Description

A kind of plate-fin heat exchanger

Technical field

The utility model relates to heat transmission equipment, relates in particular to a kind of plate-fin heat exchanger.

Background technology

Strip of paper used for sealing effect on heat exchanger is huge at present, strip of paper used for sealing often plays sealing and supporting role in plate-fin heat exchanger, and in the heat radiation fuse of whole heat exchanger, the weight of strip of paper used for sealing accounts for 8%, for strip of paper used for sealing and dividing plate contact-making surface are increased, the strip of paper used for sealing length of using will suitably extend, weight also can increase thereupon simultaneously, production cost also can correspondingly increase like this, so just increased the weight of the burden of enterprise greatly, the marketing of heat exchanging device also causes very big injury, how should guarantee the contact-making surface of strip of paper used for sealing and dividing plate, and effectively control production cost again becomes a difficult problem always.

Summary of the invention

The utility model is too big at the proportion of strip of paper used for sealing in heat radiation fuse weight of the plate fin type radiator that prior art exists, increase greatly production cost, increase the weight of the burden bearing capacity of enterprise, the problem that is difficult to adapt to the marketing of heat exchanger, a kind of simple in structure, plate-fin heat exchanger with novel strip of paper used for sealing of reducing cost is provided.

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

A kind of plate-fin heat exchanger, comprise shell, be installed in the fixed part that is used for fixing plate-fin heat exchanger on the shell, heat exchange fuse and be welded on the end socket cavity at heat exchange fuse two, be welded with inlet tube and outlet on the end socket cavity, the heat exchange fuse comprises outboard partition, inboard partition, inboard fin, inboard strip of paper used for sealing, outside fin, the side plate on outer seal and both sides, outside fin of placing between outboard partition and outboard partition and outer seal are formed outer tunnel, the inboard fin of placing between inboard partition and inboard partition, inboard strip of paper used for sealing is formed internal channel, the end socket cavity is connected with internal channel, described internal channel and external passage layered intersection are placed, and described outer seal has a recess away from an end of outside fin.This structure does not change the contact-making surface of outer seal and outboard partition, do not reduce support force, but outer seal weight significantly reduces yet.

Preferred as the best, the recess on the described outer seal is rectangle or is fan-shaped.This structure helps reducing the weight of outer seal most.

As preferably, described inboard strip of paper used for sealing has a thin recess away from an end of inboard fin.This structure does not change the contact-making surface of inboard strip of paper used for sealing and inboard partition yet, does not reduce support force yet, but inboard strip of paper used for sealing weight significantly reduces.

Preferred as the best, the triangular in shape or arc of described thin recess.This structure helps reducing the weight of inboard strip of paper used for sealing most.

According to the technical solution of the utility model, though do not change the contact-making surface of strip of paper used for sealing and dividing plate, do not reduce support force yet, but the weight of strip of paper used for sealing has reduced nearly 20%, cost also significantly descends, simultaneously simple in structure, alleviate the burden bearing capacity of enterprise greatly, adapted to the marketing of heat exchanger greatly.
