Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As Figure 1-Figure 4, a kind of mouth organ passage parallel flow heat exchanger, comprise upper tank 1, lower header 2, and the hot channel 3 between two hydroeciums, described hydroecium is connected with inlet pipeline 4 and outlet pipeline 5, described upper 1, lower header 2 is pancake, and upper 1, lower header 2 upper surface is all provided with the connecting hole 7 of several symmetries; Described hot channel 3 is also pancake, and both sides are elbow structure 6, and described elbow 6 inserts in connecting hole 7, and this elbow 6 and connecting hole are for working in coordination; Described hot channel 3, near the lower surface of elbow, is fitted with the upper surface of hydroecium;
Refrigerant flow path is formed between upper tank 1, hot channel 3 and lower header 2; Refrigerant enters from inlet pipeline 4, through hot channel 3, flows out from outlet pipeline 5.
Innovative point of the present utility model is, the hot channel 3 solving existing electric automobile heat exchanger is few with hydroecium solder side, the problem of easily leaking.By the structure that elbow 6 is connected with hydroecium, increase solder side.Be specially connecting hole and be arranged to the size suitable with the elbow 6 of hot channel 3 two sections, when assembling, elbow 6 is loaded in connecting hole 7, welds in the edge of connecting hole 7, this is first place's solder side; Because pancake hot channel 3 is fitted with pancake hydroecium upper surface, also weld at both edges, junction, this is second place's solder side; The solder side that both add up is far longer than existing solder side, makes more firm, avoids the phenomenon occurring leaking.
Described connecting hole 7 inside edge is rounding structure, and the elbow junction of described hot channel 3 is corresponding rounding structure.
Described elbow structure 6 is 90 ° with hot channel.The utility model is preferably the angle of 90 °, and another effect of this angle can be easy to assembling exactly, meanwhile, can play best heat transfer effect.
Described hot channel 3 is multi-channel pipeline, and this hot channel 3 cross section is flat mouth organ shape.It is pointed out that the hot channel 3 of mouth organ shape is not equivalent to combine with existing multiple flat tube, those skilled in that art simply can not release the hot channel of mouth organ shape from multiple flat tube.Those skilled in that art can be used as hot channel with flat tube, and applicant has paid long creative work, and final design has gone out the hot channel of this mouth organ shape.
The hot channel 3 of mouth organ shape is for multiple flat tube, first rate of heat exchange is higher, suppose to reach the effect of ten flat tubes mutually arranged side by side, the hot channel of mouth organ shape only needs single hot channel 3 li to open ten mouth organ holes, heat exchanger effectiveness is higher, the tributary that fluid partitioning becomes several tiny, heat exchanger effectiveness can significantly higher than the fluid do not shunted.
Secondly, reach identical heat exchange effect, hot channel 3 materials of mouth organ shape are more economized, can be cost-saving greatly, and structure can be more simple, is easy to assembling.
The material of described hot channel 3 is preferably ENAW-3003, and surface is without composite bed.The pipeline of this material is applicable to processing, is easy to the shaping of mouth organ shape, and material is comparatively light simultaneously, alleviates the weight of whole heat exchanger.
Described hot channel 3 is single, is because will fit with battery surface.The effect that single mouth organ shape hot channel 3 is main is also under identical heat exchanger effectiveness, single can implementation structure simpler, cost is lower, meanwhile, the effect that quality is lighter.
The altitude range of described hot channel 3 bore is 1 ~ 5mm, and width range is 30 ~ 80mm.These height and the width change with radiator specification.
The flow of refrigerant direction of this heat exchanger is: flow into from inlet pipeline 4, through upper tank 1, cold-producing medium enters from the entrance point in first group of refrigerant flow path loop, respectively by the mouth organ shape pipeline of hot channel 3, upper 1 lower header 2 is all provided with dividing plate, due to the existence of dividing plate, therefore can only flow to single hot channel 3, when cold-producing medium arrives lower header 2, also due to the existence of dividing plate, another hot channel 3 reciprocal can only be flowed to, so, be back to again upper tank 1; Due to last group of refrigerant flow path loop the port of export through upper tank 1 with after the entrance point in refrigerant flow conduit loop of a group be communicated with, similar, the second, three group of refrigerant flow path loop is also such flow direction, last cold-producing medium completes heat exchanging process, flows out from outlet pipeline 5.Meanwhile, cold-producing medium is compared with cooling fluid, and under identical heat exchanger effectiveness, flow is less, and pressure is less.
The utility model also can have two identical heat exchangers to be formed in parallel, and uses same water inlet and delivery port, makes refrigerant flow direction two inlet pipelines by flow divider 8, then flow to two heat exchangers respectively and carry out heat exchange.
Described upper 1, lower header 2 all comprises upper cover 9 and lower cover 10, and described upper cover 9 medial surface and lower cover 10 lateral surface are fitted.
Described connecting hole 7 is arranged on upper cover 9, is provided with several flow-disturbings hole 11 bottom described lower cover 10.The effect in flow-disturbing hole 11 increases fluid resistance, thus add the efficiency of heat exchange, and flow-disturbing hole 11 can be the projection of small cylindrical, also can be the projection of other arbitrary shapes, the preferred small cylindrical of the utility model.Certainly, the arrangement mode in flow-disturbing hole 11 is uniform intervals arrangement, and spacing is between 11.6mm-12.6mm, and this spacing can reach maximum heat exchange efficiency.
Every technical staff's notice: although the utility model describes according to above-mentioned embodiment; but utility model thought of the present utility model is not limited in this utility model; the repacking of any utilization the utility model thought, all will include in this patent scope of patent protection.
