Description

Technical Field

[0001] The utility model relates to the field of screw air compressor cooling, in particular to a cooling structure of a screw air compressor. Background Art

[0002] The screw air compressor adopts pre-packaged configuration. The screw air compressor only requires a single power connection and compressed air connection. The screw compression component in the screw air compressor is manufactured in-house using the latest CNC grinding machines and combined with online laser technology to ensure extremely precise manufacturing tolerances. Its reliability and performance can ensure that the operating costs of the compressor are extremely low during its service life.

[0003] In the prior art, when a screw air compressor is in use, due to the excessive number of internal structures, the free space inside the screw air compressor case is too small. When the screw air compressor is used for a long time, the heat generated will fill the entire narrow space. The existing case internal heat dissipation only uses heat dissipation holes, heat dissipation fins or guide fans to discharge the heat to the outside of the case. When heat dissipation holes are used in conjunction with heat dissipation fans, the heat can only be dissipated in one direction, and the interior of the screw air compressor cannot be fully cooled. When heat dissipation is performed using heat dissipation fins, the heat dissipation fins are also in a fixed state. Once damaged, they cannot be disassembled and replaced in time, which is inconvenient to use.

[0004] Therefore, it is necessary to invent a cooling structure for a screw air compressor. Utility Model Content

[0005] The purpose of this utility model is to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a cooling structure for a screw air compressor, comprising a chassis, a storage tank is provided on one side of the outer end of the chassis, a heat exchange component is provided on the inner side of the chassis, cooling fins are fixedly installed on the sides of both ends of the chassis, and limiting components are installed at intervals on the surfaces of both ends of the chassis.

[0007] Based on the above characteristics: coolant is set inside the storage tank, the outer shell of the screw air compressor is the chassis, and the screw compression component is located in the inner cavity of the chassis. When the inner cavity of the chassis is overheated, the coolant inside the storage tank can be extracted and then transported to the heat exchange component. Since the heat exchange component is located inside the chassis, the heat at various positions of the chassis will be absorbed and exchanged by the heat exchange component. At the same time, the heat dissipation fins can also assist in dissipating the heat. Finally, the coolant after heat exchange will flow back to the storage tank and wait for the next use.

[0008] Preferably, the chassis includes end panels and side panels, the end panels and side panels are in a concave-shaped structure, and the inner wall surfaces of the end panels and side panels are provided with through holes in a rectangular array.

[0009] Based on the above features: the end plates are located at the upper and lower ends of the side plates, and the interior of the end plates and side plates is a hollow structure, which is convenient for the installation of heat exchange components inside. When the heat in the chassis cavity is too high, the heat will be quickly absorbed and exchanged by the heat exchange components through the through holes.

[0010] Preferably, positioning plates are fixedly mounted on both ends of the outer wall of the end plate, a movable slot is provided on the surface of the end plate, and a heat conduction hole is provided on the bottom surface of the movable slot.

[0011] Based on the above features: one end of the heat sink is plugged into the inner side of the movable slot. When the heat inside the chassis is too high, the heat can flow through the through-holes and the heat conduction holes, so that the heat can be quickly absorbed and discharged by the heat sink.

[0012] Preferably, a filling port is installed on one side of the upper end of the storage tank, a return pump is provided on the upper end of the storage tank, and a suction pump is installed on one side of the lower end of the storage tank.

[0013] Based on the above features: the coolant can be added to the storage tank through the filling port, the water outlet pipe is located on the lower side, and is opened and closed by a valve, which is not drawn in this application. It is hereby explained that the suction pump can extract the coolant in the storage tank, and the return pump can pump the coolant after heat exchange back into the storage tank.

[0014] Preferably, the heat exchange assembly includes a drain pipe and a water inlet pipe, and a hot water exchange pipe is connected between the drain pipe and the water inlet pipe.

[0015] Based on the above characteristics: one end of the drainage pipe is connected to the water inlet end of the return pump, the other end of the drainage pipe is connected to one end of the hot water exchange pipe, one end of the water inlet pipe is connected to the drainage end of the suction pump, and the other end of the water inlet pipe is connected to the hot water exchange pipe. Since the hot water exchange pipe is arranged on the inner side of the end plate and the side plate, it is convenient for the hot water exchange pipe to perform all-round heat exchange from the side or the upper and lower ends.

[0016] Preferably, a fixed plug-in plate is fixedly mounted on one end of the heat dissipation fin, the heat dissipation fin and the fixed plug-in plate are an integrated structure, and the heat dissipation fin and the fixed plug-in plate are in a T-shaped structure.

[0017] Based on the above features: the heat sink fins are plugged into the inner side of the movable slots through fixed plug-in plates, which makes it convenient for the heat sink fins to absorb and dissipate heat, and can also be movably disassembled and replaced.

[0018] Preferably, the limiting assembly includes an L-shaped fixing plate and a buffer spring installed on the inner side of the L-shaped fixing plate, and a baffle is installed on the upper end of the buffer spring.

[0019] Based on the above features: when the buffer spring drives the baffle to extend outward, the baffle will be limited by the positioning plate to prevent the baffle from separating from the L-shaped fixing plate. At this time, the installed heat dissipation fins cannot be separated from the movable slots. When the baffle is pressed back to the inside of the L-shaped fixing plate, the heat dissipation fins can be pulled out from the inside of the movable slots.

[0020] The beneficial effects of the utility model are:

[0021] 1. When the inner cavity of the chassis is overheated, the suction pump can extract the coolant in the storage tank and then introduce it into the hot water exchange pipe through the water inlet pipe. At this time, the heat in the chassis will contact the hot water exchange pipe through the through hole, so that the hot water exchange pipe can exchange heat in all directions from the side or upper and lower ends of the chassis. At the same time, the heat dissipation fins can also assist in dissipating heat, which facilitates rapid cooling inside the screw air compressor chassis.

[0022] 2. The heat sink fins can be detached and assembled. The heat sink fins are inserted into the inner side of the movable slots through the fixed plug-in plate. When installing, first press the baffle back to the inner side of the L-shaped fixed plate, then insert the heat sink fins into the inner side of the movable slots through the fixed plug-in plate, and finally release the baffle to make the baffle rebound to limit the two sides of the fixed plug-in plate. At this time, the heat in the chassis can be dissipated through the through holes and thermal holes, and then the heat will be quickly conducted out by the heat sink fins.

[0030] Coolant is provided inside the storage tank 2. The outer shell of the screw air compressor is the chassis 1. The screw compression assembly is located in the inner cavity of the chassis 1. When the inner cavity of the chassis 1 is overheated, the coolant inside the storage tank 2 can be extracted and then transported to the heat exchange assembly 3. Since the heat exchange assembly 3 is located inside the chassis 1, the heat at various positions of the chassis 1 will be adsorbed and exchanged by the heat exchange assembly 3. At the same time, the heat dissipation fins 4 can also assist in discharging the heat. The heat dissipation fins 4 can be movably disassembled and assembled, and the limit assembly 5 can limit the two sides of the heat dissipation fins 4 to prevent the heat dissipation fins 4 from separating after installation. Finally, the coolant after heat exchange will flow back to the storage tank 2 and wait for the next use.

[0031] Preferably, the chassis 1 includes an end plate 11 and a side plate 12 . The end plate 11 and the side plate 12 are in a concave-shaped structure. A rectangular array of through holes 13 is provided on the inner wall surfaces of the end plate 11 and the side plate 12 .

[0032] The end plate 11 is located at the upper and lower ends of the side plate 12. The interior of the end plate 11 and the side plate 12 is a hollow structure, which is convenient for the heat exchange component 3 to be installed inside. When the heat in the inner cavity of the chassis 1 is too high, the heat will be quickly absorbed and exchanged by the heat exchange component 3 through the through hole 13.

[0033] Preferably, positioning plates 111 are fixedly mounted on both ends of the outer wall of the end plate 11 , a movable slot 112 is provided on the surface of the end plate 11 , and a heat conducting hole 113 is provided on the bottom surface of the movable slot 112 .

[0034] One end of the heat sink 4 is inserted into the inner side of the movable slot 112. When the heat in the inner cavity of the chassis 1 is too high, the heat can flow through the through hole 13 and the heat conducting hole 113, so that the heat is quickly absorbed and discharged by the heat sink 4. When the heat sink 4 is removed, the heat can also be dissipated through the through hole 13 and the heat conducting hole 113.

[0035] Preferably, a filling port 21 is installed on one side of the upper end of the storage tank 2 , a return pump 22 is provided on the upper end of the storage tank 2 , and a suction pump 23 is installed on one side of the lower end of the storage tank 2 .

[0036] The coolant can be added to the storage tank 2 through the filling port 21. The water outlet pipe is located on the lower side and is opened and closed by a valve. It is not drawn in this application.

One end of the water inlet pipe 32 is connected to the drainage end of the suction pump 23, and the other end of the water inlet pipe 32 is connected to the hot water exchange pipe 33. Since the hot water exchange pipe 33 is arranged on the inner side of the end plate 11 and the side plate 12, it is convenient for the hot water exchange pipe 33 to perform all-round heat exchange from the side or the upper and lower ends.

[0040] The heat dissipation fins 4 are plugged into the inner side of the movable slots 112 via the fixed plug-in plates 41 , which facilitates the heat dissipation and absorption of the heat by the heat dissipation fins 4 and allows for movable assembly and disassembly for replacement.

[0041] Preferably, the limiting assembly 5 includes an L-shaped fixing plate 51 and a buffer spring 52 installed on the inner side of the L-shaped fixing plate 51 , and a baffle 53 is installed on the upper end of the buffer spring 52 .

[0042] The baffle 53 is limited on the inner side of the L-shaped fixed plate 51, and the buffer spring 52 can make the baffle 53 telescopic and adjustable. When the buffer spring 52 drives the baffle 53 to extend outward, the baffle 53 will be limited by the positioning plate 111 to prevent the baffle 53 from being separated from the L-shaped fixed plate 51. At this time, the installed heat dissipation fins 4 cannot be separated from the movable slots 112. When the baffle 53 is pressed to retract to the inner side of the L-shaped fixed plate 51, the heat dissipation fins 4 can be pulled out from the inner side of the movable slots 112.

[0043] The usage process of the present invention is as follows: coolant is provided inside the storage tank 2. When the inner cavity of the chassis 1 is overheated, the suction pump 23 can extract the coolant in the storage tank 2, and then introduce it into the hot water exchange pipe 33 through the water inlet pipe 32. At this time, the heat in the chassis 1 will contact the hot water exchange pipe 33 through the through hole 13 for heat exchange, and the return pump 22 can extract the coolant after heat exchange through the drain pipe 31. The heat dissipation fins 4 are plugged into the inner side of the movable slot 112 through the fixed plug-in plate 41, so that the heat in the chassis 1 can be quickly discharged by the heat dissipation fins 4, and the heat dissipation fins 4 can be movably installed. During installation, first press the baffle 53 to retract it to the inner side of the L-shaped fixed plate 51, then plug the heat dissipation fins 4 into the inner side of the movable slot 112 through the fixed plug-in plate 41, and finally release the baffle 53 to make the baffle 53 rebound to limit the two sides of the fixed plug-in plate 41.
