Description

Technical Field

[0001] This utility model relates to the field of cooler technology, and in particular to a composite cooler. Background Technology

[0002] Locomotive parts manufacturing refers to the process of producing various components required for locomotives. These components play a crucial role in the normal operation, safety, and performance of locomotives. A composite cooler is a highly efficient cooling device, typically composed of two or more different types of coolers. It aims to improve cooling efficiency, save space, and adapt to specific operating conditions. The design of a composite cooler can combine different cooling mechanisms, such as evaporative cooling and air cooling, to achieve optimal cooling performance. This composite cooler is described as having a high-efficiency all-aluminum alloy plate-fin cooling structure, with a water radiator at the top and an oil radiator at the bottom, suitable for cooling the main transformer and main converter of high-power electric locomotives. This type of composite cooler has the advantages of a large heat transfer area per unit volume, excellent performance, small shape and size, and compact size.

[0003] In an existing composite cooler, when the entire device is used for a long time, the cooling copper tubes and fins are prone to accumulating dirt and carbon deposits. The difficulty in disassembling these components makes them difficult to clean and maintain, which in turn affects the cooling efficiency and the long-term stable operation of the equipment. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a composite cooler.

[0005] This utility model is achieved by the following technical solution: a composite cooler, including a heat dissipation frame, a heat dissipation fan fixedly connected inside the heat dissipation frame, and a fixed frame threadedly connected inside the heat dissipation frame;

[0006] Fixed sleeve plates are fixedly connected to the left and right ends of the fixed frame. Positioning pins are inserted into the inside of the fixed sleeve plates. A heat dissipation frame is inserted into the inside of the fixed frame. A finned circular frame is inserted into the front of the heat dissipation frame. A positioning plate is fixedly connected to the surface of the finned circular frame. A fixing screw is threaded into the inside of the positioning plate. An inlet pipe is fixedly connected to the rear end of the fixed frame. A sealing plug is inserted into the inside of the inlet pipe. A heat dissipation copper pipe is inserted into the front of the inlet pipe. An outlet pipe is inserted into the rear end of the heat dissipation copper pipe. An installation groove is opened on the front of the heat dissipation frame. Installation fins are inserted into the inside of the installation groove. A sealing baffle is fixedly connected to the front of the heat dissipation frame.

[0007] Through the above technical solution, a cooling fan is installed inside the heat dissipation frame. The cooling fan can accelerate airflow, remove heat, and improve heat dissipation efficiency. A finned circular frame is inserted into the front of the heat dissipation frame. The fins on the finned circular frame increase the heat dissipation area, and together with the cooling fan, it can dissipate heat more effectively.

[0008] As a further improvement to the above solution, the number of positioning plates and fixing screws is set to four, and the four positioning plates and fixing screws are symmetrically distributed on the left and right sides with the finned circular frame as the center.

[0009] As a further improvement to the above solution, the fixing screw extends through the positioning plate into the interior of the fixing frame, and the finned circular frame is located at the rear end of the heat dissipation copper pipe.

[0010] The above technical solution allows the finned circular frame to be precisely positioned and fixed within the fixed frame by four positioning plates and fixing screws, ensuring accurate positioning of the finned circular frame during heat dissipation and improving heat dissipation efficiency.

[0011] As a further improvement to the above solution, the number of the fixing sleeve and positioning pin is set to four, and each pair forms a group. The four fixing sleeves and positioning pins are symmetrically distributed on the left and right sides with the fixing frame as the center.

[0012] As a further improvement to the above solution, the number of mounting slots is set to several, and the several mounting slots are symmetrically distributed on the left and right sides with the fixed frame as the center. Mounting fins are inserted into the interior of the fixed frame.

[0013] As a further improvement to the above solution, the number of sealing baffles is set to two, and the two sealing baffles are symmetrically distributed vertically around the fixed frame.

[0014] As a further improvement to the above solution, the mounting fins are located on the front of the heat dissipation copper pipe, and the heat dissipation copper pipe is inserted into the interior of the fixed frame.

[0015] This invention allows for the removal of several mounting fins from the mounting slots and fixed frame by pulling the positioning pin after prolonged use of the equipment. This enables the removal of the heat dissipation copper pipes from the front of the inlet and outlet pipes. The fixing screw is then rotated to remove the fins from the fixed frame and finned circular frame. The finned circular frame can also be removed from the front of the heat dissipation frame. This facilitates convenient maintenance, repair, and replacement of the finned circular frame, heat dissipation copper pipes, and mounting fins after prolonged use, thus extending the equipment's lifespan.

[0016] This invention incorporates a heat dissipation copper pipe inserted into a fixed frame. The inlet pipe, the heat dissipation copper pipe, and the outlet pipe form a liquid heat dissipation channel, through which the coolant absorbs heat as it flows. Furthermore, the heat dissipation copper pipe, located at the rear end of the finned circular frame and the front of the mounted fins, can conduct heat to the fins. The heat is further dissipated through the fins and the cooling fan. This combination of multiple heat dissipation methods improves the overall heat dissipation capacity. Attached Figure Description

A heat dissipation frame 6 is inserted into the interior of the fixed frame 3. A finned circular frame 7 is inserted into the front of the heat dissipation frame 6. A positioning plate 8 is fixedly connected to the surface of the finned circular frame 7. A fixing screw 9 is threaded into the interior of the positioning plate 8. An inlet pipe 10 is fixedly connected to the rear end of the fixed frame 3. A sealing plug 11 is inserted into the interior of the inlet pipe 10. A heat dissipation copper pipe 12 is inserted into the front of the inlet pipe 10. A discharge pipe 13 is inserted into the rear end of the heat dissipation copper pipe 12. An installation groove 14 is opened on the front of the heat dissipation frame 6. Installation fins 15 are inserted into the interior of the installation groove 14. The front of the heat dissipation frame 6 is fixed... With the sealing baffle 16 connected, after the equipment has been used for a long time, when the positioning pin 5 is pulled out from the inside of the fixed sleeve plate 4, several mounting fins 15 are slid out from the inside of the mounting groove 14 and the fixed frame 3, and the heat dissipation copper pipe 12 is removed from the front of the liquid inlet pipe 10 and the discharge pipe 13. The fixing screw 9 is rotated to remove it from the inside of the fixed frame 3 and the fin round frame 7, and the fin round frame 7 can be removed from the front of the heat dissipation frame 6. When the heat dissipation frame 6 is slid out from the inside of the fixed frame 3, it is convenient for the staff to perform convenient maintenance, repair and replacement of the fin round frame 7, heat dissipation copper pipe 12 and mounting fins 15 after long-term use, thus increasing the service life of the equipment.

[0028] The heat dissipation frame 1 is equipped with a heat dissipation fan 2 inside. The heat dissipation fan 2 can accelerate airflow, remove heat, and improve heat dissipation efficiency. The heat dissipation frame 6 has a finned circular frame 7 inserted on the front. The fins on the finned circular frame 7 increase the heat dissipation area, and together with the heat dissipation fan 2, they can dissipate heat more effectively.

[0029] The number of positioning plates 8 and fixing screws 9 is set to four, and the four positioning plates 8 and fixing screws 9 are symmetrically distributed on the left and right sides with the finned circular frame 7 as the center.

[0030] The fixing screw 9 extends through the positioning plate 8 into the interior of the fixing frame 3, and the finned circular frame 7 is located at the rear end of the heat dissipation copper pipe 12.

[0031] The finned circular frame 7 has four positioning plates 8 and fixing screws 9, which can accurately position and fix the finned circular frame 7 in the fixed frame 3, ensuring that the finned circular frame 7 is accurately positioned during the heat dissipation process and improving the heat dissipation efficiency.

[0036] The implementation principle of a composite cooler in this embodiment is as follows: After the entire device has been used for a long time, when the positioning pin 5 is pulled out from the inside of the fixed sleeve plate 4, several mounting fins 15 are slid out from the inside of the mounting groove 14 and the fixed frame 3, and the heat dissipation copper pipe 12 is removed from the front of the liquid inlet pipe 10 and the discharge pipe 13. The fixing screw 9 is rotated to remove it from the inside of the fixed frame 3 and the fin round frame 7, and the fin round frame 7 can be removed from the front of the heat dissipation frame 6. When the heat dissipation frame 6 is slid out from the inside of the fixed frame 3, it is convenient for the staff to clean the device after long-term use.

By setting the heat dissipation copper pipe 12 to be inserted inside the fixed frame 3, the liquid inlet pipe 10, heat dissipation copper pipe 12, and outlet pipe 13 form a liquid heat dissipation channel. When the coolant flows in it, it can absorb heat. Furthermore, the heat dissipation copper pipe 12 is located at the rear end of the finned circular frame 7 and the front of the mounting fins 15, which can conduct heat to the fins. The heat is further dissipated through the fins and the cooling fan 2. This structure, which combines multiple heat dissipation methods, improves the overall heat dissipation capacity.
