Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology, and specifically discloses a compressor heat dissipation structure. Background Technology

[0002] The GM series compressors have a small internal space and are equipped with multiple electrical control systems. During operation, the internal electronic components generate a lot of heat, which needs to be dissipated in time; otherwise, it will cause high-temperature shutdown and damage to electronic components.

[0003] Currently, GM series compressors dissipate heat through natural ventilation by adding heat dissipation vents to the side of the casing, but this method is inefficient. Other technologies improve heat dissipation by adding cooling fans to the compressor casing to accelerate airflow; simultaneously, dust cloths or screens are used at the air inlet and outlet to prevent external dust from entering the compressor. While these methods are effective at preventing dust, the small mesh size of the dust screens allows dust to adhere and impede ventilation, further reducing heat dissipation. Utility Model Content

[0004] The purpose of this invention is to solve the above problems and provide a compressor heat dissipation structure that can achieve good heat dissipation and reduce dust entering the compressor.

[0005] The purpose of this utility model is achieved through the following technical solution: a compressor heat dissipation structure, including an air inlet mechanism and an air outlet mechanism disposed on opposite two shell walls of the compressor housing, wherein air enters the interior of the compressor housing from the air inlet mechanism and is discharged from the air outlet mechanism;

[0006] The air intake mechanism includes:

[0007] An air inlet shroud is disposed on the outer wall of the compressor housing and forms a buffer cavity between the air inlet shroud and the compressor housing. A deposition area is formed in the lower part of the buffer cavity. The air inlet of the compressor housing is connected to the upper part of the buffer cavity. An air inlet shroud opening is provided in the middle of the air inlet shroud.

[0008] Several dustproof blade assemblies are installed sequentially from top to bottom in the air inlet hood opening, and an air inlet channel communicating with the buffer chamber is formed between two adjacent dustproof blade assemblies.

[0009] This invention forms a buffer chamber within the air intake mechanism. After the air enters the buffer chamber, the flow rate slows down, and the dust in the air settles to the deposition area at the bottom of the buffer chamber. At the same time, the air inlet of the compressor housing is connected to the upper part of the buffer chamber. The air entering the buffer chamber needs to flow upward to enter the compressor housing from the air inlet. During this process, it is not easy to carry down the dust, thereby reducing the amount of dust entering the compressor housing.

[0010] The buffer chamber is provided with a dust baffle plate located below the opening of the air inlet hood. One end of the dust baffle plate is connected to the inner wall of the air inlet hood, and the other end is inclined downward to form a dust collection groove between the dust baffle plate and the outer wall of the compressor housing. The dust collection groove is connected to the deposition area located below the dust baffle plate.

[0011] Dust baffles can prevent dust in the deposition area from rising, and the inclined dust baffles can prevent dust from accumulating on the surface of the dust baffles.

[0012] The bottom of the sedimentation zone is equipped with a detachable dust removal plate to facilitate the removal of dust from the sedimentation zone.

[0013] The dustproof blade assembly includes a dustproof blade whose upper end is fixed to the side wall of the air inlet hood opening and whose lower end is inclined downwards towards the outside of the buffer cavity. A horizontal plate is connected to the upper end of the dustproof blade via an arc segment. The horizontal plate extends horizontally outwards from the buffer cavity and forms the air inlet channel between itself and the dustproof blade of the dustproof blade assembly above it. The lower end of the dustproof blade of the upper dustproof blade assembly is lower than the height of the horizontal plate of the lower dustproof blade assembly. The arc segment and the horizontal plate can, to a certain extent, block external dust particles from entering the buffer cavity, further improving the dustproof effect.

[0014] The air outlet mechanism includes an air outlet cover disposed on the outer wall of the compressor housing, a fan installed inside the air outlet cover, and several ventilation blades installed sequentially from top to bottom on the opening of the air outlet cover; the air outlet of the compressor housing is connected to the air outlet cover.

[0015] The ventilation blades are rotatably mounted on the opening of the air outlet hood via a shaft. The upper and lower adjacent ventilation blades overlap at the ends to close the opening of the air outlet hood when not ventilated, preventing external dust from entering the compressor housing from the air outlet mechanism.

[0016] The air outlet shroud is provided with a partition that divides its internal space into several fan mounting cavities; each fan mounting cavity is equipped with a fan.

[0017] Compared with the prior art, this application has the following beneficial effects:

[0018] (1) The air intake mechanism of this utility model prevents external dust from entering the compressor housing by blocking and settling. It can ensure that the air intake channel is unobstructed while intercepting external dust, thus achieving a good heat dissipation and dust prevention effect.

[0019] (2) When the fan is not turned on, the ventilation blades of the air outlet mechanism of this utility model can close the opening of the air outlet cover to prevent external dust from entering the compressor housing from the air outlet mechanism.

[0033] Example

[0034] like Figure 1 , 2As shown, this embodiment discloses a compressor heat dissipation structure, including an air inlet mechanism 300 and an air outlet mechanism 200 disposed on opposite walls of a compressor housing 100. Air enters the compressor housing 100 through the air inlet mechanism 300 and exits through the air outlet mechanism 200. In this configuration, the compressor housing 100 has an air inlet 120 and an air outlet 110 on its walls. The air inlet 120 is connected to the air inlet mechanism 300, and the air outlet 110 is connected to the air outlet mechanism 200. The air inlet mechanism 300 is located at the lower part of the compressor housing 100, and the air outlet mechanism 200 is located at the upper part of the compressor housing 100. Fresh air enters the compressor housing 100 through the air inlet mechanism 300 and flows upwards, cooling the electronic components inside the compressor housing 100. The hot air is then discharged through the air outlet mechanism 200.

[0035] like Figure 4 As shown, the air intake mechanism 300 includes an air intake hood 310 and several dustproof blade assemblies 350. The air intake hood 310 has flanges 220 around its perimeter. During installation, screws are used to fix the flanges 220 to the outer wall of the compressor housing 100, thus mounting the entire air intake hood 310 onto the outer wall of the compressor housing 100. Mounting the air intake hood 310 on the outer wall of the compressor housing 100 avoids occupying internal space within the compressor housing 100.

[0036] When the air inlet shroud 310 is installed on the outer wall of the compressor housing 100, a buffer cavity 320 is formed between the housing wall of the compressor housing 100 and the interior of the air inlet shroud 310, and a deposition area 330 is formed at the lower part of the buffer cavity 320. The air inlet 120 of the compressor housing 100 is connected to the upper part of the buffer cavity 320, and an air inlet shroud opening 340 is provided in the middle of the air inlet shroud 310.

[0037] The dustproof blade assembly 350 is installed sequentially from top to bottom on the air inlet hood opening 340. Specifically, the two sides of the dustproof blade assembly 350 are fixedly installed on the two side walls of the air inlet hood opening 340 by screws, and an air inlet channel 360 communicating with the buffer chamber 320 is formed between two adjacent dustproof blade assemblies 350.

[0038] With the above structure, after the air outlet mechanism 200 extracts the hot air from the compressor housing 100, outside air is replenished into the compressor housing 100 through the air inlet mechanism 300. Specifically, outside air enters the buffer chamber 320 through the air inlet channel 360. Since the space of the buffer chamber 320 is larger than the air inlet channel 360, and due to the obstruction of the compressor housing 100 shell wall, the airflow velocity slows down after entering the buffer chamber 320, and the dust in the air settles to the deposition area 330 at the bottom of the buffer chamber 320. In addition, because the air inlet 120 of the compressor housing 100 is connected to the upper part of the buffer chamber 320, the air entering the buffer chamber 320 needs to flow upward to enter the compressor housing 100 through the air inlet 120. During this process, it is not easy to carry down the dust, thereby reducing the amount of dust entering the compressor housing 100.

[0039] In addition, a dust baffle 380 is provided inside the buffer chamber 320, located below the air inlet hood opening 340. Specifically, one end of the dust baffle 380 is connected to the inner wall of the air inlet hood 310, and the other end extends towards the compressor housing 100 shell wall and is inclined downwards. At the same time, a dust collection trough 390 is formed between the lower end of the dust baffle 380 and the shell wall of the compressor housing 100. The width of the dust collection trough 390 is 1 / 4 of the width of the buffer chamber 320. The dust collection trough 390 is connected to the deposition area 330 located below the dust baffle 380, and the settled dust can fall into the deposition area 330 through the dust collection trough 390.

[0040] Because the dust baffle 380 is inclined, the falling dust will fall along the dust baffle 380 into the deposition area 330, preventing dust from accumulating on the surface of the dust baffle 380. In addition, because the dust trough 390 is narrow, the dust baffle 380 can prevent dust in the deposition area 330 from rising.

[0041] In specific settings, a dust removal plate 370 can be installed at the bottom of the sedimentation zone 330 by means of screws. The dust in the sedimentation zone 330 can be discharged by removing the dust removal plate 370.

[0042] like Figure 4 As shown, the dustproof blade assembly 350 includes a dustproof blade 353 whose upper end is fixed to the side wall of the air inlet hood opening 340, and whose lower end extends outward and is inclined downward in the buffer cavity 320. A horizontal plate 351 is connected to the upper end of the dustproof blade 353 via an arc segment 352. The horizontal plate 351 extends horizontally outward in the buffer cavity 320 and forms the air inlet channel 360 between itself and the dustproof blade 353 of the dustproof blade assembly 350 above it. The lower end of the dustproof blade 353 of the upper dustproof blade assembly 350 is lower than the height of the horizontal plate 351 of the lower dustproof blade assembly 350. The dustproof blade 353, the arc segment 352, and the horizontal plate 351 are integrally formed.

[0043] With the aforementioned structure of the dustproof blade assembly 350, when air enters from the air inlet mechanism 300, the arc segment 352 and the horizontal plate 351 can, to a certain extent, block external dust particles from entering the buffer chamber 320, further enhancing the dustproof effect. Especially when external wind blows dust from the ground horizontally towards the air inlet mechanism 300, the wind carries dust particles along the dustproof blade 353, which are eventually blocked by the arc segment 352 and the horizontal plate 351 and fall off, preventing external wind from blowing dust particles into the buffer chamber 320. Furthermore, if the external environment is rainy, the above design can also prevent rainwater from entering the buffer chamber 320.

[0044] like Figure 3 As shown, the air outlet mechanism 200 includes an air outlet shroud 210 disposed on the outer wall of the compressor housing 100, a fan 250 installed inside the air outlet shroud 210, and a plurality of ventilation blades 270 installed from top to bottom on the opening of the air outlet shroud 210; the air outlet 110 of the compressor housing 100 is connected to the air outlet shroud 210.

[0045] Specifically, the ventilation blades 270 are rotatably mounted on the opening of the air outlet shroud 210 via shaft 260. The shaft 260 passes through the ventilation blades 270, and its two ends are fixed to both sides of the opening of the air outlet shroud 210. The ventilation blades 270 and shaft 260 are in a clearance fit, allowing the ventilation blades 270 to rotate. Two adjacent ventilation blades 270 overlap at their ends to close the opening of the air outlet shroud 210 when not in a ventilated state. When the fan 250 is turned on, it blows up the ventilation blades 270, opening the opening of the air outlet shroud 210 and expelling hot air from the compressor housing 100. When the fan 250 is turned off, the ventilation blades 270 fall back under their own weight, closing the opening of the air outlet shroud 210 and preventing external dust from entering the compressor housing 100 through the air outlet mechanism 200.

[0046] Similarly, the exhaust shroud 210 can also be mounted on the outer wall of the compressor housing 100 via the flange 220, and its installation method is the same as that of the intake shroud 310. The fan 250 is installed inside the exhaust shroud 210 to avoid occupying the internal space of the compressor.

[0047] As an optional implementation, the air outlet shroud 210 is provided with a partition 240 that divides its internal space into several fan mounting cavities 230; each of the fan mounting cavities 230 is equipped with a fan 250.

[0048] In practice, fan 250 can be powered by an independent power supply. Alternatively, fan 250 can be connected to the compressor's power supply. When connecting, a 24-volt transformer is installed, which is connected to the compressor's input power. The fan and the 24-volt transformer are connected by an air switch to form a complete cooling system.

[0049] This embodiment can ensure that the air intake channel is unobstructed while intercepting external dust, thus achieving a good heat dissipation and dust prevention effect.

[0050] It should be noted that all features disclosed in this specification, or all steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.

[0051] Furthermore, the specific embodiments described above are exemplary.

Those skilled in the art should understand that this utility model specification and its drawings are illustrative and not intended to limit the scope of the claims.
