Description

TECHNICAL FIELD

[0001] The utility model relates to a case heat dissipation technical field, concretely relates to a forced air cooling case. BACKGROUND

[0002] At present, various functional electronic devices are integrated in a case in a modular way, and the heat flux density inside the case is large when the electronic devices are working. The structure of the case using the side wall to achieve natural heat dissipation is difficult to meet the heat dissipation requirements of the electronic devices.

[0003] Most of the existing forced air cooling cases increase the heat dissipation efficiency by allowing air to flow through the gaps between the electronic modules to take away the heat of the electronic modules. However, in this way, the inside of the case is not completely sealed, which makes it difficult to ensure the sealing requirements of the electronic components. Some cases separate the air ducts from the electronic components, and usually adopt structures such as front air inlet and rear air outlet, left air inlet and right air outlet, or upper air inlet and lower air outlet. For example, the patent document with the patent application number "CN202211363543.0" discloses a forced air cooling sealed case. The case body is formed by surrounding each plate. The excessive sealing connection method makes the assembly complex, and it is difficult to ensure the sealing effect between the plates, which greatly reduces the sealing performance of the case body. Moreover, the air outlet of the heat dissipation air duct is arranged on one side of the upper heat conduction plate and the lower heat conduction plate extending out of the partition plate. The direction of the air inlet and the air outlet of the heat dissipation air duct is bent. When the air flow in the heat dissipation air duct flows, it may backflow due to the blockage of the edge of the heat conduction plate. The tortuous heat dissipation air duct in the case increases the air resistance, and the air flow at the side of the case body flows faster, making it difficult to dissipate heat at the center position and reducing the heat dissipation efficiency. SUMMARY

DETAILED DESCRIPTION

[0030] With reference to the drawings, the specific implementation of the utility model will be described in detail.

[0031] With reference to Figs. 1 to 4 The utility model provides a kind of air cooling machine case cabinet of air cooling machine case.

[0032] An air cooling machine case, comprising frame body 100, rear cover body 400, wherein the frame body 100 is made of heat-conducting material, the frame body 100 has at least one module mounting cavity 110 with front and rear openings, the front opening of the module mounting cavity 110 is sealingly connected with a front panel 700, and the module mounting cavity 110 is used for mounting electronic modules. Further, the front side of the module mounting cavity 110 is provided with a sealing groove 180, and a sealing ring is arranged in the sealing groove 180. It can be understood that the front panel 700 can be detachably connected by bolts or mounted by other limiting structures, such as buckles and the like, which are not limited herein as long as the front panel 700 can be mounted.

[0033] Further, a plurality of module slots 111 are arranged on the upper and lower sidewalls of the module mounting cavity 110, and electronic modules can be inserted into the module slots 111 by locking members. At this time, the heat generated by the electronic modules is transmitted to the slot wall through the locking members, and then dissipated through the frame body 100. Preferably, a plurality of waist-shaped grooves are formed on the left and right sidewalls of the frame body 100. In this way, the heat dissipation area of the frame body 100 is increased, and the strength of the frame body 100 is ensured.

[0034] The upper and lower sides of the frame 100 are provided with an upper cover plate 200 and a lower cover plate 300. The upper cover plate 200 is arranged on the top of the frame 100 and has a gap between the upper cover plate 200 and the top wall of the frame 100 as an upper air duct. The lower cover plate 300 is arranged on the bottom of the frame 100 and has a gap between the lower cover plate 300 and the bottom wall of the frame 100 as a lower air duct. The electronic modules in the cabinet are cooled by the upper air duct and the lower air duct.

[0035] The rear cover 400 is arranged on the rear side of the frame 100 and seals the rear opening of the module mounting cavity 110 through a sealing structure. The sealing structure can be matched by a sealing groove 180 and a sealing ring. The sealing groove 180 can be arranged on the rear cover 400 or the frame 100. In this embodiment, the front and rear sides of the module mounting cavity 110 are both provided with the sealing groove 180, and the sealing ring is arranged in the sealing groove 180. During assembly, the front panel 700 presses the sealing ring in the sealing groove 180 on the front side of the frame 100 to seal the front side of the module mounting cavity 110, and the edge of the rear cover 400 presses the sealing ring on the rear side of the module mounting cavity 110 to seal the rear opening of the module mounting cavity 110.

[0036] The rear cover 400 is provided with a first partition plate 410 to divide the rear cover 400 into a circuit board mounting cavity 420 and a heat dissipation cavity 430 which are in communication with the module mounting cavity 110. The upper and lower sides of the first partition plate 410 are respectively provided with a plurality of ventilation holes 440 which are in communication with the upper air duct and the lower air duct. The ventilation holes 440 are staggered with the circuit board mounting cavity 420 and are in communication with the heat dissipation cavity 430. At this time, the circuit board mounting cavity 420 is used for mounting circuit boards and other components, and the module mounting cavity 110 is used for inserting electronic modules. The heat flow of the air duct directly enters the heat dissipation cavity 430 through the partition plate without passing through the circuit board mounting cavity 420 and the module mounting cavity 110, thereby ensuring the sealing of the electronic modules in the cabinet.

[0037] Further, the rear cover plate 500 is arranged on the rear side of the rear cover 400 and has a plurality of air outlets 510 which are in communication with the heat dissipation cavity 430. The air cooling assembly 600 is arranged in the heat dissipation cavity 430. Specifically, the air cooling assembly 600 includes a fan which is installed in the heat dissipation cavity 430 through a mounting bracket. At this time, under the drive of the fan, fresh air enters the heat dissipation cavity 430 from the air inlet 140 of the air duct through the ventilation holes 440 and is discharged from the air outlets 510 to dissipate heat from the cabinet.

[0038] Further, the middle part of the heat dissipation cavity 430 is surrounded by a second partition plate 450 to form a plug-in mounting cavity 460. The mounting part of the air cooling assembly 600 and the plug-in mounting position are separated by the second partition plate 450, so that the airflow does not pass through the plug-in mounting cavity 460, thereby ensuring the sealing of the electronic components.

[0039] In some embodiments, the top of the frame 100 is concave downward to form an upper groove 120, and the upper groove 120 and the upper cover plate 200 form the upper air duct. The bottom of the frame 100 is concave upward to form a lower groove 130, and the lower groove 130 and the lower cover plate 300 form the lower air duct. The front side of the upper groove 120 and the lower groove 130 has a plurality of air inlets 140, and the rear side has a plurality of air guide outlets 150 with an axis parallel to the axis of the air inlets 140 and a flow guide 160 inclined to the air guide outlets 150. The air guide outlets 150 correspond to the ventilation holes 440. At this time, the air guide outlets 150 arranged on the rear side of the upper groove 120 and the lower groove 130 guide the airflow in the air duct to the ventilation holes 440 and then into the heat dissipation cavity 430. The flow guide 160 is used to guide the airflow in the air duct so that it can quickly flow to the ventilation holes 440, thereby improving the heat dissipation efficiency.

[0040] Further, the rear side of the upper groove 120 and the lower groove 130 is provided with two groups of air guide outlets 150 distributed on the left and right sides of the upper groove 120 and the lower groove 130. The flow guide 160 is arranged between the two groups of air guide outlets 150 and has two flow guide surfaces 161 inclined to the air guide outlets 150 on both sides of the center. At this time, the air guide outlets 150 are arranged on both sides of the upper groove 120 and the lower groove 130 to discharge the airflow to both sides of the air duct. The two flow guide surfaces 161 of the flow guide 160 guide the airflow to both sides to avoid heat accumulation in the middle of the box.

[0041] In some embodiments, the frame 100 further comprises heat dissipation fins 170 arranged in the upper groove 120 and the lower groove 130. The heat dissipation fins 170 extend in the front-rear direction of the frame 100, and the adjacent two heat dissipation fins 170 form a sub-air duct. At this time, the arrangement of the heat dissipation fins 170 can increase the contact area between the frame 100 and the airflow, thereby improving the heat dissipation efficiency. Further, the upper cover plate 200 is arranged on the opening side of the upper groove 120 by a bolt cover, the lower cover plate 300 is arranged on the opening side of the lower groove 130 by a bolt cover, and the heat dissipation fins 170 are integrally formed between the upper and lower walls of the frame 100. Heat can be transferred from the frame 100 to the heat dissipation fins 170 and then contact with fresh air for air cooling.

[0042] Preferably, the heat dissipation fins 170 include straight sections 171 and inclined sections 172, which are arranged at the rear side of the upper groove 120 and the lower groove 130 and inclined to the direction of the air vents 440. At this time, the air flow is guided to the air outlets 150 on both sides of the upper groove 120 and the lower groove 130 by the shape of the heat dissipation fins 170, and cooperates with the cooperation of the flow guide 160, so that the air flow in the air duct quickly flows to both sides and is discharged from the air vents 440, avoiding the accumulation of heat in the middle of the upper and lower sides of the frame 100. Further, the lengths of the plurality of inclined sections 172 gradually increase from the center to both sides. At this time, the greater the length of the inclined section 172, the greater the air resistance of the air outlet of the sub-air duct. Since the air vents 440 are arranged on both sides of the rear cover, under the action of the air cooling assembly 600, the air flow is more easily sucked into and discharged from the sub-air duct close to the air vent 440. By using the above method, the air resistance of each sub-air duct gradually increases from the center to both sides. The air resistance of the sub-air duct close to the air vent 440 is greater, and the air resistance of the air outlet of the sub-air duct close to the center of the frame 100 is smaller, thereby forcing the air flow in the air duct to flow in the sub-air duct in the middle of the frame 100, so that the air flow of each sub-air duct can flow uniformly, improving the heat dissipation efficiency. Similarly, the inclination angle of each inclined section 172 can be set as needed. For example, by setting the inclination angle, the size of the air outlet of each sub-air duct is limited from inside to outside. Of course, the size of the air outlet of the sub-air duct close to the air vent 440 can also be designed. The smaller the opening of the air outlet of the sub-air duct, the greater the air resistance, which can also force the air flow to flow in the sub-air duct in the middle of the frame 100, uniformly the air flow of each sub-air duct, and improve the heat dissipation efficiency.

[0043] In some embodiments, two module mounting cavities 110 are provided, and the size of each module mounting cavity 110 can be designed as needed, which is not limited herein. The front panel 700 of one of the module mounting cavities 110 is bolted to the front side of the frame 100, and the bottom of the front panel 700 of the other module mounting cavity 110 is hingedly arranged on the frame 100. The top of the front panel 700 is connected with a knob 720 through a bearing. The outer periphery of the knob 720 is provided with a clamping column 721, and the front side wall of the frame 100 is provided with a clamping block 730 having a clamping groove 731 matched with the clamping column 721. When the knob 720 rotates, the clamping column 721 is rotated into or out of the clamping groove 731. In this way, one of the module mounting cavities 110 provided with the knob 720 on the front panel 700 can be quickly opened or closed, facilitating the quick insertion and extraction of electronic modules. When it is needed to open the module mounting cavity 110, the knob 720 is rotated to drive the clamping column 721 to rotate out of the clamping groove 731 to unlock the upper side of the front panel, and then the front panel 700 is flipped down to open the front panel 700. Further, the front side of the frame 100 is also provided with a mounting cavity, and a photoelectric switch is arranged in the mounting cavity to detect the opening and closing of the front panel 700.
