Abstract

The utility model relates to a core for a compressor heat exchanger. The two ends of the core are respectively provided with a pair of sealing heads and a plurality of pairs of sealing bars, the sealing bars and the sealing heads are fixedly connected together, the upper sides and the lower sides of the sealing bars are fixedly connected with separation plates, and a fin is arranged between every two sealing bars. Grooves are formed in the side walls, fixedly connected with the sealing heads, of the sealing bars, and V-shaped protruding tips are arranged on the side walls, opposite to the fins, of the sealing bars. The core for the compressor heat exchanger is simple in structure, high in reliability and free of leakage.

Description

A kind of compressor 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, 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, cause weld seam to be torn, 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, thus easily separated by spalling, 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 compressor heat exchanger core body, and it is simple in structure, and reliability is high, without leaking.

A kind of compressor 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, 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, each is to being evenly equipped with reinforcement between two strip of paper used for sealings in strip of paper used for sealing, two ends and the dividing plate of reinforcement are fixed on one, between two reinforcements and between reinforcement and strip of paper used for sealing with fin; The sidewall band that strip of paper used for sealing and end socket are connected is fluted;

Preferably, the sidewall that strip of paper used for sealing is relative with fin is with V-arrangement spur.

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; A strip of paper used for sealing side relative to fin is with spur simultaneously, can carry out fin spacingly, prevent fin scaling loss, the reinforcement between two relative strip of paper used for sealings is divided into some parts by fin, 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 reinforcement 5 between two strip of paper used for sealings 2 in strip of paper used for sealing 2, the two ends of reinforcement 5 and dividing plate 4 are fixed on one, between two reinforcements 5 and between reinforcement 5 and strip of paper used for sealing 2 with fin 3, reinforcement 5 is divided into some parts by the fin 3 between two strip of paper used for sealings 2, not only make 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, there is 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, and the infiltration of profit and welding fluid, 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 V-

arrangement spur

22, and 22 pairs of fins of V-arrangement spur 3 carry out spacing, prevents when fibre welds, and fin 3 and end socket fibre are welded in to one, affect the reliability of fin 3, and then the radiating effect of assurance fin 3.

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.
