[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. Of course, the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit its scope.
[0029] Example 1:
[0030] See Figures 1-6 A heat dissipation device suitable for bench testing of wheeled armored chassis integrated hoisting assembly, including a bracket and a fan 6 installed on the upper part of the bracket, with the air outlet of the fan 6 facing downward;
[0031] The fan 6 is connected to the support beam 2 via a lifting structure 7. The lifting structure 7 allows the fan 6 to reciprocate vertically.
[0032] A shroud 601, which covers the heat sink of the test piece, is provided on the outer casing of the fan 6 and around the air outlet. It is generally flared in shape, narrow at the top and wide at the bottom, to increase the airflow speed.
[0033] The upper end of the air guide shroud 601 is circular, and the lower end is shaped to match the heat sink of the test piece. The upper end of the air guide shroud 601 is rotatably mounted on the outer casing of the fan 6. An upper ring plate 13 and a lower ring plate 14 are fixedly mounted on the outer casing of the fan 6 and located around the air outlet. An annular turntable is provided at the upper end of the air guide shroud 601, and the annular turntable is slidably mounted between the upper ring plate 13 and the lower ring plate 14.
[0034] The lower ring plate 14 has several bullseye bearings 15 evenly distributed around it, and the upper end face of the bullseye bearings 15 contacts the lower end of the annular turntable. The bullseye bearings 15 make it easier to manually rotate the air guide cover 601.
[0035] The upper ring plate 13 and the lower ring plate 14 are generally fixed to the fan housing by bolts.
[0036] The lower end of the air guide 601 is generally rectangular. The lower end face of the air guide 601 is in contact with the upper end face of the heat sink of the test piece, and preferably fits completely with the heat sink of the test piece. Since the shape of the heat sink of the test piece is generally rectangular, when the air guide 601 is connected to the heat sink of the test piece, the air guide 601 cannot fit completely with the heat sink of the test piece. At this time, by rotating the air guide 601, its position is made to correspond completely with the heat sink, thereby increasing the fit effect.
[0037] The lifting structure 7 is connected to the support beam via the horizontal guide rail 5, and the lifting structure 7 is slidably mounted on the horizontal guide rail 5.
[0038] The bracket is a door frame structure, including support column 1, support column 2, and crossbeam 2. The upper end of support column 1 and support column 2 is provided with crossbeam 2, and the lifting structure 7 is provided on crossbeam 2.
[0039] One end of the crossbeam 2 is rotatably mounted on the upper end of the support column 1, allowing the crossbeam to rotate 360 degrees. The other end of the crossbeam 2 is fixedly mounted on the upper end of the support column 3. The lower end of the support column 3 is equipped with casters 4. The crossbeam 2 is generally rotatably connected by self-aligning bearings.
[0040] The lifting structure 7 includes a mounting plate 701 and guide shafts 702. Several guide shafts 702 are fixedly installed below the mounting plate 701. A support frame 11 is fixedly connected to the fan housing. The support frame 11 is sleeved on the guide shafts 702, and a locking device for limiting the movement of the fan is provided on the support frame 11. There are no fewer than two guide shafts 702, and generally three or more are used.
[0041] The locking element is a screw 9 that is threadedly connected to the support frame 11, and the screw 9 rests on the guide shaft 702. The contact surface between the guide shaft 702 and the screw 9 is preferably flat to improve the fastening effect.
[0042] Mounting plate 701 is slidably mounted on horizontal guide rail 5, which is fixed below the support beam. Several sliders 501 are fixedly mounted on the horizontal guide rail 5 above mounting plate 701.
[0043] A fall arrestor ring 12 is fixedly installed on the guide shaft 702 and below the support frame 11.
[0044] The mounting plate 701 is equipped with a crane that drives the fan 6 to move along the guide shaft 702. For example, the crane can be a balance crane 8, the upper end of which is hung or fixed on the mounting plate 701, and the hook at the lower end of the balance crane 8 is hung on the support frame 11. The support frame 11 is equipped with a hanging ring 10 that cooperates with the hook, thereby reducing the gravity when pulling the fan 6 up and down.
[0045] The fan 6 is an axial flow fan 6, and the support frame 11 is fixedly installed on the side wall of the fan housing. The support frame 11 includes a fan mounting plate and a side plate set on the outer edge of the fan mounting plate. Screws 9 are threadedly connected to the side plate. The support frame 11 is located on the side wall of the fan housing, which does not affect the airflow path of the axial flow fan and reduces the impact on the wind speed.
[0046] Several internal support plates are installed between the fan mounting plate and the side plate.
[0047] How to use:
[0048] Place the heat sink of the test specimen directly below the fan 6. The fan 6 can be moved up and down along the guide shaft 702 by rotating the crossbeam 2, sliding it along the horizontal guide rail 5, and finally aligning the air guide shroud 601 with the heat sink of the test specimen, ideally achieving a tight seal between them. Tighten the screw 9 to press it against the guide shaft 702. Start the fan 6 to dissipate heat from the heat sink of the test specimen.
[0049] Example 2:
[0050] The difference between this embodiment and Embodiment 1 is that a different lifting structure 7 is used. The lifting structure 7 can also be a crane, hydraulic rod, electric actuator, etc. in the prior art.
[0051] Example 3:
[0052] See Figures 1-6 A heat dissipation device includes a bracket and a fan 6 disposed on the upper part of the bracket, wherein the air outlet of the fan 6 faces downward.
[0053] The fan 6 is connected to the support beam via a lifting structure 7. The lifting structure 7 allows the fan 6 to reciprocate vertically.
[0054] An air guide shroud is installed on the fan casing, around the air outlet, to cover the heat sink of the test specimen. It is generally flared, narrow at the top and wide at the bottom, to increase the airflow speed.
[0055] The upper end of the air guide shroud 601 is circular, and the lower end is shaped to match the heat sink of the test piece. The upper end of the air guide shroud 601 is rotatably mounted on the housing of the fan 6. An upper ring plate 13 and a lower ring plate 14 are fixedly mounted on the housing of the fan 6 and located around the air outlet. An annular turntable that slides between the upper ring plate 13 and the lower ring plate 14 is provided at the upper end of the air guide shroud.
[0056] The lower ring plate 14 has several bullseye bearings 15 evenly distributed around it, and the upper end face of the bullseye bearings 15 contacts the lower end of the annular turntable. The bullseye bearings 15 make it easier to manually rotate the air guide cover 601.
[0057] The upper ring plate 13 and the lower ring plate 14 are generally fixed to the fan housing by bolts.
[0058] The lower end of the air guide 601 is generally rectangular. Since the heat sink of the test piece is generally rectangular, when the air guide 601 corresponds to the heat sink of the test piece, the air guide 601 cannot completely fit the heat sink of the test piece. At this time, by rotating the air guide 601, its position is made to completely correspond with the heat sink, thereby increasing the fit.
[0059] The bracket is a door frame structure, including support column 1, support column 2, and crossbeam 2. The upper end of support column 1 and support column 2 is provided with crossbeam 2, and the lifting structure 7 is provided on crossbeam 2.
[0060] One end of the crossbeam 2 is rotatably mounted on the upper end of the support column 1, allowing the crossbeam to rotate 360 degrees. The other end of the crossbeam 2 is fixedly mounted on the upper end of the support column 3, and a caster 4 is installed at the lower end of the support column 3. The crossbeam 2 is generally rotatably connected via a self-aligning bearing.
[0061] The lifting structure 7 includes a mounting plate 701 and guide shafts 702. Several guide shafts 702 are fixedly installed below the mounting plate 701. A support frame 11 is fixedly connected to the fan housing. The support frame 11 is sleeved on the guide shafts 702, and a locking device for limiting the movement of the fan is provided on the support frame 11. There are no fewer than two guide shafts 702, and generally three or more are used.
[0062] The locking element is a screw 9 that is threadedly connected to the support frame 11, and the screw 9 rests on the guide shaft 702. The contact surface between the guide shaft 702 and the screw 9 is preferably flat to improve the fastening effect.
[0063] Mounting plate 701 is fixed to the bracket, typically directly to the crossbeam 2. A fall arrestor ring 12 is fixedly installed on the guide shaft 702, located below the support frame 11.
[0064] The mounting plate 701 is equipped with a crane that drives the fan 6 to move along the guide shaft 702. For example, the crane can be a balance crane 8, the upper end of which is hooked or fixed to the support beam, and the hook at the lower end of the balance crane 8 is hooked on the support frame 11. The support frame 11 is equipped with a hanging ring 10 that cooperates with the hook, thereby reducing the gravity when pulling the fan 6 up and down.
[0065] The fan 6 is an axial flow fan 6, and the support frame 11 is fixedly installed on the side wall of the fan housing. The support frame 11 includes a fan mounting plate and a side plate set on the outer edge of the fan mounting plate. Screws 9 are threadedly connected to the side plate. The support frame 11 is located on the side wall of the fan housing, which does not affect the airflow path of the axial flow fan and reduces the impact on the wind speed.
[0066] Several internal support plates are installed between the fan mounting plate and the side plate.
[0067] How to use:
[0068] Place the heat sink of the test specimen directly below the fan 6. The fan 6 can be moved up and down along the guide shaft 702 by rotating the crossbeam 2 until the air guide shroud 601 is aligned with the heat sink, ideally achieving a tight seal between them. Tighten the screw 9 to press it against the guide shaft 702. Start the fan 6 to dissipate heat from the heat sink.
[0069] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
