Description

A kind of new large scale oil gas heat exchanger

Technical field

This utility model is related to technical field of heat exchangers, especially the oil gas heat exchanger of large scale low cost.

Background technology

Plate-fin heat exchanger existing relatively broad utilization in compressor industry at this stage, but some profiles are larger changes Hot device also occurs in that weak point in use, and in the environment of some high pressure, the weld seam of end socket and core body does not permeate, weldering Seam insufficient strength, it is impossible to cause weld seam tear, product leakage to fail when bearing larger pressure, this phenomenon is in larger volume product In be easier to occur, the more big this phenomenon of volume is more obvious, and size is also high to manufacturing technique requirent greatly, increased the production of product Manufacturing cost.

Utility model content

The applicant is directed to above-mentioned shortcoming of the prior art, there is provided a kind of new large scale oil gas heat exchanger, its structure Simply, easy for installation, heat exchanger effect is good, production and processing low cost.

A kind of new large scale oil gas heat exchanger, including the first core body and the second core body, the two ends welding of the first core body the One end socket and the second end socket；Weld the 3rd end socket and the 4th end socket in the two ends of the second core body, it is characterised in that：Second end socket and Four end sockets are welded in one, and the second end socket is communicated by connecting hole with the 4th end socket；

Further technical scheme is as follows for this utility model：

Preferably, the two ends of the first core body are respectively provided with some to strip of paper used for sealing, and the upper and lower both sides of strip of paper used for sealing and dividing plate are connected, each to envelope Reinforcement is evenly equipped between two strip of paper used for sealings in bar, reinforcement is of a lateral H shape, the two ends of reinforcement are fixed on integrally with dividing plate, two Fin is carried between individual reinforcement and between reinforcement and strip of paper used for sealing；

Preferably, strip of paper used for sealing is fluted with the side cornice that the first end socket is connected.

The beneficial effects of the utility model are：

1st, large-sized core body is split into two core bodys individually carries out fine weldering processing, welds between two small size core bodys End socket communicate, thus reduce the production and processing difficulty of large scale core body, reduce the manufacturing cost of product；

2nd, fluted with the side cornice at end socket fibre weldering on strip of paper used for sealing, can permeate beneficial to weld seam during fine weldering, increase weld seam strong Degree, increases the reliability of core body, reduces the risk of leakage；Strip of paper used for sealing carries arc groove with fin opposite side simultaneously, and arc is recessed The edge of groove is outwardly, fin can be carried out spacing, prevents fin and end socket fibre to be welded in one, while strip of paper used for sealing can also had There is certain stress deformation, prevent dividing plate from rupturing, internal channel is leaked；Fin is divided into by the reinforcement between two relative strip of paper used for sealings Several pieces, the intensity that can not only increase dividing plate are also prevented from fin with dividing plate by spalling, effective prevent leakage.

Specific embodiment

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

As shown in Figure 1 to Figure 3, this utility model includes the first core body 5 and the second core body 6, the two ends welding of the first core body 5 First end socket 2 and the second end socket 3；Weld the 3rd end socket 1 and the 4th end socket 4 in the two ends of the second core body 6, it is characterised in that：Second End socket 3 and the 4th end socket 4 are welded in one, and the second end socket 3 is communicated by connecting hole 7 with the 4th end socket 4；Preferably, the first core body 5 Two ends be respectively provided with some to strip of paper used for sealing 51, strip of paper used for sealing about 51 both sides and dividing plate 52 be connected, two strip of paper used for sealings in each pair of strip of paper used for sealing 51 Reinforcement 54 being evenly equipped between 51, reinforcement 54 is of a lateral H shape, not only resistance can also being reduced with material-saving, increase dissipates Hot area, improves the radiating efficiency of heat exchanger, and the two ends of reinforcement 54 are fixed on one with dividing plate 52, between two reinforcements 54 And fin 53 is carried between reinforcement 54 and strip of paper used for sealing 51, the fin 53 between two strip of paper used for sealings 51 is divided into some by reinforcement 54 Part, fin 53 is more consolidated, the intensity of dividing plate 52 can also be increased, prevent fin 53 with dividing plate 52 by high pressure spalling Open, the risk of leakage occur；

Preferably, the side cornice fluted 55 that strip of paper used for sealing 51 and the first end socket 2 are connected, is carrying out fine weldering to strip of paper used for sealing 51 and end socket When, the infiltration of profit and welding fluid increases the intensity of weld seam, makes commissure be less prone to the defect of leakage, bear larger pressure in weld seam During power, weld seam is not easy to tear；The sidewall edge relative with fin 53 of strip of paper used for sealing 51 symmetrically carries V-arrangement spur 56, V-arrangement spur 56 pairs Fin simultaneously carries out spacing about 53, prevent in fine weldering, and any position of fin 53 is connect with the main body of dividing plate 52 and strip of paper used for sealing 51 Touch, fin 53 and end socket fibre are welded in one, affect the reliability of fin 53, and then ensure the radiating effect of fin 53.

Above description is to explanation of the present utility model, is not the restriction to utility model, and this utility model is limited Scope can make any type of modification referring to claim within protection domain of the present utility model.
