Further, feed tube joint and escape pipe joint lay respectively at the two ends of core body.
Further, knockout is connected with a compressor of air conditioner condenser, and mixing tube is connected with a compressor of air conditioner air entry.
Further, described two core bodys form 35 ° angle.
Further, described upper header and lower header are horizontally disposed, and described flat tube is vertical with described upper header.
Further, be respectively arranged with at least one dividing plate in described upper header and the lower header, any one described dividing plate all between two adjacent flat tubes, the formation runner that repeatedly commutates in header and the lower header on the described dividing plate.
Further, described upper header, lower header, flat tube, end cap, fin and dividing plate consist of by the aluminium alloy plate.
The utility model and prior art are compared, and its effect is actively with obvious.The utility model utilizes the aluminium alloy plate to consist of upper header, lower header, flat tube, end cap, fin and dividing plate, upper header, lower header, flat tube, end cap, fin and dividing plate consist of the evaporimeter of concurrent flow form, volume and the weight of heat exchanger have been alleviated, wind collateral resistance and refrigerant resistance have been reduced, increase heat exchange efficiency, improved simultaneously the efficiency of air-conditioning system.

The specific embodiment:
Embodiment 1:
As depicted in figs. 1 and 2, full aluminium parallel-flow evaporator of the present utility model, the core body 2 and the core body 8 that comprise same structure, core body 2 and core body 8 are inverted V-shape and are symmetrical arranged, comprise separately a upper header 11 in core body 2 and the core body 8, lower header 10 and a plurality of flat tube 12, in core body 2 and core body 8, upper header 11 and lower header 10 be arranged in parallel, flat tube 12 all is arranged between header 11 and the lower header 10, be provided with fin 13 between two flat tubes 12 of arbitrary neighborhood, the two ends of core body 2 and core body 8 are provided with side plate 15, lower header 10 and upper header 11 two ends are provided with end cap 3 separately, be positioned at an end of core body 2 and core body 8, end cap in lower header 10 is provided with feed tube joint 6, be positioned at the other end of core body 2 and core body 8, end cap at upper header 11 is provided with escape pipe joint 14, feed tube joint 6 is connected with capillary 5, the capillary 5 that core body 2 is connected with core body is connected with same knockout 4, knockout 4 is connected with the condenser of compressor of air conditioner, escape pipe joint 14 is connected with escape pipe 1, the escape pipe 1 that core body 2 is connected with core body is connected with same mixing tube 7, mixing tube 7 is connected with the compressor of air conditioner air entry, capillary 5, knockout 4, escape pipe 1 and mixing tube 7 are made of copper pipe.
Further, two core bodys 2 and 8 form 35 ° angle.
Further, upper header 11 and lower header 10 are horizontally disposed, and flat tube 12 is vertical with upper header 11, and fin 13 is vertical with flat tube 12.
Further, be respectively arranged with at least one dividing plate that deadens its inner chamber fully 9 in upper header 11 and the lower header 10, dividing plate 9 is between two adjacent flat tubes 12, and dividing plate 9 forms the runner that repeatedly commutates at upper header 11 and lower header 10, to increase the flow path of refrigerant.
Further, upper header 11, lower header 10, flat tube 12, end cap 3, fin 13, side plate 15, dividing plate 7 consist of by the aluminium alloy plate.
In the embodiment shown in Figure 2, the refrigerant flow direction marks with arrow.After the gas that coolant media becomes HTHP through compressor compresses enters condenser by pipeline, heat release is condensed into the liquid of cryogenic high pressure, liquid by throttling mechanism throttlings such as capillaries after, the gas-liquid mixture that becomes low-temp low-pressure flows into the evaporimeter evaporation of absorbing heat, the overheated gas of formation low-pressure low-temperature; Because refrigerant evaporation needs heat absorption, so that be pulled away by the airborne heat of evaporator external, thereby the air side temperature is reduced, reach refrigeration, and the overheated gas of low-pressure low-temperature enters compressor formation circulation.
