Description

Technical Field

[0001] The utility model relates to the technical field of alternative composite plates, in particular to a cold plate heat exchanger with a false flow channel airtight detection structure. Background Art

[0002] The current profile-type cold plate heat exchangers need to extrude the profile. Considering the production cost, a hollow false flow channel is made in the middle of the profile. These flow channels cannot be detected at present, which will cause internal leakage of the product, resulting in failure of the heat exchanger and reduced product yield. Utility Model Content

[0003] The utility model aims to provide a cold plate heat exchanger with a false flow channel airtight detection structure to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cold plate heat exchanger with a false flow channel airtight detection structure, comprising a heat exchanger body, wherein both ends of the heat exchanger body are respectively provided with a first packaging block and a second packaging block fixedly connected thereto, and one end of the heat exchanger body close to the second packaging block is respectively provided with a medium inlet pipe and a medium outlet pipe, and a through hole is provided on one side of the medium outlet pipe.

[0005] For further optimization, the tops of the medium inlet pipe and the medium outlet pipe are both provided with flexible connecting pipe openings.

[0006] For further optimization, the heat exchanger body is formed of a hollow plate, and a plurality of flow channels are symmetrically arranged inside the plate at equal distances.

[0007] For further optimization, a dummy flow channel is provided on one side of the plurality of flow channels close to the medium outlet pipe, and the through hole is connected with the dummy flow channel.

[0008] Further optimized, the heat exchanger body is composed of a hollow plate consisting of an upper plate and a lower plate of equal size, and its internal cavity is symmetrically provided with a plurality of isolation plates, and a plurality of flow channels are formed between the plurality of isolation plates.

[0009] Beneficial Effects

[0010] The utility model provides a cold plate heat exchanger with a false flow channel airtight detection structure. By drilling a hole at the false flow channel, if bad cross-flow occurs during airtight detection, the false flow channel has a through hole, which will cause internal leakage to become external leakage. At this time, the airtight instrument can complete the detection. After the detection is completed, we block the hole by welding. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0014] Example

[0015] like Figure 1-2 As shown, a cold plate heat exchanger with a false flow channel airtight detection structure includes a heat exchanger body 1, and a first packaging block 2 and a second packaging block 3 fixedly connected thereto are respectively provided at both ends of the heat exchanger body 1, and a medium inlet pipe 4 and a medium outlet pipe 5 are respectively provided at one end of the heat exchanger body 1 close to the second packaging block 3, and a through hole 6 is provided on one side of the medium outlet pipe 5.

[0016] In this embodiment, the tops of the medium inlet pipe 4 and the medium outlet pipe 5 are both provided with flexible connecting pipe openings 7, through which the medium input device is more tightly connected to avoid medium leakage.

[0017] The heat exchanger body 1 is made of a hollow plate, and a plurality of flow channels 8 are symmetrically arranged inside the plate at equal distances. A dummy flow channel 9 is arranged on one side of the plurality of flow channels 8 close to the medium outflow pipe 5 , and the through hole 6 is connected to the dummy flow channel 9 .

[0018] The heat exchanger body 1 is composed of a hollow plate consisting of an upper plate and a lower plate of equal size, and its internal cavity is symmetrically provided with a plurality of isolation plates 10, and a plurality of flow channels 8 are formed between the plurality of isolation plates 10. The heat exchange function of the cold plate heat exchanger is realized through the plurality of flow channels 8. Holes are punched at the false flow channels, and the size of the through holes is 5.0 mm. If bad cross-flow occurs during the airtightness test, the through holes set in the false flow channels will cause the internal leakage to become external leakage. At this time, the airtightness instrument can complete the test. After the test is completed, the through hole is blocked by welding to complete the test.
