Description

Technical Field

[0001] This utility model mainly relates to the field of heat exchange technology, specifically to a heat transfer oil radiator for methanol reforming hydrogen fuel cells. Background Technology

[0002] The working principle of methanol reforming hydrogen fuel cells mainly involves two processes: methanol conversion and hydrogen utilization. During the preheating stage, the heat transfer oil is heated by the hot flue gas and the heating rod, and then circulated by an electric water pump to preheat the high-temperature fuel cell stack. After the high-temperature fuel cell stack enters the power generation state, the heat transfer oil, together with the heat transfer oil radiator and the cooling fan, can dissipate the heat generated in the high-temperature fuel cell stack to the outside to ensure the temperature balance of the high-temperature fuel cell stack.

[0003] During the reaction process, heat transfer oil is circulated into a heat transfer oil radiator, which releases the heat from the continuously circulating oil into the atmosphere. However, traditional heat transfer oil radiators are generally one-piece fixed structures. During installation, multiple heat exchange tubes are typically welded directly between two tube sheets, and U-shaped connecting pipes are welded to the outside of the tube sheets to connect all the heat exchange tubes sequentially. This design makes the overall structure non-adjustable, preventing adjustments to the heat exchange tube arrangement based on the installation environment, and also making it impossible to increase or decrease the number of heat exchange tubes based on heat transfer efficiency. Furthermore, the welding and fixing method for the heat exchange tubes and U-shaped connecting pipes is cumbersome and inconvenient to install. Therefore, it is necessary to propose an improvement to solve the above-mentioned technical problems.

[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model:

[0006] This utility model provides a heat-conducting oil radiator to solve the technical problems existing in the background art.

[0007] 2. Technical Solution:

[0008] To achieve the above objectives, the technical solution provided by this utility model is as follows: a heat transfer oil radiator, comprising several radiator units, which can be assembled horizontally or vertically; each radiator unit includes two heat exchange tubes arranged side by side and tube sheets disposed on both sides of the heat exchange tubes, wherein a U-shaped connecting pipe is detachably installed on one side of the tube sheet, and the two heat exchange tubes of the radiator unit are sealed and connected through the U-shaped connecting pipe on one side; a U-shaped connecting pipe is also detachably installed between the tube sheets on the other side of two adjacent radiator units, and the heat exchange tubes of two adjacent radiator units are sealed and connected through the U-shaped connecting pipe on the other side; the heat exchange tubes of the several radiator units can be connected sequentially.

[0009] Furthermore, two through holes are correspondingly provided on the tube sheet, and mounting grooves are correspondingly provided on both sides of the through holes. An annular sealing ring is correspondingly installed at the bottom of the mounting groove, and a limit block that can elastically slide and extend is correspondingly provided around the opening of the mounting groove. Both ends of the heat exchange tube are correspondingly provided with annular end plates I extending outward. The annular end plates I at both ends of the heat exchange tube can be correspondingly pressed and installed in the mounting groove on the inner side of the tube sheet, and the limit block is used to achieve limiting and fixing. Both ends of the U-shaped connecting tube are correspondingly provided with annular end plates II extending outward. The annular end plates II at both ends of the U-shaped connecting tube can be correspondingly pressed and installed in the mounting groove on the outer side of the tube sheet, and the limit block is used to achieve limiting and fixing.

[0010] Furthermore, the groove in the mounting slot has multiple circumferentially evenly distributed sliding grooves around its opening. A limiting block is slidably installed in the sliding groove. One end of the limiting block has an inwardly inclined slope. The end of the limiting block that does not extend outward is connected to the bottom of the sliding groove by a spring.

[0011] Furthermore, slots and inserts are respectively provided on the left and right side walls of the tube sheet, and the shape and size of the inserts are adapted to the slots.

[0012] Furthermore, the heat exchange tube is provided with multiple heat dissipation rings at equal intervals on its outer side.

[0013] 3. Beneficial effects:

[0014] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0015] This utility model features a reasonable design. By employing a modular assembly design, multiple radiator units can be horizontally assembled sequentially into a single tube arrangement, or vertically stacked into multiple tube arrangements. This allows for adaptive adjustment of the radiator unit arrangement based on the installation environment, thereby adjusting the overall structure. Furthermore, the design optimizes the structure of the tube sheet, heat exchange tubes, and U-shaped connecting tubes. The combination of limiting blocks and springs enables the heat exchange tubes and U-shaped connecting tubes to be tightly engaged for quick installation and disassembly. The operation is very convenient, and the number of heat exchange tube passes can be quickly and effectively increased or decreased during installation. If a heat exchange tube becomes blocked, corroded, or damaged, it can be directly replaced without replacing the entire radiator, effectively saving costs and avoiding resource waste. Its overall design is ingenious, flexible, convenient, and highly practical.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0029] See attached document Figure 1-6 This embodiment of a heat-conducting oil radiator includes several radiator units 1, which can be horizontally assembled together, such as... Figure 1 As shown, this forms a series of tubular heat-conducting oil radiators; alternatively, several individual radiator units 1 can be vertically stacked and assembled together, such as... Figure 2As shown, a multi-row tube-type heat transfer oil radiator is formed, which can effectively and adaptively adjust the installation arrangement of the radiator unit 1 according to the installation environment and other conditions, thereby adjusting its overall structure. It is worth noting that if several radiator units 1 are vertically stacked and assembled together to form a multi-row tube-type heat transfer oil radiator, the number of radiator units 1 required is generally an even number.

[0030] The radiator unit 1 includes two heat exchange tubes 11 arranged side by side and tube sheets 12 disposed on both sides of the heat exchange tubes 11. A U-shaped connecting pipe 2 is detachably installed on one side of the tube sheet 12, and the two heat exchange tubes 11 of the radiator unit 1 are sealed and connected through the U-shaped connecting pipe 2 on one side. A U-shaped connecting pipe 2 is also detachably installed between the tube sheets 12 on the other side of two adjacent radiator units 1, and the heat exchange tubes 11 of two adjacent radiator units 1 are sealed and connected through the U-shaped connecting pipe 2 on the other side. The heat exchange tubes 11 of several radiator units 1 can be connected sequentially.

[0031] Two through holes 123 are correspondingly provided on the tube sheet 12. Mounting grooves 124 are provided on both sides of each through hole 123. A rubber annular sealing ring 13 is installed at the bottom of each mounting groove 124. A limit block 14 that can elastically slide and extend is provided around the opening of each mounting groove 124. Annular end plates I 111 extend outwards from both ends of the heat exchange tube 11. The annular end plates I 111 at both ends of the heat exchange tube 11 can be pressed and installed into the mounting grooves 124 on the inner side of the tube sheet 12, and are fixed by the limit blocks 14. Annular end plates II 21 extend outwards from both ends of the U-shaped connecting tube 2. The annular end plates II 21 at both ends of the U-shaped connecting tube 2 can be pressed and installed into the mounting grooves 124 on the outer side of the tube sheet 12, and are fixed by the limit blocks 14.

[0032] Specifically, multiple circumferentially evenly distributed sliding grooves 125 are provided around the opening of the mounting groove 124. In this embodiment, three sliding grooves 125 are evenly provided around the opening of the mounting groove 124. A limiting block 14 is slidably installed in the sliding groove 125. One end of the limiting block 14 is provided with an inwardly inclined surface. The end of the limiting block 14 that does not extend outward is connected to the bottom of the sliding groove 125 by a spring 15. The spring 15 enables the elastic sliding extension and retraction of the limiting block 14. During installation, the annular end of the heat exchange tube 11 or the U-shaped connecting tube 2 can be directly inserted into the mounting groove 124. Since the end of the limiting block 14 has an inwardly inclined slope, during the insertion of the annular end, the annular end will abut against the inclined surface of the limiting block 14, causing the limiting block 14 to automatically retract into the sliding groove 125 until the annular end is fully inserted into the mounting groove 124 and pressed tightly. The annular sealing ring 13 is used to achieve a seal to prevent leakage. At this time, the limiting block 14 will automatically extend and reset under the action of the spring 15, abutting against one side of the annular end, thereby achieving its fixed position after installation. This embodiment optimizes the structure of the tube sheet 12, heat exchange tube 11, and U-shaped connecting tube 2. By utilizing the cooperation of the limiting block 14 and the spring 15, the heat exchange tube 11 and U-shaped connecting tube 2 can be quickly installed and disassembled by tightly engaging each other. The operation is very convenient, and the number of heat exchange tubes can be quickly and effectively increased or decreased during installation. If the heat exchange tube 11 is blocked, corroded, or damaged, it can be directly replaced without replacing the entire radiator, effectively saving costs and avoiding resource waste.

[0033] The left and right side walls of the tube sheet 12 are respectively provided with slots 121 and inserts 122, and the shape and size of the inserts 122 are adapted to the slots 121. During installation, the inserts 122 of one tube sheet 12 can be inserted into the slots 121 of the adjacent tube sheet 12 to achieve assembly connection.

[0034] Multiple heat dissipation rings are evenly spaced on the outer side of the heat exchange tube 11 for heat conduction. Both the initially connected and the last connected side of the heat exchange tube 11 can be connected to the oil pipe via a pipe connector 3. The pipe connector 3 can be L-shaped, with one end of the connector extending outwards with an annular end plate. During installation, the annular end plate of the pipe connector 3 is inserted into the mounting groove 124 and pressed tightly, using a limiting block 14 for positioning and fixing. The other end of the pipe connector 3 is then connected to the oil pipe, allowing the heat transfer oil to flow into the heat transfer oil radiator for heat dissipation. It is worth noting that during installation, the distance between two heat exchange tubes 11 on the radiator unit 1 can be the same as the distance between two adjacent heat exchange tubes 11 on two adjacent radiator units 1, so that U-shaped connecting pipes 2 of the same size can be used, making installation more convenient. The two ends of the heat exchange tube 11 can also be directly welded to the tube sheets 12 on both sides. If the heat exchange tube 11 is blocked, corroded or damaged, the heat exchange unit 1 can be replaced directly, and there is no need to replace the entire heat exchange unit.

[0035] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
