Description
Technical field
The present invention relates to a kind of plate-type evaporators, especially suitable for using on refrigerator appliance, refrigerator-freezer.
Background technique
Currently, the plate-type evaporator of refrigerator appliance, refrigerator-freezer, be refrigerator, refrigerator-freezer cavity in, refrigerant is in evaporator
Face evaporation absorbs heat, and achievees the purpose that reduce refrigerator, refrigerator-freezer cavity inner temperature.
Existing plate-type evaporator in industry is to form the channel of refrigerant, then at flattening after serpentine by circle aluminum pipe disk
It is bonded on a smooth aluminium sheet by aluminum pipe, forms plate-type evaporator.Have between aluminum pipe and aluminium sheet one layer of sulfide film by aluminum pipe with
Aluminium sheet bonds together.
In process of production, aluminum pipe section is flattened by circle, is the contact surface in order to increase aluminum pipe and aluminium sheet, is changed with improving
Heat area.Aluminum pipe flatten after planar section and aluminium sheet contact portion and little, heat exchange amount is small while being also easy to come unglued, and causes
Waste product.
In addition justify the degree that aluminum pipe flattens, by factors shadows such as the hardness of aluminum pipe, the parameter of punching machine, the shapes of aluminum pipe bend pipe
It rings, causes the volume inside aluminum pipe unstable, keep refrigerant charge uncertain, influence the performance of refrigerator, refrigerator-freezer.
Summary of the invention
The task of the present invention is proposing that a kind of heat exchange area is big, a kind of heat exchange efficiency is high, internal volume is stable microchannel plate
Formula evaporator.
The task of the present invention is what is completed in this way, it is characterised in that: microchannel plate-type evaporator includes aluminium flat conduit, the aluminium
The flat horizontal surface of flat tube ontology is Nian Jie with aluminium sheet；Cause refrigerant that can not flow in order to avoid dead folding occurs in aluminium flat conduit in process
It is dynamic, flat tube overturning around Inner arc inside preset aluminium round tube, two preset aluminium round tubes are spaced out, by aluminium flat conduit one end
It is wound on a preset aluminium round tube and overturns 360 ° of zigzags to another aluminium round tube obliquely downward again；After aluminium flat conduit sheet is body formed,
Preset aluminium round tube is extracted out from both ends, inlet tube and aluminium flat conduit head end are welded, outlet passes through again with the welding of aluminium flat conduit end
Conductive adhesive film is Nian Jie with aluminium sheet, constitutes microchannel plate-type evaporator.The distance between described two preset aluminium round tubes are with aluminium sheet
Subject to width.The quantity of the aluminium flat conduit zigzag is subject to the flat horizontal surface of aluminium flat conduit and is covered with aluminium sheet plate face.The aluminium flat conduit
Using the existing aluminium flat conduit with reinforcing rib.
The present invention has the following effects that, the coolant channel of the technical program be using micro-channel flat, product thickness compared with
It is thin, save space；Micro-channel flat and aluminium sheet contact area are big, and flat tube can be made Nian Jie with aluminium sheet securely, be not easy to come unglued, and change
The thermal efficiency is high.
Detailed description of the invention
Fig. 1 is microchannel plate-type evaporator perspective view；Fig. 2 is the board-like evaporation structure schematic diagram in microchannel；Fig. 3 is Fig. 2
Top view；Fig. 4 is preset aluminium round tube schematic diagram；Fig. 5 is aluminium flat conduit cross section structure schematic diagram.
Drawing explanation: 1, aluminium sheet, 2, aluminium flat conduit, 3, outlet, 4, inlet tube, 5, preset aluminium round tube.
Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
Specific embodiment as shown in Figure 1, microchannel plate-type evaporator includes aluminium flat conduit 2, the aluminium flat conduit ontology it is flat
Face is Nian Jie with aluminium sheet, and the customer service prior art is that the planar section after flattening aluminum pipe is contacted with aluminium sheet, and the two contact portion is simultaneously
Less, and the small defect of heat exchange amount.
In order to make the flat horizontal surface on aluminium flat conduit ontology be covered with aluminium sheet, the technical program is pulled open using two preset aluminium round tubes 5
2 one end of aluminium flat conduit is wound on a preset aluminium round tube and overturns 360 ° of zigzags to another aluminium round tube obliquely downward again by distance,
Folding to is covered with the flat horizontal surface of aluminium flat conduit subject to aluminium sheet plate face.
After aluminium flat conduit sheet is body formed, preset aluminium round tube is extracted out from both ends, inlet tube 4 and aluminium flat conduit head end are welded, out
Mouth pipe 3 welds again, composition microchannel plate-type evaporator Nian Jie with aluminium sheet 1 by conductive adhesive film with aluminium flat conduit end.
The distance between described two preset aluminium round tubes are to be subject to aluminium sheet width.
The aluminium flat conduit is using the existing aluminium flat conduit with reinforcing rib.
Cause refrigerant that can not flow in order to avoid dead folding occurs in aluminium flat conduit in process, in flat tube overturning in
Preset aluminium round tube 5 inside circular arc forms positioning support effect when allowing aluminium round tube to aluminium flat conduit around 360 ° of overturnings of circular arc.
If Fig. 2 shows, refrigerant is entered by inlet tube, flows to the porous interior of aluminium flat conduit, as Fig. 5 aluminium flat conduit cross section structure is illustrated
Figure.Refrigerant is changed into gaseous state from liquid in aluminium flat conduit, absorbs heat, since refrigerant is divided to the multiple logical of aluminium flat conduit
In road, and the and then positive and negative overturning of aluminium flat conduit, keep refrigerant heat exchanger abundant, and be transmitted to aluminium sheet, aluminium sheet by aluminium flat conduit outer wall
In refrigerator, refrigerator-freezer chamber body absorption heat, refrigerator, refrigerator-freezer cavity inner temperature are reduced, last refrigerant is flowed out by outlet.
In the present invention unless specifically defined or limited otherwise, the arts such as term " installation ", " connected ", " connection ", " fixation "
Language shall be understood in a broad sense, for example, it may be fixedly connected, may be a detachable connection or integrally connected, can be two members
Connection inside part.For those skilled in the art, above-mentioned term can be understood of the invention as the case may be
Concrete meaning.
