The refrigerant channel of the technical scheme adopts the micro-channel flat tube, so that the product thickness is thinner, and the space is saved; the contact area of the micro-channel flat tube and the aluminum plate is large, the flat tube can be firmly bonded with the aluminum plate, glue is not easy to be separated, and the heat exchange efficiency is high.
Description
Technical Field
The utility model relates to a plate-type evaporator, which is particularly suitable for being used on household electrical appliances refrigerators and freezer cabinets.
Background
At present, plate evaporators of household appliances such as refrigerators and freezers are arranged in cavities of the refrigerators and freezers, and refrigerants are evaporated in the evaporators to absorb heat, so that the purpose of reducing the temperature in the cavities of the refrigerators and freezers is achieved.
The plate evaporator is formed by coiling a round aluminum pipe into a snake shape and then flattening the coil to form a refrigerant channel, and then bonding the coil on a flat aluminum plate through an aluminum pipe. A layer of vulcanized film is arranged between the aluminum pipe and the aluminum plate to bond the aluminum pipe and the aluminum plate together.
In the production process, the section of the aluminum pipe is flattened from a circular shape so as to increase the contact surface between the aluminum pipe and the aluminum plate and improve the heat exchange area. The contact part between the flattened plane part of the aluminum pipe and the aluminum plate is not large, the heat exchange amount is small, and simultaneously, glue is easy to split, thus causing waste products.
In addition, the degree of flattening of the outer circle aluminum pipe is influenced by factors such as the hardness of the aluminum pipe, parameters of a punch press, the shape of an aluminum pipe bent pipe and the like, so that the volume inside the aluminum pipe is unstable, the filling amount of a refrigerant is uncertain, and the performance of a refrigerator and a freezer is influenced.
Disclosure of Invention
The utility model aims to provide a microchannel plate evaporator with large heat exchange area, high heat exchange efficiency and stable inner volume.
The utility model discloses a task is accomplished like this, its characterized in that: the micro-channel plate type evaporator comprises flat aluminum tubes, flat surfaces of flat aluminum tube bodies are bonded with aluminum plates, two preset aluminum round tubes are arranged to be separated by a distance, one end of each aluminum flat tube is wound on one preset aluminum round tube and then overturns 360 degrees to the inclined lower side of the other aluminum round tube to bend back and forth, an inlet tube is welded with the head ends of the aluminum flat tubes, and an outlet tube is welded with the tail ends of the aluminum flat tubes and then is bonded with the aluminum plates through heat conducting glue films to form the micro-channel plate type. The distance between the two preset aluminum round pipes is based on the width of the aluminum plate. The quantity of the aluminum flat tubes bent back and forth is based on the condition that the flat surfaces of the aluminum flat tubes are fully covered with the aluminum plate surface. The aluminum flat tube is an existing aluminum flat tube with reinforcing ribs.
The utility model has the advantages that the refrigerant channel of the technical proposal adopts the micro-channel flat tube, the product thickness is thinner, and the space is saved; the contact area of the micro-channel flat tube and the aluminum plate is large, the flat tube can be firmly bonded with the aluminum plate, glue is not easy to be separated, and the heat exchange efficiency is high.

FIG. 1 is a perspective view of a microchannel plate evaporator; FIG. 2 is a schematic view of a microchannel plate evaporator; FIG. 3 is a top view of FIG. 2; FIG. 4 is a schematic view of a pre-arranged aluminum round tube; fig. 5 is a schematic structural diagram of a section of an aluminum flat tube.
Description of the drawings: 1. aluminum plate, 2, flat aluminum pipe, 3, outlet pipe, 4, import pipe, 5, preset aluminum circular tube.
Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
The micro-channel plate type evaporator comprises an aluminum flat tube 2, a flat surface of an aluminum flat tube body is bonded with an aluminum plate, and the defects that in the prior art, the flat surface part of the aluminum tube after being flattened is contacted with the aluminum plate, the contact part of the flat surface part and the aluminum plate is not large, and the heat exchange quantity is small are overcome.
In order to enable the flat surface of the aluminum flat tube body to be covered with the aluminum plates, the technical scheme adopts two preset aluminum round tubes 5 to be separated by a distance, one end of each aluminum flat tube is wound on one preset aluminum round tube and then is turned 360 degrees to the oblique lower side of the other aluminum round tube to be bent back and forth, and the fact that the flat surface of each aluminum flat tube is covered with the aluminum plate is taken as the criterion.
After the flat aluminum pipe body is formed, an aluminum round pipe is preset to be drawn out from two ends, an inlet pipe 4 is welded with the head end of the flat aluminum pipe, and an outlet pipe 3 is welded with the tail end of the flat aluminum pipe and then is bonded with an aluminum plate 1 through a heat conducting glue film to form a micro-channel plate type evaporator.
The distance between the two preset aluminum round pipes is based on the width of the aluminum plate.
The aluminum flat tube is an existing aluminum flat tube with reinforcing ribs.
In order to avoid the aluminum flat tube to appear dying to roll over and lead to the refrigerant can't flow in the course of working, preset aluminum circular tube 5 in the inner circular arc that flat tube upset was wound, let aluminum circular tube form the location support effect when 360 upsets of circular arc around aluminum flat tube.
As shown in fig. 2, the refrigerant enters from the inlet pipe and flows into the plurality of holes of the aluminum flat tube, as shown in the schematic cross-sectional structure of the aluminum flat tube in fig. 5. The refrigerant is from liquid phase transition to the gaseous state in the flat aluminium pipe, absorbs the heat, because the refrigerant is shunted in the flat aluminium pipe's a plurality of passageways to following the flat aluminium pipe positive and negative upset, making the refrigerant heat transfer abundant, and conduct aluminum plate through the flat aluminium pipe outer wall, aluminum plate absorbs the heat in refrigerator, refrigerator-freezer cavity, reduces refrigerator, refrigerator-freezer cavity internal temperature, and the last refrigerant is flowed by the outlet pipe.
In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected, and may communicate between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
