Abstract

The utility model discloses a double-flow heat exchanger which comprises a core, a left head, and right head. Two sides of the core are respectively fixedly connected with the left head and the right head. The left head is provided with a left liquid inlet and a left liquid outlet, and a gap is formed between the left liquid inlet and the left liquid outlet. The right head is provided with a right liquid inlet and a right liquid outlet, and a gap is formed between the right liquid inlet and the right liquid outlet. Insulation layers are coated on the outer sides of the heads and the core, and a metal net is wrapped in each insulation layer. The double-flow heat exchanger has the advantages of simple structure and fine mechanical property.

Description

A kind of Double-tube-pass heat exchanger

Technical field

The utility model relates to field of heat exchangers, relates in particular to Double-tube-pass heat exchanger.

Background technology

Existing Double-tube-pass heat exchanger, comprises core unit, and both sides are fixed with seal head, and the opposite side of end socket is provided with the first end socket and the second end socket, the first end socket and the second end socket homonymy and be arranged above and below; The first end socket and the second end socket are closely welded in core unit.When thermal medium enters heat exchanger by oil-in, temperature is very high, through dispelling the heat in heat exchanger, lower in the temperature in exit; Because oil inlet and outlet place end socket is closely welded on a place, because thermal stress coefficient is different, the thermal deformation causing is also different, very easily causes two end socket extruding, causes to seal with core body weld and tears, and impact is produced.

Utility model content

The purpose of this utility model is intended to overcome the defect of prior art, and a kind of Double-tube-pass heat exchanger is provided, have simple in structure, the feature of good mechanical property.

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

A kind of Double-tube-pass heat exchanger, comprise core body, left end socket, right end socket, it is characterized in that: described core body both sides are fixedly connected with respectively left and right end socket, wherein left end socket is provided with left inlet and left liquid outlet, gapped between left inlet and left liquid outlet, another right end socket is provided with right inlet and right liquid outlet, between right inlet and right liquid outlet, is provided with gap, described end socket and core body outside are enclosed with heat-insulation layer, in described heat-insulation layer, are enclosed with wire netting.

Described heat-insulation layer is polystyrene heat-preservation layer.

Described wire netting twine surface is provided with electrodeposited coating.

The utlity model has following beneficial effect:

When thermal medium enters heat exchanger by inlet, temperature is very high, through dispelling the heat in heat exchanger, temperature in exit is lower, inlet and liquid outlet present position are relatively far apart and be separated with U-shaped breach, make the thermal stress coefficient of two end sockets different, the distortion causing is not identical yet, avoids the extruding of end socket; End socket and core body are enclosed with heat-insulation layer, and the thermal efficiency improves, and has saved the energy; In heat-insulation layer, be enclosed with wire netting, mechanical performance strengthens, and is difficult for fragmentation, can effectively play a supporting role.
