Detailed description of the invention
Fig. 1 to Fig. 2 shows the embodiment of a kind of heat exchanger that the utility model provides.
Described heat exchanger is used for and air exchange heat, is one of the core component of air-conditioning system.In order to improve heat exchange efficiency, described heat exchanger is usually arranged at the outdoor air that waits and flows good position.Be arranged at outdoor heat exchanger and be called outdoor heat exchanger, such as, air-conditioner host carries out heat better in order to abundant and air, is usually arranged on the top of building or the exterior wall of building.The utility model take outdoor heat exchanger as operation principle and the beneficial effect that embody rule scene sets forth this technical scheme, but the installation site of the operation principle of heat exchanger that provides of the utility model and beneficial effect and this heat exchanger has nothing to do.
Please refer to Fig. 1, the heat exchanging piece 2 that described heat exchanger comprises housing 3 and is arranged in this housing 3.Described housing 3 exchanges warmware 2 and other parts play supporting protection effect, and provides mounting structure and installation site for this heat exchanging piece 2 and other parts.This housing 3 is generally the square case structure that metal material is made.Described housing 3 includes the ventilating opening exchanged with contacting external air.As preferred embodiment, in order to accelerate air flowing, improve heat exchange efficiency, described heat exchanger is being provided with relative to the housing place of side the blower fan 4 acting on described heat exchanging piece 2 with described ventilating opening.This blower fan 4 is for aspirating the air at described heat exchanging piece 2 place.Described housing 3 comprises the fan installation plate 31 for install described blower fan 4 relative with described ventilating opening.
Particularly, this housing 3 comprises base plate 34, top board 32, left plate 35 and right plate 33, and fan installation plate 31, and above-mentioned five plates are fixedly connected into cuboid case structure.Described vent position place, relative left plate 35 is concordant with the edge of right plate 33.
The heat exchanging piece 2 of described heat exchanger is the device being actually used in heat exchange in this heat exchanger, and common heat exchanging piece 2 structure type has copper tube and fin heat exchanging piece and Thermal Performance of Micro Channels part.Thermal Performance of Micro Channels part has for copper tube and fin heat exchanging piece that volume is little, lightweight, heat exchange efficiency advantages of higher, therefore obtains develop rapidly and extensive use.In the present embodiment, namely described heat exchanger selects Thermal Performance of Micro Channels part.
In order to improve heat exchange efficiency, increase heat exchange area and save inner space, described heat exchanging piece 2 is generally platy structure, U-shaped or L-type platy structure, comprises just to the first plate of described ventilating opening, and is fixed on described left plate 35 and described right plate 33.The action direction of described blower fan 4 is perpendicular to the first plate in this heat exchanging piece 2.
Invariably cannot there are dust and other foreign material in air.Be positioned over outdoor heat exchanger, because heat exchanging piece 2 air-side blockage reduces, cause air-flow uneven, in addition longitudinal Wave-shaped structural of microchannel fin, and fin clearance is little and the degree of depth is large, dust and other foreign material easily accumulate on fin, thus cause dirty stifled, have a strong impact on air intake efficiency and the heat exchange efficiency of described heat exchanging piece 2.
In order to solve the problem, described housing 3 is connected with detachable screen pack 1 at described ventilating opening.Removably connecting of described detachable screen pack 1 and described housing 3 realizes by such as under type.
As shown in Figure 1, described housing 3 is provided with the coupling assembling described detachable screen pack 1 being connected to described housing 3 in the position of described ventilating opening, described coupling assembling is included in the screen pack supporting seat 6 that described base plate 34 is arranged, at the screen pack position limiting structure 5 that described left plate 35 and described right plate 33 are arranged, and the screen pack that is fixed on this top board 32 of rotation arranged on described top board 32 fixes plectrum 7, fix plectrum 7 by rotating described screen pack described detachable screen pack 1 limited or lifts restrictions in described housing 3.Particularly, described screen pack position limiting structure 5 is for being arranged at the bulge-structure on described left plate 35 and described right plate 33, and this bulge-structure contacts with described detachable screen pack 1 marginal texture, limits the position of this detachable screen pack 1.Described screen pack fix plectrum 7 towards during this detachable screen pack 1 and described housing 3 coordinate can limit described detachable screen pack 1.Design like this, structure is simple, facilitates the dismounting of described detachable screen pack 1, and without the need to other special dismantling devices, easily realizes.
The filtration zone of described detachable screen pack 1 is greater than the area of heat-transfer surface relative with described ventilating opening in described heat exchanging piece 2.This detachable screen pack 1 extended surface keeps setpoint distance smooth and easy to ventilate with the heat-transfer surface relative with ventilating opening of described heat exchanging piece 2, and the described housing 3 at edge corresponding with described ventilating opening, at least one section of edge keeps setpoint distance.Even if design like this made to cross detachable strainer 1 large area dirty stifled time, still by reserved gap air intake, the operation ensureing unit can be continued, makes maintenance period more flexible.
Described detachable screen pack 1 comprises the frame that this individual layer nylon wire is fixed in individual layer nylon wire and tensioning.Described frame adopts metal to make usually.
As alternative embodiment, described detachable screen pack 1 also realizes by the following two kinds mode with removably connecting of described housing 3:
The first, described housing 3 is provided with the groove of this detachable screen pack 1 of engaging in position, described ventilating opening continuous print three limits, is provided with the fixture of fixing detachable screen pack 1 in another side position; The second, this detachable screen pack 1 is threaded connection device with described housing 3 and realizes.
Also can be provided with other parts in described housing 3, owing to haveing nothing to do with the technical program, therefore not describe.
The heat exchanger that the utility model provides, when there is the dirty problem such as stifled, only need clean or change detachable screen pack 1, solves prior art and need dismantle or flushing heat exchanging device and the complicated operation that causes and the high problem of cost.And owing to extending the dirty stifled time of heat exchanging piece 2 after program enforcement, the drafting efficiency of heat exchanging piece 2 and the decrease speed of heat exchange efficiency are slowed down, thus maintenance period is increased, reduce the cost safeguarded.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of extending out or variation be still among the protection domain that the utility model creates.
