Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood at this with concrete condition
Concrete meaning in invention.
Below with reference to the accompanying drawings heat exchanger 1 according to an embodiment of the present invention is described.
As shown in Fig. 1-Figure 14, heat exchanger 1 according to an embodiment of the present invention includes multiple rows of sub- heat exchanger.Multiple rows of sub- heat exchanger
It arranges and is parallel to each other along the thickness direction of sub- heat exchanger, in other words, heat exchanger 1 is more to be arranged in by multiple sub- heat exchangers
Arrange heat exchanger.It is to be understood that ground is, the heat exchanger 1 of multiple rows of structure, wherein the unit for constituting each row is sub- heat exchanger,
Such as a heat exchanger bending, at two rows, it is two sub- heat exchangers that two two rows of units are constituted after two bendings.
Heat exchanger 1 has multiple coolant systems, and each coolant system is distributed at least two rows of sub- heat exchangers.Ability
The technical staff in domain it is to be understood that when heat exchanger 1 is applied to the heat-exchange system of more coolant loops, heat exchanger 1 it is multiple cold
Matchmaker's system constitutes a part of multiple coolant loops correspondingly.
Wherein, in the plane of thickness direction for being orthogonal to sub- heat exchanger, same coolant system is in any two rows of son heat exchange
Projection at least part of part on device is not overlapped.That is, same coolant system is on any two rows of sub- heat exchangers
Part is not exclusively overlapped on air-flow direction or is not overlapped completely, and the heat exchange area of any two coolant system can phase
It is same to can also be different.
For example, by taking double-refrigerant system as an example, portion of the same coolant system according to an embodiment of the present invention in two rows
Divide the heat exchanger 1 for not completing overlapping along air-flow direction, with part edge of the same coolant system in the prior art in two rows
The completely overlapped heat exchanger of air-flow direction is compared.
Wherein, air skims over heat exchanger surface, and from windward side to leeward side, the heat exchange efficiency of heat exchanger is gradually reduced, former
Because being from windward side to leeward side, the heat transfer temperature difference of air and refrigerant is gradually reduced (as shown in figure 13).Heat exchanger is negative in part
When lotus runs, it is assumed that only one coolant system is run in double-refrigerant system.
According to the heat exchange amount formula of heat exchanger: Q=KA Δ t=KA1Δt1+KA2Δt2.Wherein Q is heat exchange amount, K heat transfer system
Number, A heat exchange area, Δ t are heat transfer temperature difference, A1For windward side heat exchange area, A2For leeward side heat exchange area, Δ t1For windward side
Mean temperature difference, Δ t2For leeward side mean temperature difference.
It is assumed that the heat exchanger 1 of the embodiment of the present invention is as the structure of existing heat exchanger and air surface wind speed, i.e. K phase
Together.
The heat exchanger 1 of the embodiment of the present invention, heat exchange amount are as follows:
Q1=KA11Δt1+KA21Δt2Wherein A11>A21,Δt1>Δt2A11+A21=A；
Q2=KA12Δt1+KA22Δt2Wherein A12=A22,A21+A22=A；
Q1-Q2=K (A11-A12)Δt1-K(A22-A21)Δt2；
A11-A12=A22-A21；
Q as a result,1-Q2>0。
As it can be seen that the heat exchange amount of the heat exchanger 1 of the embodiment of the present invention is greater than the heat exchange amount of the heat exchanger of the prior art.
In addition, the variation of heat exchanger leaving air temp is as shown in figure 14, wherein straight line is the temperature curve of existing heat exchanger, saw
Tooth trace is the temperature curve of the heat exchanger 1 of the embodiment of the present invention.From the figure, it can be seen that the heat exchanger 1 of the embodiment of the present invention
Leaving air temp is more more uniform than the leaving air temp of existing heat exchanger.
Leaving air temp when due to sub-load be need height warm air mixed in air hose could at user uniformly
Reach, the temperature of such heat exchanger exit is more uneven, it is necessary to which longer pipe meets the mixing of height warm air, causes
Install not flexible, and installation cost is higher, and the heat exchanger 1 of the embodiment of the present invention is since leaving air temp is more uniform, peace
Fill that more flexible, installation cost is lower.
Therefore, heat exchanger 1 according to an embodiment of the present invention is suitable for more coolant loops, heat exchange area when operation at part load
Utilization rate is higher, so that heat exchange efficiency is higher, and leaving air temp is more uniform.
