Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to an air compressor with a cooling mechanism. Background Art

[0002] An air compressor, also known as an air compressor, is a mechanical device used to compress gas. It reduces the volume of air through various mechanical principles, thereby increasing the pressure of the air.

[0003] Reference is made to the utility model patent with authorized publication number CN213392572U, which discloses an air compressor with a built-in cooling system. The air compressor includes a cylinder head, a valve plate and a cylinder body. The cylinder head is provided with a cylinder head cooling water channel, the cylinder body is provided with a cylinder body cooling water channel, the valve plate is provided with a valve plate cooling water channel, and the cylinder body cooling water channel, the valve plate cooling water channel and the cylinder head cooling water channel are connected in sequence.

[0004] The above patent has the following defects in practical application: the above patent adopts a design that is integrated with the air compressor, and multiple cooling water channels are opened on the air compressor cylinder body, which has great difficulty in actual casting and mold opening processes, high production costs, and high actual production and use costs. At the same time, too many cooling water channels are opened on the compressor cylinder body, which has a relatively obvious reduction in the strength of the air compressor cylinder body, which is not conducive to the stable operation of the air compressor. Therefore, the above design is not practical. In order to solve the above technical defects, we propose an air compressor with its own cooling mechanism. Utility Model Content

[0005] The utility model aims to solve the shortcomings of the prior art and proposes an air compressor with a self-cooling mechanism.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An air compressor with a built-in cooling mechanism comprises an air compressor and an external cooling mechanism; the external cooling mechanism comprises two symmetrically arranged shell covers, the two sides of the shell covers are symmetrically fixedly connected with mounting blocks, the mounting blocks are screwed with bolts, the upper side of the shell covers is fixedly connected with a water inlet pipe, the lower side of the shell covers is fixedly connected with a water outlet pipe, the outer side of the water outlet pipe is connected with a return water ring cavity, the side of the return water ring cavity is installed with a heat dissipation cavity, the upper end of the water inlet pipe is connected with a pressure equalizing water tray, the side of the heat dissipation cavity is connected with a water tank, the upper side of the water tank is fixedly installed with a water pump, the water pump is connected with a water supply pipe, and the water supply pipe is connected to the upper side of the pressure equalizing water tray.

[0009] Preferably, a heat dissipation cavity wall is arranged on the outside of the air compressor, the two shell cover threaded sleeves are arranged on the outside of the heat dissipation cavity wall, a sealing ring is arranged at the contact between the shell cover and the heat dissipation cavity wall, and a sealing gasket is arranged at the junction of the two shell covers.

[0010] Preferably, four water inlet pipes are evenly distributed along the upper side of the shell cover.

[0011] Preferably, an external threaded connector is rotatably mounted on the upper end of the water inlet pipe, and the water inlet pipe is threadedly connected to the bottom of the pressure equalizing water tray via the external threaded connector.

[0012] Preferably, an internal threaded barrel is rotatably mounted on the inner side of the water return annular cavity, and the internal threaded barrel is threadedly connected to the water outlet pipe.

[0014] Preferably, the water pumping end of the water pump extends to the bottom of the water tank, and a water inlet is provided on the water tank.

[0015] Compared with the related art, the air compressor with a self-cooling mechanism proposed by the utility model has the following beneficial effects:

[0016] In the utility model, an air compressor with a self-contained cooling mechanism is provided with an external cooling mechanism, and two shell covers are screwed and sleeved on the outside of the air compressor, so that a sealed space is formed on the outside of the heat dissipation cavity wall of the air compressor, and water in the water tank is pumped out by a water pump, and the water flow path is a water pump working chamber, a water delivery pipe, a pressure equalizing water tray and a water inlet pipe, a shell cover inner cavity, a water outlet pipe, a water return annular cavity, a heat dissipation cavity, and finally flows back to the water tank to form a cycle, and when the water flows into the shell cover inner cavity, the heat dissipation cavity wall is cooled, thereby achieving the cooling effect on the air compressor, and flows back to the heat dissipation cavity through the lower side return annular cavity. The water temperature in the heat dissipation cavity is relatively high, the heat dissipation cavity is flat, and its inner and outer walls are fin-shaped, which can fully increase the contact area between the outer wall and the air. When the water flows into the heat dissipation cavity, the heat dissipation cavity will quickly transfer the temperature in the water flow to the outside, thereby achieving the heat dissipation and cooling effect on the water flow. Finally, the water flowing back into the water tank can continue to be used as cooling water. The external cooling mechanism in the utility model adopts a design that is separated from the air compressor body, so that the external cooling mechanism only cools the air compressor and will not interfere with the main operation of the air compressor. Moreover, the entire external cooling mechanism can be flexibly disassembled and installed, and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0023] Reference Figure 1-4 , please refer to Figure 1-Figure 4 ,in, Figure 1 This is a three-dimensional structural schematic diagram of an air compressor with a built-in cooling mechanism proposed by the utility model; Figure 2 It is a partial three-dimensional structural schematic diagram of an air compressor with a self-cooling mechanism proposed by the utility model; Figure 3 This is a schematic diagram of the disassembled three-dimensional structure of an air compressor with a cooling mechanism proposed by the utility model Figure 1 ; Figure 4 This is a schematic diagram of the disassembled three-dimensional structure of an air compressor with a cooling mechanism proposed by the utility model Figure 2 An air compressor with a built-in cooling mechanism comprises: an air compressor 1 and an external cooling mechanism; the external cooling mechanism comprises two symmetrically arranged shell covers 2, the two sides of the shell covers 2 are symmetrically fixedly connected with mounting blocks 3, the mounting blocks 3 are screwed with bolts 4, the upper side of the shell cover 2 is fixedly connected with a water inlet pipe 7, the lower side of the shell cover 2 is fixedly connected with a water outlet pipe 5, the outer side of the water outlet pipe 5 is connected with a return water ring cavity 6, the side of the return water ring cavity 6 is installed with a heat dissipation cavity 9, the upper end of the water inlet pipe 7 is connected with a pressure equalizing water pan 8, the side of the heat dissipation cavity 9 is connected with a water tank 10, the upper side of the water tank 10 is fixedly installed with a water pump 11, the water pump 11 is connected with a water delivery pipe 12, the water delivery pipe 12 is connected to the upper side of the pressure equalizing water pan 8, the water pumping end of the water pump 11 extends to the bottom of the water tank 10, and the water tank 10 is provided with a water inlet 14.

[0024] By setting in the above manner, when installing the shell cover 2, the two shell covers 2 are symmetrically sleeved on the outside of the air compressor 1, and the bolts 4 are inserted and screwed on the mounting block 3, so that the two shell covers 2 form a whole and form a sealed chamber with the outer wall of the air compressor 1. Subsequently, cooling water is introduced to dissipate heat for the air compressor 1. Compared with the traditional air cooling, the heat dissipation efficiency is greatly improved.

[0025] In this embodiment, the inner cavity of the shell 2, the water outlet pipe 5, the water return ring cavity 6, the heat dissipation cavity 9, the water tank 10, the working chamber of the water pump 11, the water delivery pipe 12, the pressure equalizing water tray 8 and the water inlet pipe 7 are interconnected.

[0026] By the arrangement in the above manner, the water pump 11 is started to pump out the water in the water tank 10, and the water flow path is the working chamber of the water pump 11, the water delivery pipe 12, the pressure equalizing water tray 8 and the water inlet pipe 7, the inner cavity of the shell 2, the water outlet pipe 5, the return water ring cavity 6, the heat dissipation cavity 9, and finally flows back to the water tank 10 to form a water circulation.

[0027] In this embodiment, a heat dissipation cavity wall 101 is arranged outside the air compressor 1, two shell covers 2 are threadedly sleeved outside the heat dissipation cavity wall 101, a sealing ring is arranged at the contact between the shell cover 2 and the heat dissipation cavity wall 101, and a sealing gasket 13 is arranged at the intersection of the two shell covers 2.

[0028] By the above-mentioned arrangement, the sealing ring and the sealing gasket 13 are arranged so that all contact points of the chamber formed between the two shell covers 2 and the heat dissipation cavity wall 101 on the side of the air compressor 1 are sealed to avoid water leakage.

[0029] In this embodiment, four water inlet pipes 7 are evenly arranged along the upper side of the shell 2 .

[0030] Through the above-mentioned arrangement, four water inlet pipes 7 are arranged along the shell cover 2, and the upper sides of the two shell covers 2 have a total of eight water inlets, so that the water inlet ends are evenly distributed on the upper sides of the shell covers 2, thereby making the water flow received in the shell cover 2 more evenly distributed, and can flow relatively evenly through the outside of the heat dissipation cavity wall 101, thereby making the cooling more uniform.

[0031] In this method, an external threaded connector 701 is rotatably installed on the upper end of the water inlet pipe 7, and the water inlet pipe 7 is screwed to the bottom of the pressure equalizing water tray 8 through the external threaded connector 701. An internal threaded tube 601 is rotatably installed on the inner side of the return water ring cavity 6, and the internal threaded tube 601 is screwed to the water outlet pipe 5.

[0032] Through the above-mentioned arrangement, the connection modes of the water inlet pipe 7 and the water outlet pipe 5 are both detachable screw connections, which provides convenience for disassembly and installation.

[0033] In this embodiment, the outer wall and the inner cavity of the heat dissipation cavity 9 are evenly provided with fin-shaped protrusions.

[0034] Through the above-mentioned arrangement, the arrangement of the fin-shaped protrusions on the inner side of the heat dissipation cavity 9 increases the contact area between the water flowing through the heat dissipation cavity 9 and the inner wall of the heat dissipation cavity 9, thereby expanding the contact heat dissipation path of the water flow. The arrangement of the fin-shaped protrusions on the outer side of the heat dissipation cavity 9 increases the contact area between the heat dissipation cavity 9 and the air, so that the outer wall of the heat dissipation cavity 9 can more quickly transfer the heat received on the inner wall to the air.

[0035] The working principle of an air compressor with a self-cooling mechanism provided by the utility model is as follows:

[0036] When in use, when the air compressor 1 is working, the water pump 11 is started synchronously, and the water pumping end of the water pump 11 delivers the cooling water in the water tank 10 to the inside of the pressure equalizing water tray 8 through the water delivery pipe 12. The water flows through the water inlet pipe 7 at the bottom of the pressure equalizing water tray 8 and is divided into eight water flow paths to enter the sealed chamber inside the shell cover 2. The water flows evenly cool the heat dissipation cavity wall 101, and the heat dissipation cavity wall 101 transfers the temperature generated when the air compressor is working to the water flow, thereby achieving the cooling effect on the air compressor 1. After the water flow has a cooling effect, it passes through the lower The water outlet pipe 5 on the side enters the return water ring cavity 6, and then flows back to the heat dissipation cavity 9. The heat dissipation cavity 9 dissipates the temperature in the water flow into the external air, thereby achieving the heat dissipation and cooling effect on the water flow. Finally, the water flow returning to the water tank 10 can continue to be used as cooling water. The utility model adopts a design in which an external cooling mechanism is separated from the main body of the air compressor 1, so that the external cooling mechanism only cools the air compressor 1, does not interfere with the main operation of the air compressor 1, and the entire external cooling mechanism can be flexibly disassembled and installed, and is highly practical.

Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
