Description

A kind of Novel pressure-resistant large scale heat exchanger

Technical field

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

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 Novel pressure-resistant large scale heat exchanger, its structure Simply, easy for installation, heat exchanger effect is good, high pressure resistant, production and processing low cost.

A kind of Novel pressure-resistant large scale 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, the second end socket and the welding of the 4th end socket in the two ends of the second core body V-shaped groove is carried in the solder side of one, the second end socket and the 4th end socket, and the back side of the solder side carries reinforcing plate, the Two end sockets are 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, two end socket welds arrange V-shaped groove, can permeate beneficial to weld seam during fine weldering, and the inner side of end socket arranges and adds Strong plate, prevents from splitting as the setting of V-shaped groove causes end socket weldering occur in fine weldering；

3rd, 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 Figures 1 to 4, 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, the second end socket 3 and the 4th in the two ends of the second core body 6 End socket 4 is welded in the solder side of one, the second end socket 3 and the 4th end socket 4 with V-shaped groove 8, and when being conducive to fibre to weld, weld seam can Infiltration, improves fibre and welds quality, and for preventing end socket weldering when being arranged on fine weldering of V-shaped groove 8 from splitting, the back side of the solder side carries and adds Strong plate 7, increased the intensity of end socket, and the second end socket 3 is communicated by connecting hole 9 with the 4th end socket 4；Preferably, the two of the first core body 5 End 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 51 in each pair of strip of paper used for sealing 51 it Between be evenly equipped with reinforcement 54, reinforcement 54 is of a lateral H shape, not only can also reduce resistance with material-saving, increase radiating surface Product, improves the radiating efficiency of heat exchanger, and the two ends of reinforcement 54 and dividing plate 52 are fixed on one, between two reinforcements 54 and Fin 53 is carried between reinforcement 54 and strip of paper used for sealing 51, and the fin 53 between two strip of paper used for sealings 51 is divided into several pieces by reinforcement 54, Fin 53 is more consolidated, the intensity of dividing plate 52 can also be increased, prevent fin 53 from being opened by high pressure spalling with dividing plate 52, go out The risk for now leaking；

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.
