Abstract
A heat exchanger of a household refrigerator comprises a pipeline (3) through which a heat exchange medium flows, and an open-pored metal foam (1) molded onto the pipeline (3).
Description
Technical field
The present invention relates to a kind of chilling unit, relate to a kind of family expenses chilling unit especially, this chilling unit comprises heat exchanger, and it comprises the pipeline of stream through the heat transfer medium material.This heat exchanger is used as condenser in chilling unit, to discharge heat in the zone towards periphery from compression refrigerant; Or, absorb heat from the refrigerating chamber in the chilling unit by the refrigerant that expands as evaporimeter.Wherein, the known spool structure of condenser extensive use particularly, the pipe fitting that is about to transport refrigerant is bent into the circuitous ring road that is positioned at a plane, and makes the structure of loop become stable and increase heat exchange surface across crossing wire rod that loop welds.
Background technology
But it is labour-intensive producing such condenser, because these wire rods need to be welded on the pipeline separately length by length.
A kind of heat exchanger with pipeline of the foaming metal that runs through perforate has been described among DE 101 23 456A1.Described pipeline is cast in the foaming metal.Owing to main cavity in making the process of foaming metal is necessary for that pipeline is prepared or must makes in one step of back, and the casting pipeline needs complicated mould, thereby it is also very complicated to make such heat exchanger.If heat transfer fluid must flow through a plurality of areas under control section of series connection, these area under control sections must be connected to each other together through complicated step in the foaming metal main body outside so.
Summary of the invention
The purpose of this invention is to provide a kind of chilling unit, the heat exchanger of described chilling unit has high heat exchanger effectiveness and low manufacturing cost.
This purpose is to realize by following content: on the pipeline in having the chilling unit of heat exchanger, and the foaming metal of molded perforate, described heat exchanger comprises the pipeline of process that heat transmission medium flows.
Foaming metal is preferably formed plate shaped main body, and wherein pipeline passes through this plate shaped main body with the form of circuitous or bending.
For heat exchanger is installed on the chilling unit, described pipeline preferably includes the section of not imbedding between two sections in being embedded in main body, wherein if necessary, the section fastener of not imbedding is attachable to described two and imbeds section, and does not damage the structure of foaming metal.
Preferably, described pipeline comprise respectively many of connecting by the curved section of not imbedding straight imbed section.
In order to improve before heat exchanger is mounted to chilling unit in advance its processing of carrying out or operation, usefully pipeline is provided with in body interior relative to one another near two terminal loops.
Described heat exchanger is suitable for the condenser as chilling unit.
Preferably foaming metal can be an aluminium alloy.
Pipeline is preferably made by the metal that fusing point is higher than aluminium alloy.Because the metal of making pipeline is efficient heat transfer expediently, therefore can consider to use copper especially.
Especially, heat exchanger is to make by the foaming metal of casting around pipeline.Optionally, pipeline and the precast body material that is used for foaming metal might be placed on mould, and the precast body material is foamed in mould.
Description of drawings
From a description will be given of an embodiment in accordance with the present invention with reference to the accompanying drawings, further aspect of the present invention, advantage will become apparent:
Fig. 1 is the perspective view of heat exchanger, in order to show basic principle of the present invention; And
Fig. 2 is the rearview that has according to the chilling unit of heat exchanger of the present invention, and wherein heat exchanger is as condenser.
The specific embodiment
Comprise the flat rectangle block of particularly being made by aluminium alloy by foaming metal 1 with the heat exchanger shown in the perspective view among Fig. 1, wherein many area under control sections 2 are passed described block 1 abreast.Shown mutual disjunct area under control section 2 can in series interconnect in block 1 outside and be integral; Also many all area under control sections 2 can be connected with the import export distributor in the mode that is arranged in parallel.
The block 1 that the foaming metal of described perforate is made has very large specific area or surface coefficient, and can closely be connected with the metal of area under control section 2.Because the air flow resistance of bearing is less, thus area under control section 2 and around and the air of the block 1 of flowing through between can carry out heat exchange efficiently.
Fig. 2 illustrates and is supporting the vertical view of the back of the chilling unit of heat exchanger as shown in Figure 1, and wherein this heat exchanger is as condenser.The edge length that forms tabular block 1 this condenser, that made by foaming metal is a little less than the length of described chilling unit rear wall, and wherein condenser is suspended on the rear wall of chilling unit.Heat-exchange tube 3 passes foaming metal block 1 from compressor 4 with circuitous or tortuous form continuously with the form of monomer spare, and arrives the evaporimeter (not expressing among the figure) of chilling unit inside through the choke point.
Heat-exchange tube 3 extends in block 1 inner main form with the many rectilinear tubes sections 5 that are parallel to each other.The route of schematically representing this area under control section 5 in the rearview 2 with solid line; In fact, area under control section 5 is fully imbedded in the block 1, can not see from the outside.Two adjacent area under control sections 5 are connected to each other by the pipe bend 6 that stretches out block 1 outside respectively.The anchor clamps 7 (each such pipe bend 6 in its clamping) that are secured on the rear wall of chilling unit are fastened to the chilling unit housing with condenser.
In block 1 zone below, have two pairs of area under control sections 8,9, this area under control section 8,9 does not extend to opposite side from a side of block 1, but interconnects in block inside by pipe bend 10 and 11 respectively.Be used as the middle fastener of long pipe fittings 12 substantially by area under control section 8 and pipe bend 10 formed loops, bending or kinking take place when preventing that long pipe fittings 12 from operating before condenser is mounted to chilling unit in advance, and wherein this long pipe fittings 12 extends to the import 13 that is positioned at block 1 upper left corner from an end (it will be installed on the compressor 4 in the outside of block 1).
If necessary, be connected to the pressure export of compressor 4 by the pipe fitting 14 that will withdraw from or draw from block 1 lower right corner, and by (choke point) is connected to the evaporimeter of chilling unit inside through the choke point with long pipe fittings 12, refrigerant can be opposite with direction shown in Figure 2 by the through-flow direction of condenser.
