Description
Technical field
The present invention relates to a kind of combined type multi-flow heat exchanger, can be used for the air-conditioner of vehicle.
Background technology
Know from prior art that the combined type multi-flow heat exchanger that is used for air conditioner for vehicles comprises the heat-transfer pipe and the fin of a plurality of overlappings.This known combined type multi-flow heat exchanger can be used as the evaporimeter of air conditioner for vehicles.Air conditioner for vehicles an urgent demand always reduces the space of the device that installs an air-conditioner.Therefore wish to make the depth dimensions of evaporimeter, promptly air flows through the size of direction, attenuation, and wish at the side surface of evaporimeter the coupling part to be set for the installing space that reduces evaporimeter, so that introduce or discharging refrigerant.Also wish air themperature equalization in addition, to produce high performance air-conditioner by evaporimeter.
Therefore.For depth dimensions attenuation that makes evaporimeter and the installing space that reduces evaporimeter, propose a kind of heat exchanger shown in Figure 9 among the day disclosure utility model communique No.H7-12778, proposed a kind of heat exchanger shown in Figure 10 among day disclosure utility model communique No.H9-17850.
As shown in Figure 9, heat exchanger 100 has epicoele 102 and cavity of resorption 103.Epicoele 102 and cavity of resorption 103 are communicated with by one group of pipeline 101.Epicoele 103 comprises upstream cavity 104 and the downstream cavity 105 of relative flow direction A '.The inner space of upstream cavity 104 has the chamber 107 and 108 that demarcation strip 106 is separated into.Equally, the inner space of downstream cavity 105 has the chamber 110 and 111 that demarcation strip 109 is separated into.The chamber 108 of upstream cavity 104 and the chamber of downstream cavity 105 111 are communicated with by passage 112.Cavity of resorption 103 comprises upstream cavity 113 and the downstream cavity 114 of relative air-flow direction A '.
At heat exchanger 100, the heat exchange medium that the fluid intake part 115 by being arranged on upstream cavity 104 chambers 107 is introduced flows through heat exchanger 100, as shown in Figure 9, discharges from the fluid issuing part 116 of the chamber 110 that is arranged on downstream cavity 105.
In addition, as shown in figure 10, heat exchanger 117 has epicoele 118 and cavity of resorption 119.Epicoele 118 and cavity of resorption 119 are communicated with by one group of pipeline 120.Epicoele 118 comprises relative air-flow direction A " upstream cavity 121 and downstream cavity 122.The inner space of upstream cavity 121 has the chamber 124 and 125 that demarcation strip 123 is separated into.In addition, cavity of resorption 119 comprises upstream cavity 126 and downstream cavity 127.The inner space of downstream cavity 127 has the chamber 129 and 130 that demarcation strip 128 is separated into.The chamber 125 of upstream cavity 121 and the chamber of downstream cavity 127 130 are communicated with by passage 131.
At heat exchanger 117, the heat exchange medium that the fluid intake part 132 by being arranged on downstream cavity 127 chambers 129 is introduced flows through heat exchanger 117, as shown in figure 10, discharges from the fluid issuing part 133 of the chamber 124 that is arranged on upstream cavity 121.At heat exchanger 117, passage 131 is outstanding in the direction of stacked pipeline group 120.Fluid intake part 132 and fluid issuing part 133 are arranged on the side surface of heat exchanger 117, so the installing space of heat exchanger 117 has reduced.In addition, heat exchanger 117 has not the structure overlapping with a part of pipeline group 120, because the inertia force of solution-air cold-producing medium is easy to introduce vapor phase refrigerant, another part of pipeline group 120 is easy to along air-flow direction A " introduces liquid phase refrigerant.Therefore, the air themperature by heat exchanger 117 is balanced in whole pipeline group 120.
But, also exist to realize the further requirement of thin type, promptly reduce the depth dimensions (be reduced to less than or equal 40 millimeters) of heat exchanger as depth dimensions.
Yet, directly reduce if all have the depth dimensions of the heat exchanger 117 that heat exchanger 100 that Fig. 9 of four refrigerant flowpath shows or Figure 10 show, can have problems.If the depth dimensions of heat exchanger 100 or heat exchanger 117 reduces, the sectional area of the flow path of each pipeline also reduces, and then the pressure loss of cold-producing medium increases.The result is, the internal circulating load of cold-producing medium can reduce, and the temperature of perhaps introducing the cold-producing medium of heat exchanger 100 or heat exchanger 117 can increase and the efficient of heat exchanger reduces.On the other hand, if an interblock dividing plate is taken out from heat exchanger 100 or heat exchanger 117 and reduce refrigerant flowpath and reduce the pressure loss, the air themperature by heat exchanger 100 or heat exchanger 117 can be balanced.For example, with reference to figure 9, if space bar 109 takes out, the cold-producing medium that flows out from passage 112 should flow into all pipelines with being equal to.But, the coolant channel of chamber width prolongs too, because the difference between inertia (incrutial) power of the inertia force of vapor phase refrigerant and liquid phase refrigerant, it is very difficult that cold-producing medium flows into all pipelines.
In addition, the heat exchanger 117 that the heat exchanger 100 that Fig. 9 shows or Figure 10 show comprises along refrigerant flowpath having the long-pending path of small cross sections, and cold-producing medium concentrates in the path.Therefore, the pressure loss may rise.In addition, path is difficult to bring into play heat exchange action.In addition, the path 131 of the heat exchanger 117 of Figure 10 demonstration protrudes in width.Therefore, come to introduce or discharge from width the heat exchanger of heat exchange medium for the chamber, side is set, the size of heat exchanger width increases.
Therefore, produced having overcome these and other the needs of the combined type multi-flow heat exchanger that is used for air conditioner for vehicles of shortcoming of correlation technique.Technological progress of the present invention makes the combined type multi-flow heat exchanger control the pressure loss of cold-producing medium, makes the air themperature equilibrium by heat exchanger, and it is slim to have realized that size minimizing, particularly heat exchanger become.
