Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted air compressor technology, and in particular to a liquid-gas separation mechanism. Background Technology

[0002] Currently, vehicle-mounted air compressors generally need to be used in conjunction with a cooling system to cool the air compressor and prevent it from overheating and malfunctioning.

[0003] Most cooling systems used in conjunction with air compressors carry away heat by circulating coolant within the compressor. Therefore, during operation, as the coolant flows and its temperature rises, some of the liquid will vaporize. Combined with the high pressure already present in the delivery pipes, the coolant will become a liquid-gas mixture.

[0004] Therefore, in order to avoid the coolant temperature from getting too high, it is generally necessary to cool the coolant in the gas-liquid mixture state to achieve liquid-gas separation. However, the existing vehicle air compressor cooling devices on the market have low liquid-gas separation efficiency and relatively complex structure, resulting in large size and heavy weight. Consequently, after being installed on the vehicle, they will take up space for other components and affect the vehicle's driving range. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of low liquid-gas separation efficiency and complex structure in the prior art, which result in large size and heavy weight, and to propose a liquid-gas separation mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A liquid-gas separation mechanism includes a connecting body and a separation tank. The separation tank is fixed to the side wall of the connecting body and has a primary separation pipe inside. The side wall of the primary separation pipe has a nozzle. A secondary separation baffle and a tertiary separation pipe are fixedly connected to the inner wall of the connecting body, and the tertiary separation pipe is located inside the secondary separation baffle. A heat dissipation mechanism communicating with the separation tank is provided on the top of the connecting body, and a liquid outlet is connected to the heat dissipation mechanism. An air outlet communicating with the tertiary separation pipe is fixedly connected to the side wall of the connecting body.

[0008] Preferably, the primary separation tube is located inside the upper part of the separation tank; the nozzle is located on the upper surface of the primary separation tube.

[0009] Preferably, the heat dissipation mechanism includes multiple sets of heat sinks and connectors; the multiple sets of heat sinks are connected to each other through connectors, and each set of heat sinks is connected to a heat dissipation pipe; the side wall of the connector is connected to a liquid inlet, and the side of the connector away from the liquid inlet is provided with a liquid storage chamber; the separation tank, the liquid inlet, and the liquid storage chamber are interconnected; the liquid outlet is connected to the liquid storage chamber.

[0010] Preferably, the heat sink is designed in three groups.

[0011] Preferably, it also includes a pressure plate; the pressure plate is fixedly connected to the side wall of the connecting body.

[0012] Preferably, the pressure plate is equipped with a liquid inlet, a pressure gauge, and a sight glass.

[0013] Preferably, a drain valve is also installed on the side wall of the connector.

[0014] Preferably, a filter and a pressure maintaining valve are installed on the air outlet.

[0015] Compared with the prior art, the present invention provides a liquid-gas separation mechanism, which has the following beneficial effects:

[0016] 1. This liquid-gas separation mechanism, through the design of a primary separation pipe, a secondary separation baffle, and a tertiary separation pipe, with the secondary and tertiary separation baffles and the primary separation pipe located on opposite sides of the separation tank, achieves sequential three-stage liquid-gas separation, greatly improving the efficiency of liquid-gas separation. The entire liquid-gas separation mechanism consists of only connecting bodies, separation tanks, and heat dissipation mechanisms, resulting in a simple structure that allows for more stable and long-term operation. Its small size also minimizes the space occupied by other components in the vehicle, and the simple structure results in a lighter weight, further reducing the vehicle's weight and ensuring the vehicle's driving range.

[0017] 2. This liquid-gas separation mechanism achieves high liquid-gas separation efficiency by designing the primary separation pipe inside the upper part of the separation tank and spraying the nozzle towards the inner wall of the top of the separation tank, taking advantage of the greater distance between the liquid at the top and bottom of the separation tank.

[0018] 3. This liquid-gas separation mechanism, through the design of the pressure plate and the fact that both ends of the separation tank are also open, allows the pressure plate to be disassembled for maintenance after long-term operation, thus improving the convenience of maintenance.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model.

Therefore, they should not be construed as limitations on this utility model.

[0030] Example 1:

[0031] Reference Figures 1-4 A liquid-gas separation mechanism includes a connecting body 1 and a separation tank 101. The separation tank 101 is fixed to the side wall of the connecting body 1. There are two sets of connecting bodies 1. The separation tank 101 is fixedly connected in the middle of the two sets of connecting bodies 1. A primary separation pipe 103 is provided inside the separation tank 101. A nozzle 104 is provided on the side wall of the primary separation pipe 103. A gas-liquid interface 102 communicating with the primary separation pipe 103 is also fixedly connected to the side wall of the connecting body 1.

[0032] The inner wall of the connector 1 is fixedly connected to a secondary separation baffle 4 and a tertiary separation tube 401. The secondary separation baffle 4 is U-shaped, and the tertiary separation tube 401 is located inside the secondary separation baffle 4. Both the secondary separation baffle 4 and the tertiary separation tube 401 are provided with through holes.

[0033] Since both ends of the separator 101 are open, the secondary separation baffle 4 and the tertiary separation pipe 401 are also located inside the separator 101.

[0034] The primary separation pipe 103 is also fixed to the inner wall of the connector 1 and is located inside the separation tank 101.

[0035] The secondary separation baffle 4 and the primary separation pipe 103 are located on both sides of the separation tank 101, respectively.

[0036] The top of the connector 1 is provided with a heat dissipation mechanism that communicates with the separator 101, and a liquid outlet 205 is connected to the heat dissipation mechanism; the side wall of the connector 1 is fixedly connected with an air outlet 402 that communicates with the three-stage separation pipe 401.

[0037] During operation, the coolant, which is in a liquid-gas mixture state, enters the first-stage separation pipe 103 through the gas-liquid interface 102, and then is sprayed onto the inner wall of the separation tank 101 through the nozzle 104. After the liquid-gas mixture comes into contact with the inner wall of the separation tank 101, it generates a collision principle and uses the mass difference between the gas and the liquid to achieve gravity separation. The gas remains above the separation tank 101, while the liquid is located at the bottom of the separation tank 101, thus achieving the first stage of liquid-gas separation. The liquid is stored in the separation tank 101, and then the gas enters through the second-stage separation baffle 4 and enters the third-stage separation pipe 401. Through the through holes on the second-stage separation baffle 4 and the third-stage separation pipe 401, the second-stage liquid-gas separation and the third-stage liquid-gas separation are further achieved. The separated liquid falls to the bottom of the separation tank 101 by its own gravity, and finally the gas is discharged through the gas outlet 402.

[0038] The separated coolant, under the pressure of the air entering along with the air-liquid interface 102, will enter the heat dissipation mechanism. After the temperature is reduced by the heat dissipation mechanism, it will enter the outlet interface 205 and then be discharged for recycling.

[0039] Through the design of the first-stage separation pipe 103, the second-stage separation baffle 4, and the third-stage separation pipe 401, with the second-stage separation baffle 4 and the third-stage separation pipe 401 located on both sides of the separation tank 101 respectively, three-stage liquid-gas separation is achieved, greatly improving the efficiency of liquid-gas separation. Moreover, the entire liquid-gas separation mechanism only has components such as the connecting body 1, the separation tank 101, and the heat dissipation mechanism. Therefore, the structure is simple, allowing for more stable and long-term operation. It is also small in size, occupying less vehicle space and not encroaching on the space of other components. Furthermore, the simple structure results in low weight, which in turn reduces the vehicle's weight and ensures the vehicle's driving range.

[0040] The connector 1 and the separator 101 are connected and fixed together by welding and sealing.

[0041] like Figure 4 The primary separation pipe 103 is located inside the upper part of the separation tank 101; the nozzle 104 is located on the upper surface of the primary separation pipe 103.

[0042] The coolant, which is in a liquid-gas state, is sprayed out through nozzle 104 and sprayed onto the top inner wall of the separator 101. The separated liquid then falls into the bottom of the separator 101.

[0043] By designing the primary separation pipe 103 inside the upper part of the separation tank 101 and spraying the nozzle 104 towards the inner wall of the top of the separation tank 101, the liquid-gas separation efficiency is achieved by taking advantage of the greater distance between the liquid at the top and bottom of the separation tank 101.

[0044] The secondary separation baffle 4 and the tertiary separation pipe 401 are also located inside the upper part of the separation tank 101.

[0045] like Figures 1-3 The technical solution for the heat dissipation mechanism is further refined:

[0046] The heat dissipation mechanism includes multiple heat sinks 2 and connectors 201. The multiple heat sinks 2 are connected through connectors 201, and each of the multiple heat sinks 2 is connected to a heat pipe 203.

[0047] Heatsink 2 is a three-unit design, connected via two connectors 201, such as... Figures 1-3 The three heat sinks are designed in a gate shape.

[0048] The side wall of the connector 1 is connected to an inlet 202, which is flush with the bottom inner wall of the separator 101. The side of the connector 1 away from the inlet 202 is provided with a storage chamber 204.

[0049] The separator 101, the inlet 202, and the storage chamber 204 are interconnected; the outlet 205 is connected to the storage chamber 204.

[0050] like Figure 3The heat dissipation pipe 203 consists of multiple sets of slender square pipes, with a quantity of 4-15 sets, preferably 5 sets. When liquid enters the heat dissipation pipe 203 through the liquid inlet 202, it is quickly dissipated through the heat dissipation fins 2.

[0051] The liquefied coolant, under the action of air pressure, enters the heat dissipation pipe 203 through the inlet 202, and then the heat is transferred to the heat sink 2 for heat dissipation. Finally, it flows into the storage chamber 204 and is discharged through the outlet 205.

[0052] Both the heat sink 2 and the heat pipe 203 are made of metal, preferably aluminum alloy, to meet the pressure requirements of the air compressor.

[0053] like Figure 1 and Figure 3 The liquid-gas separation mechanism disclosed in this embodiment also includes a pressure plate 3; the pressure plate 3 is fixedly connected to the side wall of the connecting body 1, and the pressure plate 3 is fixedly connected to the connecting body 1 by bolts.

[0054] In other words, the sidewall of one of the connecting bodies 1 is hollowed out, and then sealed and connected by the pressure plate 3.

[0055] With the design of the pressure plate 3 and the fact that both ends of the separator 101 are open, the pressure plate 3 can be disassembled after long-term operation to perform maintenance on the inside of the separator 101, thus improving the convenience of maintenance.

[0056] The pressure plate 3 is equipped with a liquid inlet 301, a pressure gauge 302, and a sight glass 303.

[0057] When the coolant is found to be insufficient, it can be added through the filler port 301, which is normally in a closed state.

[0058] Pressure gauge 302 is used to detect the pressure value inside separation tank 101.

[0059] The sight glass 303 is made of transparent steel tube glass or transparent plastic, which makes it easy for maintenance engineers to observe the internal condition of the separator 101.

[0060] like Figure 1 The side wall of the connector 1 is also equipped with a drain valve 304. When it is necessary to completely replace the coolant, the drain valve 304 is opened to drain the coolant in the separator 101 and other pipes.

[0061] The drain valve 304 is located at the bottom of the separator 101 and is flush with the bottom of the inner wall of the separator 101.

[0062] A temperature bypass valve 305 is installed in the liquid inlet 202 on the side wall of the connector 1. When the coolant temperature is low, only half of the coolant directly enters the heat dissipation pipe 203 to avoid coolant failure at low temperature.

[0063] A filter 403 and a pressure maintaining valve are installed on the air outlet 402.

[0064] The gas discharged from the outlet port 402 is filtered by the filter 403 when it passes through the filter 403.

[0065] Pressure maintaining valves are used to maintain air pressure.

[0066] A filter is also installed in the liquid storage chamber 204. A small amount of impurities collect on the filter. The filter is replaced regularly to prevent impurities in the coolant from entering the vehicle air compressor 501.

[0067] Example 2:

[0068] Reference Figures 1-8 Based on Example 1, a vehicle-mounted air compressor cooling device is proposed.

[0069] A vehicle-mounted air compressor cooling device further includes a base 5, which serves as a support. The connecting body 1 and the separator 101 are both fixed on the base 5. A motor 6 is fixedly connected to the base 5, and a fan 601 is fixedly connected to the output end of the motor 6. The fan 601 blows towards the heat dissipation mechanism, specifically, the fan 601 blows towards the heat sink 2.

[0070] The heat dissipation mechanism is located between the fan 601 and the vehicle-mounted air compressor 501.

[0071] Both the gas-liquid interface 102 and the liquid outlet interface 205 are connected to the vehicle-mounted air compressor 501 through pipes. After the coolant dissipates heat from the vehicle-mounted air compressor 501, the coolant, which is in a liquid-gas mixed state, enters the gas-liquid interface 102 through the pipe under the action of air pressure, and finally enters the first-stage separator 103.

[0072] Then, after liquid-gas separation and cooling, the coolant enters the vehicle-mounted air compressor 501 again through the outlet port 205 and pipes for circulation and heat dissipation.

[0073] like Figure 5 , Figure 7 , Figure 8 A guide shroud 602 is also fixedly connected to the base 5. The fan 601 is fixed inside the guide shroud 602. The guide shroud 602 guides the airflow. The airflow generated by the fan 601 passes through the guide shroud 602 and can only pass through the heat sink 2 to carry away the heat.

[0074] At the same time, the air guide cover 602 also serves to support and protect the fan 601.

[0075] The vehicle-mounted air compressor 501 is also installed on the base 5.

[0076] When in operation, the motor 6 is started, which drives the fan 601 to rotate. The airflow carries away the heat from the heat sink 2, further improving the cooling efficiency of the vehicle-mounted air compressor 501.

[0077] The vehicle-mounted air compressor cooling device uses coolant to dissipate heat from the air compressor. The coolant, which is in a liquid-gas mixed state, enters the gas-liquid interface through the pipeline under the action of air pressure, and finally enters the first-stage separator pipe. After liquid-gas separation and cooling, the coolant re-enters the vehicle-mounted air compressor through the liquid outlet and pipeline for circulation and heat dissipation.

[0078] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
