Abstract

The invention relates to a core body structure for an efficient heat exchanger. The two ends of the core body are respectively provided with a pair of end sockets and a plurality of pairs of sealing strips, the sealing strips and the end sockets are fixedly connected into a whole, and partition boards are fixedly connected with the upper sides and the lower sides of the sealing strips. The core body structure for the efficient heat exchanger is characterized in that a plurality of reinforcing ribs are distributed between every two sealing strips in all sealing strips, fins are arranged among the reinforcing ribs and between the reinforcing ribs and the sealing strips, the section of each fin is rectangular, the reinforcing ribs, the upper partition boards and the lower partition boards are connected into a whole, and grooves are formed in the side walls, fixedly connected with the end sockets, of the sealing strips. The core body structure for the efficient heat exchanger is simple in structure, high in reliability, capable of effectively preventing the partition boards from being fractured and good in interior channel airtightness.

Description

A kind of high-performance heat exchanger core

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 utilization comparatively widely 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 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 the 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, causes weld seam to be torn in the time of can not bearing larger pressure, 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; When product needed is born larger pressure, because the contact-making surface of channel interior fin and dividing plate is less, thereby easily by spalling, separated in some high-tension apparatus environment, cause product leakage.This phenomenon is easier to occur in the larger volume product, the larger this phenomenon of volume is more obvious.

Summary of the invention

The applicant, for above-mentioned shortcoming of the prior art, provides a kind of high-performance heat exchanger core, and it is simple in structure, and reliability is high, can effectively prevent dividing plate and fin by spalling, the internal channel good airproof performance.

A kind of high-performance heat exchanger core, the two ends of described core body are respectively 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, strip of paper used for sealing both sides, up and down and dividing plate are connected, it is characterized in that: each is to being evenly equipped with some reinforcements between two strip of paper used for sealings in strip of paper used for sealing, and reinforcement is " work " shape, between reinforcement and between reinforcement and strip of paper used for sealing with fin, the cross section of fin is rectangular, and reinforcement is fixed on one with the two-layer dividing plate in up and down; The sidewall band that strip of paper used for sealing and end socket are connected is fluted;

Preferably, 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 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, prevents that fin and end socket fibre are welded in one, also can make strip of paper used for sealing have certain stress deformation simultaneously, prevents that dividing plate from rupturing, the internal channel leakage; Reinforcement between two relative strip of paper used for sealings is divided into some parts with fin, and the intensity that not only can increase dividing plate can also prevent fin and dividing plate by spalling, effectively Leakage prevention.

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, 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 evenly equipped with some reinforcements 5 between two strip of paper used for sealings 2 in strip of paper used for sealing 2, reinforcement 5 is " work " shape, can reduce the resistance of 5 pairs of wind of reinforcement or water, improves heat exchange efficiency; With fin 3, the cross section of fin 3 is rectangular between reinforcement 5 and between reinforcement 5 and strip of paper used for sealing 2, and the resistance of convection cell is little, and contact area is large, is beneficial to heat radiation; Reinforcement 5 is fixed on one with the two-layer dividing plate 4 in up and down, reinforcement 5 is divided into some parts with the fin 3 between two strip of paper used for sealings 2, not only makes fin 3 more firm, can also increase the intensity of dividing plate 4, prevent that fin 3 and dividing plate 4 from being opened by the high pressure spalling, the risk of leaking occurs; 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, make commissure not be prone to the defect of leakage, and weld seam also is difficult for tearing when weld seam bears larger pressure; 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, 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 used time, can deform, and prevents dividing plate 4 fractures, the defect 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.

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