Header pipe baffle plate capable of preventing inner leakage

Abstract

The invention provides a header pipe baffle plate capable of preventing inner leakage, which is used in a heat exchanger. The header pipe baffle plate comprises a single-layer baffle plate or two partition plates, wherein, a groove is arranged on a circumferential side of the single-layer baffle plate, and the section of the groove is in a triangular, rectangular, square or semicircular shape; a single face of one partition plate is equipped with a plurality of contour bosses, the bosses are clamped between the two partition plates so that the two partition plates are spaced from each other, and the bosses are circular, strip-shaped or rectangular platforms; or a single face of one partition plate or single faces of two partition plates are equipped with conical platforms, and the conical platforms are clamped between the two partition plates so that the two partition plates are spaced from each other. In the header pipe baffle plate, the groove is arranged on the circumferential side of the single-layer baffle plate or a clearance is arranged between the two partition plates; and when a gap exists between the baffle plate and a header pipe, the interior of a heat exchanger is communicated with atmosphere through the gap via the groove or the clearance, which can be inspected through a helium leak detection link, thus preventing delivery of unqualified heat exchangers.

Description

technical field [0001] The invention relates to a component used in a heat exchanger, in particular to an anti-inner leakage collecting tube partition. Background technique [0002] The structure of the microchannel heat exchanger is as figure 1 As shown, it includes a header 1 and heat exchange tubes 2 , and a plurality of heat exchange tubes 2 are respectively connected between the two headers 1 . In the collecting pipe, sometimes it is necessary to install a partition 3, which is inserted vertically into the collecting pipe, so that the circumferential side of the partition is closely attached to the inner wall of the collecting pipe, so that the collecting pipe is separated into a Several sections isolated from each other divide the entire heat exchanger into multiple processes. The refrigerant flows in from the inlet pipe 4, and flows out through the outlet pipe 5 after passing through the N process heat exchanger. If there is a gap between the circumferential side o...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the existing defect that it is impossible to detect whether there is a gap between the collecting tube and the partition through visual inspection or instruments, and to invent a method that can make the gap between the circumferential side of the partition and the tube wall of the collecting tube Anti-inner leakage header partition communicated with the outside world
