Description

Technical Field

[0001] The present application relates to the technical field of heat dissipation module detection, and specifically to a heat dissipation performance detection device for a heat dissipation module. Background Art

[0002] The heat dissipation module is a device used to conduct heat away from the heat source to ensure the normal operating temperature of the equipment. It is mainly composed of a radiator and a cooling fan. The radiator is generally made of metal (such as aluminum or copper) and has a large heat dissipation area. The heat is transferred from the heat source to the radiator through heat conduction; the cooling fan accelerates the heat dissipation through air flow, taking away the heat from the radiator, thereby reducing the temperature of the heat source; The heat dissipation module is a key component to ensure the stable operation of electronic equipment. The heat dissipation performance of the heat dissipation module directly affects the reliability and service life of the equipment. Therefore, the heat dissipation performance of the heat dissipation module needs to be tested when it is put into use to ensure the normal operation of the equipment.

[0003] The patent with publication number CN220819452U discloses a radiator heat dissipation performance test device, including a test box, a base, an electric cylinder, a rack plate, a transmission gear, an adjustment disk, a waist-shaped groove and a slide groove.

[0004] Although the above device realizes changing the heat distribution in the test box by adjusting the distance between the three heating tubes, so as to test the heat dissipation performance of the radiator under different temperature conditions, the heat dissipation module is likely to accumulate dust over time during use, if the influence of dust on the heat dissipation effect is not considered, it may lead to inaccurate evaluation of the performance of the heat dissipation module. In the actual use environment, the adhesion of dust will reduce the heat dissipation capacity of the heat dissipation module, which may affect the normal operation and life of the equipment.

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0022] Embodiment 1: Figure 1-Figure 4 As shown, the present application provides a heat dissipation performance detection device for a heat dissipation module, comprising a detection rack 1, the detection rack 1 having a detection table 101, and a detection mechanism 2 installed on the detection table 101, the detection mechanism 2 is used for heat dissipation detection of the heat dissipation module, and the detection mechanism 2 comprises a detection box 201 fixedly installed on the detection table 101; A support platform 202 is fixedly installed on the test platform 101 and inside the test box 201, and a mounting plate 203 is fixedly installed on the support platform 202. The mounting plate 203 is used to support the heat dissipation module, and there is a certain gap between the support platform 202 and the mounting plate 203, and the support platform 202 and the mounting plate 203 are both hollow structures to allow heat flow to penetrate; Two groups of pressing blocks 204 are fixedly installed near both ends of the mounting plate 203, and the pressing blocks 204 are used to press the heat dissipation module onto the mounting plate 203. Two groups of pillars 205 are fixedly installed on the top of the inner wall of the detection rack 1, and the pillars 205 extend into the detection box 201. A first mounting seat 206 is connected between the two groups of pillars 205, and a bracket plate 207 is fixedly installed on the first mounting seat 206. A heating rod 208 is installed on the bracket plate 207, and the heating rod 208 is used to simulate a heat source; A first temperature sensor 209 is plugged into the side of the detection box 201. The detection end of the first temperature sensor 209 passes through the detection box 201 and the bracket plate 207 in sequence and is located at the upper end of the heating rod 208. The first temperature sensor 209 is used to measure the heating temperature of the heating rod 208. A cover 211 is fixedly mounted on one side of the bracket plate 207 close to the detection table 101, and a fan (not shown in the figure) is fixedly mounted on the cover 211, and the fan is suitable for blowing the heat flow formed by the heating rod 208 to the heat dissipation module. At the same time, a second temperature sensor 210 is plugged into the side of the detection box 201, and the detection end of the second temperature sensor 210 passes through the detection box 201 and is located in the gap between the support table 202 and the mounting plate 203, so as to detect the temperature of the airflow that completes the heat dissipation through the heat dissipation module; like Figure 4 As shown, multiple groups of air pumps 212 are installed on the test bench 101, and the air pumps 212 are used to discharge the hot air flow on the heat dissipation module, and the air pumps 212 have an air inlet and an exhaust port, and the air inlet is close to the heat dissipation module placed on the mounting plate 203, and the exhaust port is far away from the heat dissipation module placed on the mounting plate 203, so that the hot air flow in the test box 201 can be discharged by the air pumps 212 to avoid excessive temperature in the test box 201; In summary: when the heat dissipation of the heat dissipation module is tested, the heat dissipation module is first placed on the mounting plate 203, and the heat dissipation module is pressed on the mounting plate 203 by the action of the pressing block 204, and then the heating rod 208 is started and a period of time is waited until the temperature detected by the first temperature sensor 209 is in a stable state, and then the fan is started and the heat flow formed by the heating of the heating rod 208 is blown to the heat dissipation module, and then the second temperature sensor 210 is used to detect the temperature of the air flow after the heat dissipation of the heat dissipation module, and compared with the temperature detected by the first temperature sensor 209, so as to obtain the heat dissipation of the heat dissipation module; At this time, the air pump 212 is synchronously in the start-up state, and the hot air flow in the detection box 201 is discharged through the air pump 212 to prevent the temperature in the detection box 201 from being too high.

[0023] Embodiment 2: Since the heat dissipation module is likely to accumulate dust over time during use, if the effect of dust on the heat dissipation effect is not considered, the evaluation of the heat dissipation module performance may be inaccurate; In order to solve the above problems, Figure 3 and Figure 5-Figure 7As shown, a cleaning mechanism 3 is installed inside the detection rack 1, and the cleaning mechanism 3 includes a bottom plate 301 placed on the detection table 101, and the bottom plate 301 has four groups of support columns (not shown in the figure), and the support columns make the bottom plate 301 have a certain distance from the detection table 101, and three groups of placement grooves 302 are opened on the bottom plate 301, and the placement grooves 302 are used for the airflow cooled by the heat dissipation module to pass through, and are suitable for being sucked by the air pump 212; At the same time, an installation step (not marked in the figure) is provided at the upper end of the placement groove 302, and an insert 305 is placed on the installation step. At the same time, a mounting beam 303 is opened inside the placement groove 302, and the position of the mounting beam 303 is lower than the mounting step, and multiple groups of first cylinders 304 are fixedly installed on the mounting beam 303. The telescopic end of the first cylinder 304 passes through the mounting beam 303 and is fixedly connected to the insert 305, so that the insert 305 is suitable for moving with the telescopic end of the first cylinder 304 to be suitable for approaching or moving away from the heat dissipation module. The upper end of the insert 305 is provided with a plug-in portion adapted to the airflow channel on the heat dissipation module. It can be understood that there are multiple groups of airflow channels on the heat dissipation module for hot air flow to pass through, so that the hot air flow can exchange heat with the heat dissipation module through the airflow channel, thereby achieving the effect of cooling the hot air flow; And right angle brackets 306 (such as Figure 8 As shown), a vertical rod 307 is movably inserted on the mounting plate 203, a tray 309 is fixedly installed at the lower end of the vertical rod 307, and a first spring 308 is sleeved on the vertical rod 307, one end of the first spring 308 is connected to the bottom surface of the mounting plate 203, and the other end is connected to the tray 309, and the bottom surface of the tray 309 is in contact with the right angle frame 306; Therefore, when the telescopic end of the first cylinder 304 passes through the mounting beam 303 and drives the plug 305 to approach the heat dissipation module, until the plug 305 is engaged in the air flow channel of the heat dissipation module through the plug-in portion, the heat dissipation area of ​​the heat dissipation module is partially blocked to simulate the heat dissipation of the heat dissipation module when dust is attached to the heat dissipation module. In this embodiment, the plug-in portion is made of a heat-insulating material to isolate the heat exchange between the hot air flow and the heat dissipation module; like Figure 7As shown, a connection panel 310 is fixedly installed inside the detection rack 1, and a second cylinder 311 is fixedly installed on the connection panel 310. The telescopic end of the second cylinder 311 movably penetrates the detection table 101, so that the telescopic end of the second cylinder 311 is suitable for starting to gradually approach the bottom plate 301, and then suitable for driving the bottom plate 301 to move upward, and synchronously driving the three groups of plug-ins 305 to move upward, so that the plug-ins 305 are close to or away from the heat dissipation module, so as to clean the dust attached to the pores of the heat dissipation module. In the process of the bottom plate 301 moving upward, it can be guided by the vertical rod 307 to ensure the stability of the bottom plate 301 moving upward and resetting. like Figure 5-Figure 9 As shown, a control unit is installed on the right angle frame 306, and the control unit includes a control panel 312 fixedly installed on the right angle frame 306, and the control panel 312 has a first slideway 313 arranged vertically, and a cross bar 314 is installed between the two groups of pillars 205, and a control rod 315 is hingedly installed on the bottom surface of the cross bar 314, and the control rod 315 has a control ball (not shown in the figure), and the control ball is in the first slideway 313 in the default state, and a first switch (not shown in the figure) is arranged at the first slideway 313, and the first switch is used to control the air pump 212 to be in the off state; It should be noted that when the control ball is away from the first slideway 313, the control ball no longer presses the first switch, and the air pump 212 is in a closed state; A second slideway 316 is connected to the first slideway 313, and the bottom of the second slideway 316 is lower than the bottom of the first slideway 313, so that after the control ball slides from the first slideway 313 into the second slideway 316, it cannot return from the second slideway 316 to the first slideway 313; A third slide 318 is connected to the second slide 316, the bottom of the third slide 318 is lower than the bottom of the second slide 316, and a first step is provided between the third slide 318 and the second slide 316, so that after the control ball slides from the second slide 316 into the third slide 318, it cannot return from the third slide 318 to the second slide 316, and a first vertex 317 is provided at the connection between the third slide 318 and the second slide 316, and the first vertex 317 is in the third slide 318; A fourth slideway 321 is connected to the third slideway 318. The bottom of the fourth slideway 321 is lower than the bottom of the third slideway 318. A second step (not shown) is provided between the fourth slideway 321 and the third slideway 318. Therefore, after the control ball slides from the third slideway 318 into the fourth slideway 321, it cannot return from the fourth slideway 321 to the third slideway 318. A fifth slide 323 is connected to the fourth slide 321, the groove bottom height of the fifth slide 323 is lower than the groove bottom height of the fourth slide 321, and a third step (not shown in the figure) is provided between the fourth slide 321 and the fifth slide 323, so that after the control ball slides from the fourth slide 321 into the fifth slide 323, it cannot return from the fifth slide 323 to the fourth slide 321, and a second vertex 322 is provided at the connection between the fourth slide 321 and the fifth slide 323, the second vertex 322 is in the fifth slide 323, and the second vertex 322 has the same height as the first vertex 317, and a second switch (not shown in the figure) is provided at the second vertex 322, and the second switch is used to control the air pump 212 to be in an open state; Meanwhile, a third cylinder 324 is fixedly mounted on the control panel 312, and a movable stopper 319 is fixedly mounted on the telescopic end of the third cylinder 324. The upper surface of the movable stopper 319 is in an inclined state so that the transition between the third slideway 318 and the fifth slideway 323 is smooth, and the movable stopper 319 is suitable for being raised and lowered along with the telescopic end of the third cylinder 324, so as to form a stop point 320 for the control ball to stop between the movable stopper 319 and the third slideway 318 or form a sixth channel for the control ball to pass through. It should be noted that, in the initial state, the movable stopper 319 descends along with the telescopic end of the third cylinder 324 to form the sixth channel; At the same time, the fifth slide 323 is connected with the first slide 313 and the sixth slide, and a transition slope (not shown in the figure) is provided at the connection between the fifth slide 323 and the first slide 313. The transition slope gradually increases along the position close to the first slide 313, and the highest position of the transition slope is higher than the position of the groove bottom of the first slide 313 to form a fourth step. In summary: the second cylinder 311 is activated to push the bottom plate 301, and the bottom plate 301 drives the three groups of inserts 305 to move upward. At this time, the right-angle frame 306 gradually squeezes the first spring 308, and the control ball synchronously slides from the first slide 313 into the second slide 316. As the second cylinder 311 reaches the specified stroke, the insert 305 passes through the air flow channel of the heat dissipation module and protrudes from the upper surface of the heat dissipation module, and the control ball synchronously abuts against the first vertex 317. Then, as the second cylinder 311 is reset, the bottom plate 301 gradually moves away from the heat dissipation module under the action of the first spring 308. At this time, the control ball synchronously slides from the first vertex 317 into the third slide 318, and then slides from the third slide 318 into the sixth slide, and finally slides from the sixth slide into the fifth slide 323 and returns to the first slide 313. At this time, the dust cleaning of the airflow channel of the heat dissipation module is completed to prevent impurities from remaining in the airflow channel of the heat dissipation module during the production process, thereby affecting the accuracy of the heat dissipation module detection; Any group of first cylinders 304 is started again to push a group of inserts 305, and the inserts 305 drive the control plate 312 to move upward. At this time, the control ball synchronously slides from the first slideway 313 into the second slideway 316, and as the first cylinder 304 reaches the specified stroke, the inserts 305 pass through the pores of the heat dissipation module and protrude from the upper surface of the heat dissipation module, and the control ball synchronously abuts against the first vertex 317; As the first cylinder 304 is reset, the bottom plate 301 gradually moves away from the heat dissipation module under the action of the first spring 308. At this time, the control ball synchronously slides from the first vertex 317 into the third slideway 318 and is at the stop point 320. At this time, the upper end surface of the insert 305 is flush with the upper surface of the heat dissipation module, and a certain position of the heat dissipation module can be blocked to simulate the different heat dissipation effects of the heat dissipation module when dust is blocked at different positions of the heat dissipation module. Then, by starting the heating rod 208 and waiting for a period of time, when the temperature detected by the first temperature sensor 209 is in a stable state, the fan is started and the heat flow formed by the heating of the heating rod 208 is blown to the heat dissipation module. At this time, the heat flow passes through any two unblocked positions on the heat dissipation module, and then the second temperature sensor 210 detects the temperature of the air flow after the heat dissipation through any two unblocked positions on the heat dissipation module, and compares it with the temperature detected by the first temperature sensor 209 to obtain the heat dissipation performance of the heat dissipation module, thereby detecting whether the dust attached to the copper tube of the heat dissipation module affects the heat dissipation performance of the heat dissipation module. At the same time, the heat dissipation module can be used in sections according to actual conditions to avoid repeated use of a certain area of ​​the heat dissipation module, thereby causing the heat dissipation performance of the heat dissipation module to be poor. After the detection is completed, the first cylinder 304 is started again to push the insert 305, and the control ball slides synchronously from the stop point 320 into the fourth slide 321, and as the first cylinder 304 reaches the specified stroke, the control ball abuts against the second vertex 322 and presses the second switch, and the air pump 212 is synchronously turned on at this time, and the hot air flow in the detection box 201 is discharged through the air pump 212 to avoid long-term detection and excessive temperature in the detection box 201. At the same time, the insert 305 is still gradually moved away from the heat dissipation module under the action of the first spring 308, until the insert 305 is engaged and placed on the placement slot 302 to restore the initial state; Through the above process, not only is it achieved that the second cylinder 311 drives the base plate 301 to move upward as a whole to perform preliminary cleaning of the airflow channel of the heat dissipation module, but it is also achieved that the first cylinder 304 drives any group of plugs 305 on the base plate 301 to block the airflow channel of the heat dissipation module to simulate the heat dissipation performance of the heat dissipation module when the airflow channel of the heat dissipation module is blocked.
