radiator 300; the radiator testing device 100 also includes a horizontal test state and a vertical test state. When the radiator testing device 100 is in the horizontal test state, the heat dissipation bracket 3 is arranged horizontally; when the radiator testing device 100 is in the vertical test state, the heat dissipation bracket 3 is arranged vertically.

[0057] Specifically, the radiator testing device 100 is supported on the ground by two side panels 1. The portions of the two side panels 1 that support the ground are on the same horizontal plane. By flipping the side panels 1, the radiator testing device 100 can be flipped as a whole, so that the other edge of the side panels 1 is supported on the ground, thereby changing the gravity state of the heat dissipation bracket 3 and, in turn, the testing conditions of the radiator 300. In this embodiment, the side panels 1 comprise rectangular panels with rounded corners. The two side panels 1 have the same shape, specifications, and opening locations. When the length direction L of the side panels 1 is parallel to the ground, the radiator testing device 100 is in a horizontal state. At this time, installing the radiator 300 in the heat dissipation bracket 3 can test the heat dissipation efficiency of the radiator 300 in the "horizontal" operating condition. By flipping the side panel 1 90° so that its width direction W is parallel to the ground, the radiator testing device 100 is now in a vertical position. Based on the layout of the heat pipes 320 in the radiator 300, if the evaporation end of the heat pipe 320 is lower than the condensation end, the heat dissipation efficiency of the radiator 300 under "gravity-oriented" conditions can be tested. If the evaporation end of the heat pipe 320 is higher than the condensation end, the heat dissipation efficiency of the radiator 300 under "reverse gravity" conditions can be tested. By flipping the side panel 1 180°, the radiator 300 can be switched between "gravity-oriented" and "reverse gravity" conditions. It should be noted that the dimensions of the side panels 1 in both the length direction L and the width direction W are larger than the corresponding dimensions of the heat sink bracket 3 and other components in the same direction. This arrangement allows all parts of the radiator testing device 100, except for the two side panels 1, to be away from the ground, thereby avoiding bumps when flipping the radiator testing device 100. At the same time, it achieves the effect of using only the side panels 1 to support the ground, and thus the test conditions of the entire radiator testing device 100 can be adjusted simply by flipping the side panels 1. It should also be noted that in this embodiment, the heat sink bracket 3 and the side panels 1 are connected by threads. This arrangement facilitates the replacement of heat sink brackets 3 of different sizes to accommodate different models of radiators 300. In addition, each side panel 1 is provided with two gripping holes 11, which are respectively provided at both ends of the side panel 1 along the length direction L. The provision of the gripping holes 11 makes it more convenient and labor-saving for the tester to flip the side panel 1. In this embodiment, the detection component includes multiple temperature sensors, a temperature collector, a processor and a display. A temperature sensor is provided at the contact surface 61 of the heating element 6 to detect the actual temperature of the heating element 6. Multiple temperature sensors are arranged on the heat pipe 320 and the substrate 310 to detect the temperature rise data at different positions. The collected data is transmitted to the temperature collector, and the detection results are displayed on the display after statistical processing by the processor.

[0058] In the technical solution provided in this embodiment, the radiator testing device 100 includes a side panel 1, a heat dissipation bracket 3, a heating element 6 and a detection assembly, wherein the number of side panels 1 is two, and the two side panels 1 are arranged relative to each other; the two sides of the heat dissipation bracket 3 are respectively connected to the two side panels 1, and the heat dissipation bracket 3 is provided with a mounting hole 31, and the mounting hole 31 is used to install the radiator 300; the heating element 6 is used to simulate the heating of the heating module, and the heating element 6 includes a contact surface 61, and the contact surface 61 is used to be fitted with the heat pipe 320 of the radiator 300; the detection assembly is used to detect the temperature of the contact surface 61 and the radiator 300; the radiator testing device 100 also includes a horizontal test state and a vertical test state. When the radiator testing device 100 is in the horizontal test state, the heat dissipation bracket 3 is arranged horizontally; when the radiator testing device 100 is in the vertical test state, the heat dissipation bracket 3 is arranged vertically. Through this arrangement, after the radiator 300 is installed on the heat dissipation bracket 3, the side panel 1 can be manually flipped to drive the heat dissipation bracket 3 to rotate, so that the heat dissipation bracket 3 can be switched between the horizontal position and the vertical position, thereby driving the radiator 300 to switch between the horizontal state and the vertical state. The heat dissipation efficiency of the radiator 300 in the horizontal and vertical states can be conveniently tested without disassembling any components. The testing process is convenient and fast, and takes less time, which can reduce the time required for a test cycle of the radiator 300.

[0059] More specifically, in one embodiment of the present invention, two side panels 1 are symmetrically arranged on either side of the heat sink bracket 3. The side panels 1 include two first support surfaces 12 arranged opposite to each other, and two second support surfaces 13 arranged opposite to each other. The first support surfaces 12 and the second support surfaces 13 are arranged alternately, and adjacent first support surfaces 12 and second support surfaces 13 are arranged perpendicularly. The side panels 1 can rotate synchronously relative to the ground to drive the heat sink bracket 3 to rotate. When the radiator test device 100 is in a horizontal test state, one of the first support surfaces 12 is supported on the ground. When the radiator test device 100 is in a vertical test state, one of the second support surfaces 13 is supported on the ground. The first support surface 12 and the second support surface 13 are both rectangular. The length direction of the first support surface 12 is the same as the length direction of the side panel 1, and the length direction of the second support surface 13 is the same as the width direction of the side panel 1. Because the side panels 1 are rectangular, two first support surfaces 12 and two second support surfaces 13 are disposed on each side panel 1 in opposing relation. When the radiator testing apparatus 100 is in the horizontal test state, one of the first support surfaces 12 of each side panel 1 rests on the ground, and the heat sink bracket 3 is horizontal. Depending on the installation orientation of the radiator 300 being tested, the tester can independently select one of the two first support surfaces 12 on each side panel 1 and place it against the ground, thereby placing the radiator 300 in the "horizontal" test state. By flipping the side panels 1 90°, the radiator testing apparatus 100 enters the vertical test state, with the second support surface 13 of the side panels 1 resting on the ground and the heat sink bracket 3 positioned vertically. By flipping the side panels 1 90° again, the radiator testing apparatus 100 can be returned to the horizontal test state. In this way, simply flipping the side panels 1 can change the test state of the radiator testing apparatus 100, thereby changing the test conditions of the radiator 300.

[0060] Furthermore, in one embodiment of the present invention, the radiator testing device 100 further includes a bottom plate 2, the two sides of which are connected to the two side plates 1 respectively. The bottom plate 2, the heat dissipation bracket 3 and the two side plates 1 enclose a heat dissipation duct 7. The fins 330 of the radiator 300 are arranged toward the bottom plate 2 and disposed in the heat dissipation duct 7. The heating element 6 is installed on the side of the radiator 300 away from the heat dissipation duct 7. Figure 2, when the length direction L of the side panel 1 is parallel to the ground, the bottom plate 2 is horizontally installed between the two side panels 1, and the bottom plate 2 is threadedly connected to the side panels 1, so that the bottom plates 2 of different sizes can be replaced according to different radiator 300 models or test requirements. By setting the bottom plate 2, the layout of the heat dissipation duct 7 is closer to the actual use environment of the radiator 300. The heat dissipation duct 7 is set through along the length direction L of the side panel 1, and its two ends are open so that the heat dissipation duct 7 can be connected to the outside world. The fins 330 in the radiator 300 are set in the heat dissipation duct 7, and the heating element 6 is set on the side of the substrate 310 away from the fins 330. This setting, combined with the setting of the heat dissipation duct 7, can simulate the actual use conditions of the radiator 300 in the equipment, so as to reduce the error between the test results and the heat dissipation efficiency during actual use.

[0061] However, the traditional temperature rise test device does not have the design of the heat dissipation duct 7, and since the bracket of the traditional temperature rise test device is relatively compact and adopts an up-down layout design, the radiator 300 is placed directly on the ground, so it is difficult to install the heat dissipation duct 7 on the basis of the traditional temperature rise test device.

[0062] Furthermore, the radiator testing device 100 further includes an exhaust component 4, which is disposed at one end of the heat dissipation duct 7 to promote air flow in the heat dissipation duct 7. Figure 1 and Figure 2 By adding an exhaust assembly 4 to one end of the heat dissipation duct 7, the operating conditions of the heat dissipation duct 7 equipped with the exhaust assembly 4 can be simulated during actual use of the radiator 300. In one embodiment, the exhaust assembly 4 is connected to the heat dissipation bracket 3 and the bottom plate 2 on either side of the width direction W of the side panel 1. In another embodiment, the exhaust assembly 4 is connected to both side panels 1 on either side. The provision of the exhaust assembly 4 accelerates the air flow in the heat dissipation duct 7, thereby more effectively removing heat and improving overall heat dissipation efficiency.

[0063] The exhaust assembly 4 can be implemented in various ways. In one embodiment, the exhaust assembly 4 includes a mounting plate 41 and a fan 42. The mounting plate 41 is mounted at one end of the heat dissipation duct 7. The mounting plate 41 is connected to the two side panels 1 on either side. The mounting plate 41 is provided with ventilation holes. The fan 42 is mounted on the mounting plate 41, and the rotational center of the fan blades of the fan 42 is arranged to correspond to the central axis of the ventilation holes. The fan 42 is removably mounted to the mounting plate 41, and the connection method includes a bolt connection, a screw connection, and a snap connection. This arrangement makes the removal and assembly process of the fan 42 more convenient and faster when replacement or maintenance is required. In addition, in this embodiment, the mounting plate 41 and the fan 42 are arranged in a corresponding manner. The fan 42 has a variety of models depending on the power, and each model of the fan 42 is equipped with a mounting plate 41. The opening area of ​​the ventilation holes in each mounting plate 41 is different, and the opening area of ​​the mounting plate 41 is set in a one-to-one correspondence with the model of the fan 42. By replacing different mounting plates 41 and fans 42, heat dissipation conditions under various working conditions can be simulated.

[0064] In another embodiment, the exhaust component 4 includes an air supply pump, and the air supply port of the air supply pump is arranged toward one end of the heat dissipation duct 7. In some high-heat-generating equipment, air is usually forced into the heat dissipation duct 7 to more quickly take away the heat generated by the radiator 300, thereby avoiding local overheating of the radiator 300 and affecting the heat dissipation efficiency of the radiator 300. The setting in this embodiment can simulate the working condition of the radiator 300 under forced air exchange conditions.

[0065] In one embodiment of the present invention, the heat sink testing device 100 further includes a top shell 5, which is mounted on the heat dissipation bracket 3 and covers the heating element 6. Figures 1 to 3 After the top shell 5 is installed on the heat sink, a protective cavity is formed between the top shell 5 and the heat sink. The heating element 6 is set in the protective cavity. The heating element 6 is used to simulate the heating module of the device. The heating module in the actual device is usually provided with a protective shell. Therefore, the top shell 5 is provided in this embodiment to simulate the actual environment in which the heating module is located. In addition, by providing the top shell 5, it is possible to prevent the tester from accidentally triggering the heating element 6 during the test, thereby improving the safety of the radiator testing device 100. In addition, the top shell 5 is also provided with a wire hole 51. The wire hole 51 is used for the cable in the detection component to pass through, and it is convenient for the tester to hold the top shell 5 to speed up the disassembly and assembly process of the top shell 5.

[0066] In one embodiment of the present invention, the heating element 6 includes a heat conductor 62, a protrusion 63 and a heating rod (not shown in the figure). The heating rod is plugged into the heat conductor 62. A protrusion 63 is provided on one side of the heat conductor 62. The protrusion 63 is provided with a contact surface 61. Figure 5To ensure that the contact surface 61 can reach the temperature reached by the heating module in the device, in this embodiment, a heating rod is inserted into a heating hole 64 provided in the heat conductor 62. The gap between the heating rod and the heating hole 64 is filled with thermal grease to improve the heat transfer efficiency between the heat conductor 62 and the heating rod. There are multiple heating holes 64, and the number of heating rods can be selected based on actual conditions. Generally, the number of heating rods is less than or equal to the number of heating holes 64. This arrangement allows the temperature of the contact surface 61 to be controlled by adding or subtracting the number of heating rods, thereby increasing the flexibility of temperature control of the contact surface 61.

[0067] Furthermore, in one embodiment of the present invention, the heat conductor 62 is provided with at least two fixing holes 621, and the heating element 6 is screwed to the heat sink 300 through the fixing holes 621. Figure 5 In this embodiment, the heating element 6 is an independent structure, that is, only one contact surface 61 is provided in each heating element 6, and each heat conductor 62 is only used to transfer heat to one contact surface 61. By providing a fixing hole 621 on the heat conductor 62 and threading the heating element 6 to the radiator 300 through the fixing hole 621, the position of the heating element 6 can be adjusted according to the test requirements of different working conditions, and the heating element 6 is set as an independent structure, and the combined shapes of multiple heating elements 6 can be flexibly combined when using multiple heating elements 6 to simulate heating modules of different shapes. Or multiple heating elements 6 can be arranged at intervals to simulate the working condition of multiple heating modules in the same device. Through the technical solution in this embodiment, the installation and combination forms of the heating element 6 are varied, so that the heating element 6 can perform heating simulation under various working conditions. In addition, the heating module in the device is usually connected to the radiator 300 by a threaded connection. In this solution, a pneumatic cylinder is not used to press the heating element 6 to the radiator 300, but a threaded connection is used to fix the heating element 6 to the radiator 300. This can more realistically simulate the connection method between the heating module in the device and the radiator 300, so that the detection results are more credible.

[0068] See also Figure 5 In one embodiment of the present invention, the protrusion 63 defines a groove 631. The detection assembly includes a heat source temperature sensor, and groove 631 is used to mount the heat source temperature sensor. This arrangement allows the temperature near the contact surface 61 to be detected as accurately as possible. Furthermore, mounting the heat source temperature sensor in groove 631 avoids affecting the flatness of groove 631, thereby preventing any impact on the heat transfer efficiency between the contact surface 61 and the substrate 310 of the heat sink 300.

[0069] In one embodiment of the present invention, please refer to Figure 3The heat sink bracket 3 is provided with a slot 32, which is connected to the mounting hole 31. The slot 32 is used to expose part of the side of the radiator 300 to facilitate the installation or removal of the radiator 300. In this embodiment, there are two slots 32, which are respectively provided on both sides of the heat sink bracket 3 near the two side panels 1. The length and width of the slot 32 are based on the size of the slot 32. The slot 32 is connected to the mounting hole 31 of the heat sink bracket 3, and the radiator 300 is installed in the mounting hole 31. This arrangement makes it more convenient for the tester to place and remove the radiator 300, and the placement and removal of the radiator 300 can be completed without the use of other tools.

[0070] The present invention also proposes a test structure, which includes a radiator test device 100. The specific structure of the radiator test device 100 refers to the above embodiment. Since this test structure adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0071] Among them, the test structure also includes an auxiliary bracket 200, which includes a horizontal positioning rod 210, a vertical positioning rod 220 and a positioning pin. The height of the horizontal positioning rod 210 from the ground is greater than the length of the radiator test device 100, and the side panel 1 is rotatably installed at the connection between the horizontal positioning rod 210 and the vertical positioning rod 220. The side panel 1 is provided with a socket, the horizontal positioning rod 210 is provided with a horizontal positioning hole, and the vertical positioning rod 220 is provided with a vertical positioning hole; when the radiator test device 100 is in a horizontal test state, the positioning pin is simultaneously plugged into the horizontal positioning hole and the socket; when the radiator test device 100 is in a vertical test state, the positioning pin is simultaneously plugged into the vertical positioning hole and the socket.

[0072] Please refer to the following for details: Figures 6 to 8In this embodiment, the evaporation end of the heat pipe 320 is arranged near the exhaust assembly 4, and the auxiliary bracket 200 is used to assist the rotation of the radiator test device 100, rotating the length direction L of the side panel 1 to be parallel to the ground, and the top shell 5 is away from the ground relative to the bottom plate 2. At this time, the radiator 300 is in a "horizontal" working condition. In order to fix the radiator test device 100, two sockets are opened on the side panel 1, a horizontal positioning hole is opened on the horizontal positioning rod 210, and a vertical positioning hole is opened on the vertical positioning rod 220. When the radiator 300 is in the "horizontal" working condition, it is necessary to use a positioning pin to pass through the horizontal positioning hole and the socket to set the radiator 300 horizontally. When it is necessary to test other working conditions, pull out the positioning pin and rotate the side panel 1 clockwise or counterclockwise. When the width direction W of the side panel 1 is parallel to the ground and the exhaust assembly 4 is set toward the ground, the radiator test device 100 is in a vertical state as a whole, and the evaporation end of the heat pipe 320 is lower than the condensation end. At this time, the radiator 300 is in a "follow-gravity" working condition. At this time, the positioning pin needs to be passed through the vertical positioning hole and the socket to prevent the radiator test device 100 from rotating unexpectedly as a whole. After the "follow-gravity" working condition test is completed, pull out the positioning pin and flip the side panel 1 180°. At this time, the exhaust assembly 4 is set away from the ground, the evaporation end of the heat pipe 320 is higher than the condensation end, and the radiator 300 is in a "counter-gravity" working condition. At this time, the positioning pin needs to be passed through the vertical positioning hole and another socket to fix the radiator test device 100. By setting up the auxiliary bracket 200, the placement state (horizontal state or vertical state) of the radiator testing device 100 can be more conveniently converted to change the test working conditions of the radiator 300 ("horizontal" working condition, "with gravity" working condition and "against gravity" working condition), further saving the time occupied by a test cycle of the radiator 300.

[0073] When adjusting the placement of the radiator testing device 100, for the safety of the tester, it is necessary to first turn off the power to the heating element 6. After the heating element 6 and the radiator 300 have completely cooled, turn off the power to the exhaust assembly 4. Finally, flip the side panel 1 to adjust the placement of the radiator testing device 100. After adjusting the radiator 300 to the desired test condition, turn on the power to the exhaust assembly 4, then turn on the power to the heating element, and then begin testing under that condition.
