In existing heat exchangers, the cooling or heating fluid flows in from one end and out from the other. By the time the fluid reaches the end, the temperature has significantly changed, resulting in low heat transfer efficiency. Furthermore, the heat exchange tubes are arranged in a straight line, resulting in low heat transfer efficiency. Utility Model Content

The heat exchange component includes multiple heat exchange tubes, which are installed on the frame. Each heat exchange tube includes a liquid inlet joint, a tube body and a liquid outlet joint. The tube body is connected to the liquid inlet joint and the liquid outlet joint. The liquid inlet joint is connected to the liquid inlet pipe, and the liquid outlet joint is connected to the liquid outlet pipe. The multiple heat exchange tubes are arranged along the extension direction of the liquid inlet pipe and are located in a straight line.

[0006] Furthermore, each of the heat exchange tubes has a plurality of tube bodies, and each of the heat exchange tubes further includes a connecting tube, through which the plurality of tube bodies are connected.

[0007] Furthermore, the plurality of tubes are not located on the same straight line.

[0010] Furthermore, the frame includes a top plate, the top plate includes a plate body and side plates fixed to both sides of the plate body, the connecting pipe is installed on the plate body, and the height of the connecting pipe is lower than the height of the side plates.

[0011] Furthermore, the connecting pipe is U-shaped.

[0012] Furthermore, the liquid inlet joints of the plurality of heat exchange tubes are located in a straight line.

[0014] Furthermore, the frame is rectangular, the tube bodies of the plurality of heat exchange tubes are located in the frame, and the tube bodies of the plurality of heat exchange tubes are arranged in multiple rows along the length direction in the frame.

[0015] Compared with the existing technology, the coil heat exchanger of the present invention includes a frame, a liquid inlet pipe, a liquid outlet pipe and multiple heat exchange tubes. The multiple heat exchange tubes are installed on the frame. Each heat exchange tube includes a liquid inlet joint, a tube body and a liquid outlet joint. The tube body is connected to the liquid inlet joint and the liquid outlet joint. The liquid inlet joint is connected to the liquid inlet pipe, and the liquid outlet joint is connected to the liquid outlet pipe.

[0028] See also Figure 1 The coil heat exchanger includes a frame 10, a heat exchange assembly 20, a liquid inlet pipe 30, and a liquid outlet pipe 40. The heat exchange assembly 20 is mounted on the frame 10 and arranged along the length direction of the frame 10.

[0029] Please continue reading Figure 2The frame 10 is rectangular in shape as a whole, and a heat exchange assembly 20 is installed inside the frame 10. Specifically, the frame 10 includes two side panels 11 and two top panels 12, and the two top panels 12 are fixedly connected to the side panels 11. The side panels 11 are parallel to each other, and the two top panels 12 are also parallel to each other. One top panel 12 is located at the top of the frame 10, and the other top panel 12 is located at the bottom of the frame 10. The top panels 12 are perpendicular to the side panels 11. Each top panel 12 includes a plate body 120 and two side panels 121. The two side panels 121 are fixed to both sides of the plate body 120. The two side panels 121 are parallel to each other, and the side panels 121 are perpendicular to the plate body 120. Each plate body 120 is provided with a mounting hole 1201, and the mounting hole 1201 is used to install the connecting pipe 212. The height of the side panel 121 is greater than the height of the connecting pipe 212, so that the side panel 121 can protect the connecting pipe 212. The side panel 121 at the bottom is also used to install the connecting pipe 212.

[0030] Please continue reading Figure 3 、 Figure 4 as well as Figure 5 Multiple heat exchange tubes 21 are arranged in a straight line along the length of the frame 10. Each heat exchange tube 21 includes a liquid inlet connector 210, multiple tube bodies 211, multiple connecting tubes 212, and a liquid outlet connector 213. The liquid inlet connector 210 is used to connect the tube body 211 to the liquid inlet pipe 30. The connecting tube 212 is used to connect two tube bodies 211. The liquid outlet connector 213 is used to connect the tube body 211 to the liquid outlet connector 213.

[0031] Specifically, the liquid inlet connector 210 is S-shaped, the tube body 211 is linear, the connecting tube 212 is U-shaped, and the liquid outlet connector 213 is S-shaped. The liquid inlet connector 210 is connected to the top of the tube body 211, and the connecting tube 212 connects the bottom or top of the two tube bodies 211. The liquid inlet connector 210, the connecting tube 212 at the top, and the liquid outlet connector 213 are fixed to the mounting hole 1201 of the top roof panel 12, and the connecting tube 212 at the bottom is fixed to the mounting hole 1201 of the bottom roof panel 12. Multiple liquid inlet connectors 210 are located in a straight line, multiple liquid outlet connectors 213 are located in a straight line, and multiple connecting tubes 212 are located in a straight line. The straight line on which the liquid inlet connectors 210 and the straight line on which the liquid outlet connectors 213 are located are the straight lines on which the ends of the connecting tubes 212 are located.

[0032] The tube bodies 211 are arranged along the height direction. Each heat exchange tube 21 includes multiple tube bodies 211, which are staggered and located at different positions. The tube bodies 211 of the multiple heat exchange tubes 21 are arranged in multiple rows, and the multiple rows of tube bodies 211 are staggered to enhance heat exchange efficiency. Specifically, in this embodiment, the tube bodies 211 of the multiple heat exchange tubes 21 are arranged in two rows. The two rows of tube bodies 211 are parallel to each other and staggered.

[0033] The end of the liquid inlet pipe 30 is L-shaped and has a sealed structure. The liquid inlet joints 210 of the plurality of heat exchange tubes 21 are connected to the liquid inlet pipe 30 and arranged along the liquid inlet direction.

[0034] The end of the liquid outlet pipe 40 is L-shaped. The liquid outlet pipe 40 and the liquid inlet pipe 30 are symmetrically arranged, that is, the heat exchange tube 21 flowing into the liquid outlet pipe 40 from the head portion flows out from the end portion of the liquid outlet pipe 40 .

[0035] Please continue reading Figure 6 as well as Figure 7 When assembling the coil heat exchanger, the liquid inlet joint of the heat exchange tube 21 is connected to the liquid inlet pipe 30, and the liquid outlet joint 213 of the heat exchange tube 21 is connected to the liquid outlet pipe 40. Multiple heat exchange tubes 21 are arranged along the extension direction of the liquid inlet pipe 30 until the end of the liquid inlet pipe 30. At this time, multiple connecting pipes 212 are located in a straight line, and the tube bodies 211 of the multiple heat exchange tubes 21 form multiple rows, and the multiple rows of tube bodies 211 are staggered to enhance the heat exchange efficiency. The height of the side plate 121 is greater than the height of the connecting pipe 212, so that the side plate 121 can protect the connecting pipe 212. The liquid inlet joints 210 of multiple heat exchange tubes 21 can enter the exchange liquid at the same time, shortening the travel of the exchange liquid, avoiding excessive temperature changes of the exchange liquid in the latter part of the travel, and reducing the heat exchange efficiency, thereby improving the heat exchange efficiency of the coil heat exchanger.
