Abstract
A heat exchanger of an automobile heater is mainly used for an automobile and is characterized by comprising a water pipe connector, a water chamber, flat pipes, fins, and a protecting plate. An inner erosion resistant coating is adhered on the surface of the inner layer of each flat pipe. An outer erosion resistant coating is adhered on the surface of the outer layer of each flat pipe. The fins are located in gaps formed by adjacent flat pipes and are respectively connected with the flat pipes. The flat pipes are welded pipes, and ports of the flat pipes are formed in a welding mode by adoption of high-frequency welding technology. Welding lines of the ports are provided with outer erosion resistant coatings in an adhering mode. The section of each flat pipe is flat. The face, connected with each fin, of each flat pipe is a plane. Two ends of each flat pipe are arc-shaped faces. The heat exchanger of the automobile heater has the advantages of being simple in structure, small in size, light in weight, good in stability, corrosion resistant, and incapable of causing any damage to the inner erosion resistant coatings due to utilization of high-frequency welding tubes, and avoiding direct contact between high-temperature media and flat pipe substrates.
Description
Technical field
The utility model relates to a kind of heat exchanger, particularly relates to a kind of car heater heat exchanger that is mainly used in automobile.
Background technology
In at present traditional air conditioning for automobiles, its heater design of heat exchanger adopts copper-tube aluminium chip heat exchanger mostly, this kind heat exchanger volume is large, weight is high, under the equal volume heat exchange efficiency low, use the characteristics such as material is many, processing technology is complicated, and after adopting this kind heat exchanger to grow up to be a useful person, easily cause the evaporimeter volume to increase, the structural member thickening, and the indoor limited space of car steering, when assembling the evaporimeter of traditional heat exchangers manufacturing, affect cabin space, sense of depression is arranged, in addition the impression driver take driving.
Indivedual heaters adopt the aluminium heat-exchange device on the domestic automobile, but the flat tube in the aluminium heat-exchange device all adopts the processing technology of pushing, and the anti-corrosion layer that add on the flat tube surface is after extruding, and not only hard to bear corrosion, and service life is shorter, and is easily impaired.This mainly is because the medium in the heater is engine cooling water, and contains different compositions in the current, at high temperature, aluminium flat is suffered erosion.Time has been grown, and causes the problems such as aluminium flat leakage, and is serious even jeopardize by bus personal security.
The utility model content
The purpose of this utility model just provide a kind of simple in structure, volume is little, lightweight, good stability, corrosion resistant car heater heat exchanger.
Solution of the present utility model is such: comprise water pipe head, hydroecium, flat tube, fin, backplate, the internal layer surface of described flat tube is stained with the anti-anticorrosive coat of internal layer, the superficies of described flat tube are stained with outer anti-anticorrosive coat, described fin is positioned at the gap that forms between adjacent flat tube, joins with flat tube respectively.
Further, described flat tube is welded pipe, and its interface adopts the high-frequency induction welding technique welding fabrication, and its weld seam is stained with outer anti-anticorrosive coat.
Further, the cross section of described flat tube is flat, with the fin joint face be the plane, two ends are arcwall face.
The utility model has the advantages that simple in structure, volume is little, lightweight, good stability, corrosion-resistant, uses ratio-frequency welded tube, can not cause any breakage to the internal layer anticorrosive coat, has avoided high-temperature medium to contact with the direct of flat tube base material.
Description of drawings
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is structural representations of flat tube 3 in the utility model.
The specific embodiment
As shown in Figure 1, the present embodiment comprises water pipe head 1, hydroecium 2, flat tube 3, fin 4, backplate 5, the internal layer surface of described flat tube 3 is stained with the anti-anticorrosive coat 6 of internal layer, the superficies of described flat tube 3 are stained with outer anti-anticorrosive coat 7, described fin 4 is positioned at the gap of 3 formation of adjacent flat tube, joins with flat tube 3 respectively.
As shown in Figure 2, the cross section of described flat tube 3 is flat, with fin 4 joint faces be the plane, two ends are arcwall face, and described flat tube 3 is welded pipe, and its interface adopts the high-frequency induction welding technique welding fabrication, weld bond is positioned at the arcwall face place, and its weld seam is stained with outer anti-anticorrosive coat 7.
Certainly, the present embodiment only is to specify of the present utility model; be not to restriction of the present utility model, for the those of ordinary skill in the industry, in the situation that need not creative work; the technical scheme that can both associate all should be protection domain of the present utility model.
