At present, a header of a heat exchanger can supply a refrigerant to flow, in order to change the flow direction of the refrigerant, a partition plate 120 needs to be arranged in the header, the partition plate 120 blocks a pipe cavity of the header, and a flow path is blocked when the refrigerant flows to the partition plate 120, so that the refrigerant cannot directly flow in the header through the partition plate 120. When the partition plate 120 is assembled in the existing header, a clamping groove is formed in the header, the partition plate 120 is inserted into the clamping groove, and the partition plate 120 is hermetically connected with the inner pipe wall of the header, so that the partition plate 120 plays a role in blocking a pipe cavity of the header. When the partition plate 120 is connected with the inner pipe wall of the header in a sealing manner, if leakage occurs at the connection position of the partition plate 120 and the header, the blocking function of the partition plate 120 is affected, and part of fluid cannot be blocked by the partition plate 120 and directly passes through the partition plate 120 from a gap to continuously flow in the header, so that the heat exchange performance of the heat exchanger is affected. The connection position of the partition plate 120 and the inner pipe wall of the header pipe is located inside the header pipe, and the inner leakage is not convenient to detect when the leakage occurs, and the misjudgment is easy to occur when the leakage occurs, so that the heat exchange performance of the heat exchanger is influenced.
Referring to fig. 1 to 4, in the present embodiment, a heat collecting pipe of a heat exchanger is provided, where a position blocked by the heat collecting pipe is not easy to leak, and even if a leak occurs, the leak is also an external leak, which is convenient for detection, improves accuracy of leak detection of the heat collecting pipe, reduces a misjudgment rate, and ensures heat exchange performance of the heat exchanger.
In this embodiment, the heat exchanger manifold includes:
the tube unit 100, the tube unit 100 includes an integrally formed tube body 110 and a partition 120, the tube body 110 is provided with a flat tube slot 111 for being in plug-in fit with the flat tube 200, and the partition 120 blocks a tube cavity of the tube body 110.
The heat exchanger collecting pipe that this embodiment provided, including at least one tube unit 100, tube unit 100 includes integrated into one piece's body 110 and baffle 120, because body 110 and baffle 120 integrated into one piece, the lumen of body 110 can be blocked to baffle 120, and does not have the concatenation gap between the two, and sealing performance is good, is difficult for appearing leaking the phenomenon, and the qualification rate of collecting pipe is high, and the safety in utilization is high.
Meanwhile, when the length of a single pipe unit 100 cannot meet the use requirement, namely when a plurality of pipe units 100 are required to be spliced to increase the length of the collecting pipe, the end parts of the pipe bodies 110 of the adjacent pipe units 100 are hermetically connected, and because gaps exist around the pipe bodies 110, the spliced pipe bodies 110 are externally leaked even if leakage occurs at the spliced seams, so that observation and detection are facilitated, the probability of missed detection and misjudgment is greatly reduced, the quality of the collecting pipe is higher, the performance is better, and the use performance of the heat exchanger is improved.
