Abstract

The invention relates to a core for a high-pressure-resistant heat exchanger. A pair of seal heads and a plurality of pairs of seal strips are respectively arranged at two ends of a core body of the core, the seal strips are fixedly and integrally connected with the seal heads, the upper side and the lower side of each seal strip are fixedly connected with partition plates, and fins are arranged between each two corresponding seal strips; a groove is formed in the side wall, which is fixedly connected with the corresponding seal head, of each seal strip, an arc-shaped groove is formed in the side wall, which is opposite to the corresponding fins, of each seal strip, and protrusions are arranged at the outer edge of each arc-shaped groove. The core has the advantages that the core is simple in structure and high in reliability, and breakage of the partition plates and leakage of internal channels can be effectively prevented.

Description

A kind of high pressure resistant heat exchanger core body

Technical field

The present invention relates to technical field of heat exchangers, especially a kind of core body that is applied to large cube of compressor heat exchanger.

Background technology

The existing comparatively widely utilization in the compressor industry of present stage plate-fin heat exchanger, but weak point has in use also appearred in the heat exchanger that some profiles are larger, large heat exchanger is in use because the import and export temperature difference is larger, core body end strip of paper used for sealing and dividing plate place stress are concentrated, thermal deformation is serious, sometimes even cause dividing plate fracture, internal channel produces seepage.In the environment of some high pressure, because the weld seam of end socket and core body does not permeate, weld strength is inadequate, causes weld seam to be torn in the time of can not bearing larger pressure in addition, and product leakage lost efficacy; Strip of paper used for sealing and dividing plate fibre are welded in one, the close together of fin and strip of paper used for sealing, and fin is easily by scaling loss.

Summary of the invention

The applicant provides a kind of high pressure resistant heat exchanger core body for above-mentioned shortcoming of the prior art, and it is simple in structure, and reliability is high, can effectively prevent the dividing plate fracture, and internal channel leaks.

A kind of high pressure resistant heat exchanger core body, with a pair of end socket and some to strip of paper used for sealing, strip of paper used for sealing and end socket are fixed with one respectively at the two ends of described core body, and both sides and dividing plate are connected about the strip of paper used for sealing, and each is to being provided with fin between two strip of paper used for sealings in the strip of paper used for sealing; The sidewall band that strip of paper used for sealing and end socket are connected is fluted, and the strip of paper used for sealing sidewall relative with fin is with arc groove, and the outward flange of arc groove is with protuberance;

Preferably, the top of protuberance is higher than the strip of paper used for sealing sidewall.

Beneficial effect of the present invention is: fluted with the sidewall band of fine weldering place of end socket on the strip of paper used for sealing, weld seam can permeate when being beneficial to fine weldering, increases weld strength, increases the reliability of core body, reduces the risk of leaking; Simultaneously the relative side with fin of strip of paper used for sealing is with arc groove, and the edge of arc groove is outwardly,, can carry out fin spacingly, prevent that fin and end socket fibre are welded in one, also can make strip of paper used for sealing have certain stress deformation simultaneously, prevent that dividing plate from rupturing, the internal channel leakage.

Description of drawings

Fig. 1 and Fig. 2 are the three-dimensional structure diagram of strip of paper used for sealing of the present invention.

Fig. 3 is structural representation of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.

As shown in Figure 1 to Figure 3, the two ends of core body of the present invention are respectively with a pair of end socket 1 and some to strip of paper used for sealing 2, and strip of paper used for sealing 2 is fixed with one with end socket 1, strip of paper used for sealing about in the of 2 both sides and dividing plate 4 be connected, each is to being provided with fin 3 between two strip of paper used for sealings 2 in the strip of paper used for sealing 2; The sidewall band that strip of paper used for sealing 2 and end socket 1 are connected is fluted 21, when strip of paper used for sealing 2 and end socket 1 are carried out fibre weldering, is beneficial to the infiltration of welding fluid, and the intensity of increase weld seam makes the commissure not be prone to the defective of leakage, and weld seam also is difficult for tearing when weld seam bears larger pressure; The relative sidewall of strip of paper used for sealing 2 and fin 3 is with arc groove 23, the outward flange of arc groove 23 is with protuberance 22, and protuberance 22 can carry out fin 3 spacing, prevents when fibre welds, with fin 3 scaling loss, the adaptability to changes that arc groove 23 can make strip of paper used for sealing 2 be subject to dividing plate 4 is done the time spent, can deform, and prevents dividing plate 4 fractures, the defective that internal channel leaks appears, arc groove 23 has also increased area of dissipation, has reduced the resistance of wind, has improved the radiating efficiency of heat exchanger.

More than describing is explanation of the invention, is not that limited range of the present invention within protection scope of the present invention, can be done any type of modification referring to claim to the restriction of invention.

Claims
