[0042] In some embodiments, the side of the first main body 21 near the conversion member 3, the side of the second main body 22 near the conversion member 3, and the side of the third main body 23 near the conversion member 3 are aligned.

[0045] In some embodiments, the body part 301 has a first chamber 313 and a second chamber 314 for communicating with the pipe part 4, the first chamber 313 communicates with the first hole 210, and the second chamber 314 communicates with the second hole 211. The body part 301 is located on the same side of the first current collecting part 2 as the main body part 1.

[0046] In some embodiments, the conversion part 3 includes a first part and a second part, which are independent of each other. The first part has a first chamber 313, which communicates with the first hole 210, and seals the first current collecting opening 218. The second part has a second chamber 314, which communicates with the second hole 211, and seals the second current collecting opening 219.

[0047] In some embodiments, as shown in Figures 5 to 7 , the conversion part 3 includes a first adapter 31 and a second adapter 32, which are fitted together and fitted on the extension part 202. Optionally, the first adapter 31 and the second adapter 32 are brazed together.

[0048] As shown in Figure 8 and Figure 9 , the first adapter 31 is a block-shaped body, which includes a first adapter part 311 and a second adapter part 312, the second adapter part 312 extends from the first adapter part 311 towards the first current collecting chamber opening 218. The first adapter part 311 is located on the same side of the first main body part 21 as the main body part 1. The first adapter part 311 and the second adapter part 312 are an integral part, which has the advantages of simple structure, reliable connection, and convenient processing.

[0049] Specifically, the first adapter 31 is an L-shaped block, as shown in Figure 5 , the first adapter part 311 is located at the position of the L-shaped bottom side, and the second adapter part 312 is located at the position of the L-shaped side. The first adapter part 311 is located on the lower side of the first main body part 21, and the second adapter part 312 is located on the left side of the first main body part 21.

[0050] The first adapter 311 has a first chamber 313 and a second chamber 314, which are spaced apart. The first adapter 311 is connected with the extension 202. Specifically, the first adapter 311 has a fifth hole 315, a sixth hole 316, a seventh hole 318 and an eighth hole 319. The fifth hole 315 and the seventh hole 318 are respectively located at two ends of the first chamber 313, and the fifth hole 315 and the seventh hole 318 respectively communicate with the first chamber 313. The fifth hole 315 communicates with the first hole 210, and the seventh hole 318 communicates with the inner cavity of the first pipe 41. The sixth hole 316 and the eighth hole 319 are respectively located at two ends of the second chamber 314, and the sixth hole 316 and the eighth hole 319 respectively communicate with the second chamber 314. The sixth hole 316 communicates with the second hole 211, and the eighth hole 319 communicates with the inner cavity of the second pipe 42. Optionally, the fifth hole 315 and / or the sixth hole 316 are waist-shaped holes. This arrangement can increase the contact area of the wall surface surrounding the fifth hole 315 and / or the wall surface surrounding the sixth hole 316 with the fluid, thereby reducing the flow resistance of the fluid.

[0051] Specifically, in some embodiments, the first chamber 313 and the second chamber 314 are both substantially L-shaped chambers. For example, when the heat exchanger is in operation, the fluid flowing out of the pipe component 4 flows into the heat exchanger from the first chamber 313 and flows out of the heat exchanger from the second chamber 314. The fluid first flows to the right for a distance and then flows upward for a distance in the first chamber 313. After flowing out of the first chamber 313, the fluid continues to flow upward, sequentially passes through the third hole 320 and the first hole 210, and then flows into the first collecting chamber 214. The fluid flows into the heat exchange pipe 11 through the first collecting chamber 214, and then flows along the heat exchange pipe 11 to the second collecting chamber 215. The fluid flowing out of the second collecting chamber 215 flows downward, sequentially flows through the second hole 211 and the fourth hole 321, and then flows into the second chamber 314. In the second chamber 314, the fluid first flows downward for a distance, then flows to the left for a distance, and then flows out of the pipe component 4. The fluid exchanges heat with another fluid outside the heat exchange pipe 11 when flowing in the heat exchange pipe 11. In this way, when the fluid flows into the first collecting chamber 214, the flow direction of the fluid is perpendicular to the flow direction of the fluid in the first collecting chamber 214 along the extension direction of the first collecting chamber 214, so that the fluid is uniformly distributed in the first collecting chamber 214, thereby uniformly distributing the fluid to the heat exchange pipe 11 and improving the heat exchange effect of the heat exchanger.

[0052] Figure 10A second adapter 312 is shown in some embodiments. The second adapter 32 includes a connecting portion 322 and a bending portion 323.

The third bent portion 3233 has a plurality of first openings 3234, which are arranged along the depth direction of the first groove 3230. Optionally, the third bent portion 3233 is serrated. The first openings 3234 can enhance the connection strength between the third bent portion 3233 and the second transition portion 312, thereby increasing the connection strength between the first transition member 31 and the second transition portion 32. In some other embodiments, a plurality of through holes can be provided on the third bent portion 3233 to replace the above-mentioned first openings 3234. Optionally, the first groove 3230 is a U-shaped groove.

Specifically, the second groove 326 fits onto one side of the first plate 216 located in the width direction of the protrusion 202. Optionally, the second groove 326 is a U-shaped groove.

[0061] The fifth bend 3242 has a second opening 3240 facing the second hook portion 325. In some other embodiments, a plurality of through holes may be provided in the fifth bend 3242 instead of the second opening 3240.

[0062] In some embodiments, the second hook portion 325 includes a sixth bend portion 3251 and a seventh bend portion 3252. One side of the sixth bend portion 3251 is connected to the first receiving plate 328, and the other side of the sixth bend portion 3251 is connected to the seventh bend portion 3252.
