Description

Technical Field

[0001] This utility model relates to a radiator module for auxiliary air supply, specifically a radiator module used inside the auxiliary air supply equipment of rail vehicles to cool down the high-temperature compressed air discharged from the compressor. Background Technology

[0002] Auxiliary air supply equipment for rail vehicles is a common device that provides auxiliary compressed air to rail vehicles. When the total air pressure of the rail vehicle is insufficient, the air compressor inside the auxiliary air supply equipment needs to operate to provide compressed air to the pantograph raising device, so that the pantograph of the vehicle can be raised to provide power to the entire train.

[0003] Auxiliary air supply equipment is typically installed under the vehicle. This necessitates that its enclosure have excellent sealing properties to ensure that internal components are not damaged by rainwater or other corrosive agents.

[0004] The compressor inside the auxiliary air supply equipment generates high-temperature compressed air (reaching over 150°C) during operation. Therefore, a radiator is necessary to lower the temperature of the compressed air and prevent damage to downstream pipelines or equipment from the high-temperature gas. Existing auxiliary air supply equipment mostly uses aluminum finned radiators. These radiators require natural wind or an auxiliary fan to maximize their heat dissipation function. Due to the inability to install a cooling fan inside the auxiliary air supply equipment and the lack of a sealed enclosure, the heat dissipation effect of existing aluminum finned radiators is relatively poor.

[0005] Meanwhile, these radiators are mostly welded from aluminum plates and profiles, which poses a risk of leakage and internal blockage later on. This makes them inconvenient for later use and maintenance. Furthermore, condensation will accumulate inside during installation and use, which is difficult to drain and affects the operation of auxiliary air supply equipment. Therefore, we have designed a radiator module for auxiliary air supply. Utility Model Content

[0006] To address the following issues in existing technologies: 1. Aluminum finned radiators have low heat dissipation efficiency in enclosed environments without natural wind or fan assistance; 2. Aluminum finned radiators are assembled as a single unit using welding, which can lead to weld cracking and compressed air leakage due to vibration during use; 3. To improve heat dissipation efficiency, aluminum finned radiators have internal fins in their channels, which can cause channel blockage during use. The only solution is to replace the radiator to ensure normal operation, which is time-consuming and labor-intensive; 4. During operation, when the temperature of the compressed air inside the radiator decreases, the water vapor in the air condenses into liquid water and accumulates inside the radiator. Later maintenance requires disassembling the entire radiator and draining the accumulated water; 5. In the layout of auxiliary air supply equipment piping, safety valves and other components can only be connected to the radiator's inlet and outlet, occupying a large space and making design layout inconvenient. Therefore, this utility model provides a radiator module for auxiliary air supply.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: The heat sink has an intake and exhaust transition duct on one side and two drain holes on the other side. The drain holes are connected to the intake and exhaust transition ducts. Drain hole plugs are installed at the drain holes.

[0008] One side of the heat sink has a curved air passage along which compressed air can flow. The other side has a threaded interface and an exhaust interface. The threaded interface, exhaust interface and curved air passage are not directly connected, but are connected through an intake transition air passage and an exhaust transition air passage under the heat sink.

[0009] The air inlet connector, air outlet connector, safety valve, and test connector are all installed on the threaded interface and air outlet of the heat sink via transition connectors.

[0010] Both the upper and lower parts of the heat sink are made of aluminum alloy sheet.

[0011] The sides of the heat sink with air ducts are attached together, and a sealing ring is placed between the heat sink fins. The heat sink fins are connected as a whole by screws to form a heat sink. The above-mentioned connectors and components are installed on the heat sink to form a heat sink module.

[0012] The beneficial effects of this utility model are as follows: 1) The radiator module of this utility model is made of aluminum plate. During installation, its surface is in close contact with the inner wall of the enclosure. Through heat transfer with the enclosure, the heat dissipation area is increased, and the heat dissipation efficiency is improved. Alternatively, heat dissipation holes can be set in the contact area between the radiator module and the enclosure, relying on the airflow outside the enclosure to improve heat dissipation efficiency. At the same time, since the radiator completely covers the heat dissipation holes, the sealing performance of the enclosure is guaranteed.

[0013] 2) The radiator of this utility model is made of aluminum plate, and the heat sink fins are sealed with sealing rings, so there is no risk of cracking and leakage during use. During later maintenance, the sealing performance can be ensured by replacing the sealing rings.

[0014] 3) If the radiator module of this utility model becomes clogged during use, the radiator can be disassembled, the internal channels can be cleaned, and the blockage point can be removed before it can be put into use again, making maintenance convenient.

[0015] 4) The radiator module of this utility model is provided with a drain hole at the bottom. During later inspection and maintenance, the drain hole plug can be removed to drain the accumulated water.

[0016] 5) The heat sink module of this utility model can be designed with an interface added at any position to install the required components, which facilitates the design layout. Attached Figure Description

[0019] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the following examples provide a more detailed description of this utility model. It should be noted that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit its scope.

[0020] See appendix Figures 1-4 As shown, an auxiliary air supply radiator module of this utility model includes an upper heat sink 101, a lower heat sink 201, a sealing ring 9, a transition joint 3, an air inlet joint 7, an air outlet joint 4, a safety valve 6, a test joint 5, and a drain hole plug 8.

[0021] An air intake transition channel 204 and an air exhaust transition channel 203 are provided on one side of the heat sink 201, and two drain holes 202 are provided on the other side. The drain holes 202 are connected to the air intake transition channel 204 and the air exhaust transition channel 203. A drain hole plug 8 is installed at the drain hole 203.

[0022] A curved air passage 102 is provided on one side of the heat sink 101, along which compressed air can flow. A threaded interface 103 and an air outlet 104 are provided on the other side. The threaded interface 103, the air outlet 104 and the curved air passage 102 are not directly connected, but are connected through the air inlet transition passage 204 and the air outlet transition passage 203 under the heat sink 201.

[0023] The air inlet connector 7, the air outlet connector 4, the safety valve 6, and the test connector 5 are all installed on the heat sink 101 at the threaded interface 103 and the air outlet 104 via the transition connector 3.

[0024] Both the upper 101 and lower 201 of the heat sink are made of aluminum alloy sheet.

[0025] The sides of the heat sink 101 and the bottom heat sink 201, which have air passages, are attached to each other, and a sealing ring 9 is provided between the heat sinks. The heat sinks are connected as a whole by screws to form a heat sink. The above-mentioned connectors and components are installed on the heat sink to form a heat sink module.

[0026] In use, high-temperature compressed air enters the radiator module through the inlet connector 7. The compressed air flows through the transition air passage 202 under the heat sink 201 into the curved air passage 102 on the heat sink 101. The high-temperature compressed air flows within the curved air passage 102, and during this flow, the high temperature is transferred to the heat sink 101 and under the heat sink 201, causing the compressed air temperature to decrease. Finally, it flows out of the radiator module through the outlet connector 4. The inlet transition air passage 204 under the heat sink 201 connects to the inlet connector 7, the safety valve 6, and the test connector 5, allowing the pressure of the incoming compressed air to be directly detected at both the safety valve 6 and the test connector 5. When the pressure exceeds the set value of the safety valve 6, the safety valve releases pressure, protecting the radiator module and auxiliary air supply equipment. The test connector 5, located here, can be connected to an external pressure gauge to monitor the incoming compressed air pressure in real time and can also calibrate the opening pressure of the safety valve 6. The heat sink 201 is located below the heat sink module. When condensate is generated in the curved air passage 102, the condensate can flow into the intake transition air passage 204 and the exhaust transition air passage 203. During later equipment maintenance, the drain hole plug 8 can be removed to drain the condensate and ensure the air passage is clean.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
