In the air-conditioning unit of second kind of technical scheme, described airduct import is positioned at outside the heat exchanger edge.
The utility model identical heat exchanger of outside two air inlets of blower fan both sides or air outlet, arranging, air inlet or air outlet keep equidistant apart from the both sides heat exchanger, and heat exchanger and air inlet or air outlet end face or tangent plane are parallel, center over against the heat exchanger of air inlet or air outlet overlaps with the axis of air inlet or air outlet, just can make the both sides heat exchanger obtain impartial heat exchange, and the air-flow of each stream of heat exchanger is distributed preferably, the deviation of inhomogeneities is less than 5% in each stream of heat exchanger; This arrangement mode can be with blower fan and heat exchanger and isolation of components settings such as refrigeration pipe, compressor, the process that makes return air enter blower fan is only passed through heat exchanger, need not to reduce the air intake resistance greatly through other refrigeration accessories, simultaneously also can reduce the insulation measure, thereby reduce cost.The utility model is that blower fan and heat exchanger structure are integrated, and the distribution that can be other refrigeration parts provides the bigger free degree, increases the design convenience, has further saved space and cost.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the schematic appearance of the utility model embodiment 1.
The specific embodiment
The heat exchanger 2 that is adopted in the present embodiment is flat heat exchanger, all is placed with identical heat exchanger 2 outside two air inlets 11 of blower fan 1 both sides, and promptly blower fan 1 is between two heat exchangers 2.Two heat exchangers 2 are all equal apart from the distance L of two air inlets 11 of blower fan 1 over against air inlet 11 and heat exchanger 2, described heat exchanger 2 is parallel with air inlet 11 end faces or tangent plane, overlaps with the axis of air inlet 11 over against the center of the heat exchanger 2 of air inlet 11.Above-mentioned blower fan 1 all can satisfy the heat exchange that both sides heat exchanger 2 obtains equalization with the arrangement mode of heat exchanger 2.
The opening of two air inlets 11 of present embodiment blower fan 1 is opposite, but the coincidence of the axis of air inlet 11, then two of blower fan 1 air inlet 11 outer heat exchangers 2 are parallel to each other.Because air inlet 11 centers are corresponding with heat exchanger 2 centers, and the air-flow of each heat exchanger 2 each stream is distributed preferably, correspondingly the deviation of inhomogeneities is just less in heat exchanger 2 each stream.
Described fan outlet is connected with airduct 3, the extended distance of fan outlet and air inlet 11 of airduct 3, the outlet of airduct 3 is arranged on top, below or the place ahead outside heat exchanger 2 edges, because airduct 3 outlets are positioned at outside heat exchanger 2 edges, can avoid the space between heat exchanger 2 that the return air problem of short-circuit takes place.
Concrete structure is: the fan outlet of blower fan both sides all is placed with identical heat exchanger outward, and promptly blower fan is between two heat exchangers.Two heat exchangers are all equal apart from the distance of the fan outlet of blower fan both sides over against fan outlet and heat exchanger, described heat exchanger is parallel with fan outlet end face or tangent plane, overlaps with the axis of fan outlet over against the center of the heat exchanger of fan outlet.The opening of the fan outlet of present embodiment blower fan both sides is opposite, but because the axis of fan outlet overlaps, then the outer heat exchanger of the fan outlet of the both sides of blower fan is parallel to each other.And, the air-flow of each each stream of heat exchanger is distributed preferably because the fan outlet center is corresponding with the heat exchanger center, correspondingly the deviation of inhomogeneities is just less in each stream of heat exchanger.
Described air inlet is connected with airduct, and the extended distance of fan outlet and air inlet of airduct because the airduct import is positioned at outside the heat exchanger edge, can avoid the space between heat exchanger that the return air problem of short-circuit takes place.
The shape of heat exchanger flat except among above-mentioned two embodiment also can be C type heat exchanger (heat exchanger is the semi-surrounding structure) or circulating type heat exchanger (heat exchanger encloses and covers a circle).The blower fan of these two kinds of structures is embedded in the space that heat exchanger surrounds, the part of heat exchanger inboard is all over against air inlet or fan outlet, and heat exchanger equates apart from the air inlet of blower fan or the distance of air outlet, described heat exchanger and air inlet or fan outlet end face or tangent plane are parallel, overlap with the axis of air inlet or fan outlet over against the center of the heat exchanger of air inlet or fan outlet.Fan outlet or air inlet are added by airduct too and grow to outside the heat exchanger edge, avoid the return air short circuit.
