Description

A kind of band-tube type heat exchanger

Technical field

The utility model relates to a kind of heat exchanger, relates in particular to a kind of band-tube type heat exchanger.

Background technology

Traditional brazing plate type heat exchanger is a kind of heat exchanger being formed by a series of metal sheet closed assembly, solderings with bellows-shaped.The runner that forms many small circulation sections between each plate of composition heat exchanger, carries out exchange heat by plate, and it is compared with conventional shell and tube exchanger, and under identical flow resistance and pump power Expenditure Levels, its heat transfer coefficient will exceed a lot.But for traditional plate type heat exchanger, because space between two plates is little, fluid resistance is large, easily stop up, once stop up, just easily occur local or all lost efficacy, affect efficiency and even cause leakage.In addition, monolithic heat exchange area and the No. of plates of traditional brazing plate type heat exchanger are limited, can not meet the requirement of larger heat exchange amount, and expansibility is inadequate.

Summary of the invention

The utility model, for deficiency of the prior art, provides a kind of band-tube type heat exchanger, and the resistance between the plate of this heat exchanger is less, be difficult for stopping up, and the convenient expansion of plate.

In order to solve the problems of the technologies described above, the utility model by the following technical solutions:

A kind of band-tube type heat exchanger, comprise end plate, base plate, plate core passage and tube connector, described tube connector comprises the inlet pipe A being arranged on end plate, go out to manage A, inlet pipe B and be arranged on and go out to manage B on base plate, described end plate and base plate are welded on the two ends of plate core passage, described plate core passage is alternately stacking by some plate A and plate B, soldering forms, described plate A goes up with inlet pipe A and goes out to manage the corresponding position of A with plate B and offers medium through hole, on described plate A, be also provided with some boss, the upper position corresponding with boss of described plate B is also provided with concave station, the same position of the top of described boss and the bottom of concave station is all die-cut a through hole, the surrounding of described end plate, plate A, plate B and base plate is provided with sealing inclined-plane.

As preferably: form runner between first jiao of bore region, plate, second jiao of bore region and conduit region between described adjacent plate A and plate B, end plate and plate B form range of distribution, base plate and plate B formation collecting zone.

The utility model adopts above technical scheme, on the one hand, this band-tube type heat exchanger is in the stacking mode of plate, form the fluid passage of similar shell-and-tube heat exchanger, therefore, compared to traditional plate type heat exchanger, resistance between plate is less, be difficult for stopping up, plate can also infinitely extend on thickness direction, applicable to the larger application of changing heat demand.In addition on the one hand, the passage that this heat exchanger forms with the stacking soldering of some medium through hole on plate substitutes tubulation passage, therefore, compared to traditional shell pipe heat exchanger, had higher heat exchange efficiency, and shared volume is less, cost-saving.

The specific embodiment

Below in conjunction with accompanying drawing, the preferred embodiment of a kind of band-tube type heat exchanger of the utility model is made to detailed description:

As Fig. 1, a kind of band-tube type heat exchanger shown in Fig. 2, comprise end plate 100, base plate 500, plate core passage 400 and tube connector, described tube connector comprises the inlet pipe A101 being arranged on end plate 100, go out to manage A103, inlet pipe B102 and be arranged on and go out to manage B501 on base plate 500, described end plate 100 and base plate 500 are welded on the two ends of plate core passage 400, described plate core passage 400 is alternately stacking by some plate A200 and plate B300, soldering forms, described plate A200 goes up with inlet pipe A101 and goes out to manage the corresponding position of A103 with plate B300 and offers medium through hole 700, on described plate A200, be also provided with some boss 203, the upper position corresponding with boss 203 of described plate B300 is also provided with concave station 303, the same position of the bottom of the top of described boss 203 and concave station 303 is all die-cut a through hole 800, the surrounding of described end plate 100, plate A200, plate B300 and base plate 500 is provided with sealing inclined-plane 900.Between described adjacent plate A200 and plate B300, form between first jiao of bore region 601, plate runner 602, second jiao of bore region 603 and conduit region 605, end plate 100 forms range of distribution 604 with plate B300, and base plate 500 forms collecting zone 606 with plate B300.

During work, the inlet pipe A101 of medium 1 through being positioned at end plate 100 enters first jiao of bore region 601 by the medium through hole 700 of plate B300 and plate A200, then enter runner 602 between plate, finally come together in second jiao of bore region 603, from the A103 that goes out to manage of end plate 100, flow out.Medium 2 is entered by the through hole 800 that is positioned at plate B300 and plate A200 and is entered conduit region 605 by range of distribution 604 from being positioned at the inlet pipe B102 of end plate 100, finally comes together in collecting zone 606, and the B501 that goes out to manage through being positioned on base plate 500 flows out.
