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
The present invention is the parts that use on a kind of heat exchanger, particularly a kind of anti-interior header dividing plate that leaks.
Background technology
The structure of micro-channel heat exchanger as shown in Figure 1, it comprises header 1 and heat exchanger tube 2, a plurality of heat exchanger tubes 2 are connected across respectively between two headers 1.In header, sometimes need to install dividing plate 3, dividing plate 3 is vertically to be inserted in the header, makes the circumference side of dividing plate and the inwall of header connect airtight applying, so just header is divided into by the waist isolated each other plurality of sections, makes whole heat exchanger be divided into a plurality of flow processs.Cold-producing medium flows into from inlet tube 4, through being flowed out by outlet 5 behind the N flow process heat exchanger.If leave the space between the circumference side of dividing plate and the header tube wall, the phenomenon of " gas blowby " between flow process N and the flow process N+1 will take place.Gas blowby can cause the part cold-producing medium heat exchanger tube of not flowing through, and has reduced the heat exchange property of heat exchanger.The installation of dividing plate 3 is the otch that radially cut out a semicircle along header, and dividing plate 3 in otch is inserted into header, is made the circumference side of dividing plate 3 and the inwall of header connect airtight applying, and then welds it.Existing dividing plate as shown in Figure 2, its circumference side is smooth.When between dividing plate and the header space being arranged,,, also just can not guarantee the quality of heat exchanger so can't lean on visual or instrument detecting is come out because the space is to be hidden in header inside.
Summary of the invention
The objective of the invention is existing can't go out the defective that whether has the space between header and dividing plate by visual or instrument detecting in order to overcome, invent between a kind of circumference side that can make dividing plate and the header tube wall the space with extraneous communicate prevent interior leakage header dividing plate.The main feature of this dividing plate is that the circumference side of single layer separator is provided with groove, or be provided with the gap between two demarcation strips, when having the space between dividing plate and the header, the space can be passed through in heat exchanger inside, communicate with atmosphere via groove on the dividing plate or gap, the inner situation about communicating with atmosphere of heat exchanger can be tested out by the helium leak test link, has so just avoided the problem heat exchanger to dispatch from the factory.
The objective of the invention is to realize as follows:
The described anti-interior header dividing plate that leaks, it is characterized in that: it comprises a single layer separator, the circumference side of single layer separator has groove.
The section of described groove is triangle, rectangle, square or semicircle.
The described anti-interior header dividing plate that leaks, it is characterized in that: it comprises two demarcation strips, and wherein the single face of a demarcation strip is provided with a plurality of contour boss, and two demarcation strips are clipped in the middle boss, make between two demarcation strips and leave the gap.
Described boss is round boss, bar shaped boss or rectangular boss.
The described anti-interior header dividing plate that leaks, it is characterized in that: it comprises two demarcation strips, and wherein the single face of one or two demarcation strip has the taper platform, two demarcation strips are clipped in the middle the taper platform, make between two demarcation strips and leave the gap.
Good effect of the present invention is as follows: main feature of the present invention is that the circumference side of single layer separator is provided with groove, or be provided with the gap between two demarcation strips, when having the space between dividing plate and the header, the space can be passed through in heat exchanger inside, communicate with atmosphere via groove on the dividing plate or gap, the inner situation about communicating with atmosphere of heat exchanger can be tested out by the helium leak test link, has so just avoided the problem heat exchanger to dispatch from the factory.

The specific embodiment
As shown in Figure 3, the described anti-interior header dividing plate that leaks, it is characterized in that: it comprises a single layer separator 6, the circumference side of single layer separator 6 has groove 7.
The section of described groove 7 is triangle, rectangle, square or semicircle.
Shown in Figure 5 as Fig. 4, describedly leak the header dividing plate in anti-, it is characterized in that: it comprises two demarcation strips 8, wherein the single face of a demarcation strip 8 is provided with 9, two demarcation strips 8 of a plurality of contour boss boss 9 is clipped in the middle, and makes between two demarcation strips 8 and leaves the gap.
Described boss 9 is circular platform, bar shaped platform or rectangular platform.
As shown in Figure 6, it comprises two demarcation strips 8, and wherein the single face of one or two demarcation strip 8 has 10, two demarcation strips 8 of taper platform taper platform 10 is clipped in the middle, and makes between two demarcation strips 8 and leaves the gap.
Main feature of the present invention is that the circumference side of single layer separator is provided with groove, or be provided with the gap between two demarcation strips, when having the space between dividing plate and the header, the space can be passed through in heat exchanger inside, communicate with atmosphere via groove on the dividing plate or gap, the inner situation about communicating with atmosphere of heat exchanger can be tested out by the helium leak test link, has so just avoided the problem heat exchanger to dispatch from the factory.
