Description

One has heating plate type heat exchanger

Technical field:

This utility model relates to heat exchange equipment technical field, more specifically to one to be had Heating plate type heat exchanger.

Background technology:

Heat exchanger is parts critically important in refrigeration plant, and it is as vaporizer or condenser Use.Using heat exchanger as vaporizer in use, its outer wall can produce frosting to existing refrigerator Etc. problem, of long duration, the outer wall of vaporizer can amass full frost etc., thus reduces refrigerator inside The volume in space, meanwhile, also can affect the heat exchange of vaporizer, and reduce the use longevity of refrigerator Life, now, it is necessary to carrying out defrost, existing defrost mode is, in the adjacent bit of vaporizer Put installation heater, after heating devices heat, by air heat transfer and thermal-radiating side Formula so that be heated outside vaporizer, thus carry out defrost, its defrost effect is limited, Er Qiejia Thermal is necessarily mounted at heat exchanger adjacent regions, and it takes up room greatly, and designs trouble.

Utility model content:

The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that one has heating plate Formula heat exchanger, the mode that heating plate is combined by it with heat exchanger, space can be greatly reduced Taking, heat exchanger can run into the problem of frosting during using, given play to should have for heat exchanger Effect, need to carry out defrost, when frosting, heating plate directly or indirectly conducts heat to wing On sheet and flat tube, thus quickly realize defrost, it is ensured that heat exchanger properly functioning.

This utility model solves the scheme of described technical problem:

One has heating plate type heat exchanger, including flat tube, on the relative outer wall of described flat tube Being fixed with radiating fin, heating plate is clamped between two radiating fins.

One end of described flat tube connects feed tube, and the other end of flat tube connects drain pipe.

Described radiating fin is ripple bending-like.

Described radiating fin trapezoidal ripple bending-like, it includes multiple trapezoidal portion, adjacent two Having horizontal bending part between trapezoidal portion, described trapezoidal portion includes two oblique plate bodys, and two tiltedly There is between the top of plate body top connecting portion, there is at the two ends of oblique plate body multiple ventilation Hole.

Described heating plate includes tabular housing, is inserted with resistance wire in tabular housing, resistance wire Tabular housing is stretched out in the electrical heating wire wiring that two are provided with, and fills between resistance wire and tabular housing There is magnesia powder.

The S-shaped coiling of described flat tube, it includes multiple horizontal part, between adjacent two horizontal parts There is U-shaped bending part.

Described flat tube is micro-channel flat, and it has multiple opening.

All it is welded with radiating fin on the upper lateral wall of described horizontal part and lower lateral wall, adds Hot plate welding is on two corresponding radiating fins.

Described flat tube is formed by connecting by one or more little flat tube.

The left and right sides of flat tube is all stretched out in the both sides of described radiating fin, the oblique plate of radiating fin There is at the part of the left and right sides that body stretches out flat tube multiple air vent.

Prominent effect of the present utility model is:

Compared with prior art, heating plate is combined by it with heat exchanger, thus greatly reduces sky Between take, it is directly or indirectly conducted heat on flat tube by heater plate, thus Quickly realize defrost, it is ensured that heat exchanger properly functioning, its radiating fin has meanwhile Air vent can make radiating fin be difficult to frosting, also reduces the time of follow-up defrost, improves defrost Effect.

Detailed description of the invention:

Embodiment, is shown in as shown in Figures 1 to 6, and one has heating plate type heat exchanger, including Flat tube 10, the relative outer wall of described flat tube 10 is fixed with radiating fin 20, heating plate 30 are clamped between two radiating fins 20.

Further, one end of described flat tube 10 connects feed tube 1, another of flat tube 10 End connects drain pipe 2.

Further, described radiating fin 20 is in ripple bending-like.

Further, described radiating fin 20 trapezoidal ripple bending-like, it includes multiple Trapezoidal portion 21, has horizontal bending part 22, described trapezoidal portion between adjacent two trapezoidal portions 21 21 include two oblique plate bodys 23, have top and connect between the top of two oblique plate bodys 23 Portion 24, has multiple air vent 25 at the two ends of oblique plate body 23.

Further, described heating plate 30 includes tabular housing 31, in tabular housing 31 Being inserted with resistance wire 32, plate is stretched out in the electrical heating wire wiring 33 that two of resistance wire 32 are provided with Shape housing 31, be filled with between resistance wire 32 and tabular housing 31 magnesia powder 34 or other Insulant.

Further, the described S-shaped coiling of flat tube 10, it includes multiple horizontal part 11, Between adjacent two horizontal parts 11, there is U-shaped bending part 12.

Further, described flat tube 10 is micro-channel flat, and it has multiple opening.

Further, on the upper lateral wall of described horizontal part 11 and lower lateral wall, all welding are solid Surely radiating fin 20, heating plate 30 is had to be welded on two radiating fins 20 of correspondence.

Further, described flat tube 10 is formed by connecting by one or more little flat tube.

Further, the left and right sides of flat tube 10 is all stretched out in the both sides of described radiating fin 20, Meanwhile, radiating fin 20 can also partly stretch out or not stretch out flat tube 10；Radiating fin 20 Oblique plate body 23 left and right sides of stretching out flat tube 10 part at there is multiple air vent 25.

In use, use when normal, enter refrigeration working medium by feed tube 1, at flat tube Absorbing heat after flowing in 10, thus externally lower the temperature, then refrigeration working medium is from drain pipe 2 Discharge, and owing to all stretching out the both sides of flat tube 10 in the two ends of radiating fin 20, and have at two ends There is air vent 25, so that be not easy frosting at air vent 25, so that heat exchanger is not Easily frosting, and when deployed between long after, after heat exchanger outer wall frosting, pass through heating plate The resistance wire 32 of 30 heats, and thus makes heating plate 30 heat, and heating plate 30 is by heat Flat tube 10 is directly or indirectly passed to so that flat tube 10 is heated by radiating fin 20, from And outside frost is melted, its thawing is effective, and heating plate 30 will not take it His space, reduces the taking of overall space of heat exchanger.

Wherein, using the heat exchanger that the structure of the present embodiment is made, it can increase and decrease as required Heating plate 30, thus adapt to heat required amount, such as can be outside the flat tube 10 of part Between two radiating fins 20 on wall, heating plate 30 is set, it is not necessary to the phase of all flat tubes 10 To outer wall on heating plate 30 is set between the radiating fin 20 that is fixed with.

Finally, embodiment of above is merely to illustrate this utility model, and not new to this practicality The restriction of type, about the those of ordinary skill of technical field, without departing from essence of the present utility model In the case of god and scope, it is also possible to make a variety of changes and modification, the most all equivalents Technical scheme falls within category of the present utility model, and scope of patent protection of the present utility model should be by Claim limits.
