Abstract

The utility model relates to a core body structure for an efficient heat-exchanger. A pair of end sockets and a plurality of pairs of sealing strips are arranged at the two ends of a core body respectively, the sealing strip and the end sockets are fixedly connected into a whole, and the upper side and the lower side of each sealing strip are fixedly connected with separation plates. The core body structure for the efficient heat-exchanger is characterized in that a plurality of reinforcing ribs are evenly distributed between each pair of sealing strips, fins are respectively 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 layer of separation plate and the lower layer of separation plate are fixedly connected into a whole, and the lateral wall, fixedly connected with the corresponding end socket, of each sealing strip is provided with a concave groove. The core body structure for the efficient heat-exchanger is simple in structure, high in reliability and capable of effectively preventing the separation plates from breaking, and inner passages are good in sealing performance.

Description

A kind of high-performance heat exchanger core

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; In some high-tension apparatus environment, 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 separation, cause product leakage.This phenomenon is easier to occur in larger volume product, and the larger this phenomenon of volume is more obvious.

Utility model content

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 that dividing plate and fin are by spalling, 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, the upper and lower both sides of strip of paper used for sealing 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 and upper and lower two-layer dividing plate are fixed on one; 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 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, 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, internal channel leakage; Reinforcement between two relative strip of paper used for sealings is divided into some parts by fin, and the intensity that not only can increase dividing plate can also prevent that fin and dividing plate are by spalling, effectively Leakage prevention.

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, 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 upper and lower two-layer dividing plate 4, reinforcement 5 is divided into some parts by 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 high pressure spalling, occur the risk of leaking; 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.
