Abstract

The utility model relates to a core body for a high pressure resistance heat exchanger. The two ends of the core body are respectively provided with a pair of sealing heads and a plurality pairs of of sealing strips, the sealing strips and the sealing heads are fixedly connected into a whole, the upper sides and the lower sides of the sealing strips are fixedly connected with partition plates, and fins are arranged between the two sealing strips in every pair of sealing strips. The side walls where the sealing strips and the sealing heads are fixedly connected are provided with grooves, the side walls where the sealing strips and the fins are opposite are provided with arc-shaped grooves, and the outer edges of the arc-shaped grooves are provided with convex parts. The core body for the high pressure resistance heat exchanger is simple in structure, high in reliability, capable of effectively preventing the partition plates from being broken and preventing an inner channel from leaking.

Description

A kind of high pressure resistant heat exchanger core body

Technical field

The utility model 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 utilization comparatively widely in compressor industry of present stage plate-fin heat exchanger, but in use also there is weak point in the heat exchanger that some profiles are larger, large heat exchanger is in use larger owing to importing and exporting the temperature difference, 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 addition in the environment of some high pressure, because the weld seam of end socket and core body does not permeate, weld strength is inadequate, in the time of can not bearing larger pressure, causes weld seam to be torn, 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 burnt.

Utility model content

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

A high pressure resistant heat exchanger core body, the two ends of described core body are respectively with a pair of end socket and some to strip of paper used for sealing, and strip of paper used for sealing and end socket are fixed with one, and the upper and lower both sides of strip of paper used for sealing and dividing plate are connected, and each is to being provided with fin between two strip of paper used for sealings in 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 strip of paper used for sealing sidewall.

The beneficial effects of the utility model are: fluted with the sidewall band of fine weldering place of end socket on strip of paper used for sealing, while being beneficial to fine weldering, weld seam can permeate, and increases weld strength, increases the reliability of core body, reduces the risk of leaking; Simultaneously a strip of paper used for sealing side relative to fin 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 there is certain stress deformation simultaneously, prevent that dividing plate from rupturing, internal channel leakage.

Accompanying drawing explanation

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

Fig. 3 is structural representation of the present utility model.

The specific embodiment

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

As shown in Figure 1 to Figure 3, the two ends of core body described in the utility model 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 Shang Xia 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 strip of paper used for sealing 2; 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 to fibre weldering, is beneficial to the infiltration of welding fluid, and the intensity of increase weld seam, makes commissure not be prone to the defect of leakage, and when weld seam bears larger pressure, weld seam is also difficult for tearing; Strip of paper used for sealing 2 sidewall relative with 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, by 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 used time, can deform, and prevents dividing plate 4 fractures, there is the defect that internal channel leaks, 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 to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
