Abstract
An improved air-conditioning heat exchanger structure comprises a refrigerant containing device and a heat radiation device; the refrigerant containing device comprises a plurality of flat tubes and a refrigerant collecting tube, and the two are fixedly connected; and the heat radiation device is fins which are fixedly connected between the adjacent two flat tubes. The refrigerant collecting tube is a hollow structure, wherein, a plurality of partitions are arranged and used for dividing the interior into a plurality of parts; each flat tube is a porous hollow structure, and the two ends thereof are open; the fins are shaped like a curved wave; the flat tubes, the refrigerant collecting tube and the fins are aluminum structures; and an anti-corrosion coating is arranged on the surface of the heat exchanger. The aluminum pipes are flat, thereby being more beneficial to the contact of a refrigerant in the pipe with the surface in the pipe, increasing the air-facing surface at the surface outside the pipe and further improving the heat exchange performance of the heat exchanger; in addition, the improved air-conditioning heat exchanger structure can reduce the using amount of copper and reduce the production cost.
Description
Technical field
The invention belongs to air-conditioning technical field, relate to heat exchanger structure.
Background technology
To be aluminum fin 10 be nested in the structure of U type copper riffled tube 20 by the tube side formula that rises with the heat exchanger of existing domestic air conditioning, and as shown in Figure 1, this structure is used more extensive at present.
When operation of air conditioner, refrigerant flows in heat exchanger, during by with the contacting of U type copper riffled tube 20 inner surfaces, heat is sent to U type copper riffled tube 20 surfaces, be sent on the aluminum fin 10, aluminum fin 10 and surrounding air carry out heat exchange again, thereby have realized heat exchange.The shortcoming of its existence is:
1, the copper material proportion is bigger in this heat exchanger, has caused existing air-condition heat exchanger production cost very high;
2, the U type copper riffled tube in this air-condition heat exchanger is a cylindrical-shaped structure, this kind structure can be held a large amount of refrigerants, but refrigerant great majority in flowing can not fully contact with U type copper riffled tube inner surface, thereby have influenced heat exchange amount, and heat exchange effect is desirable not to the utmost;
3, U type copper riffled tube is a cylindrical-shaped structure, makes its surface have only half to be in the windward side, and half is in lee face, and heat exchange efficiency is lower.
Summary of the invention
Main purpose of the present invention is to provide a kind of novel heat exchanger, not only reduces the production low cost but also possess higher heat exchange efficiency.
For reaching above purpose, solution of the present invention is:
Improved air-conditioner heat exchanger structure comprises refrigerant storing apparatus, heat abstractor, and this refrigerant storing apparatus comprises some flat tubes and refrigerant collecting pipe, connects in fixedly connected mode between the two; This heat abstractor is a fin, is arranged between the adjacent two flat tubes in fixedly connected mode.
Further, be hollow-core construction in this refrigerant collecting pipe, some partitions wherein are set its inside is separated into several parts.
This flat tube can be the cellular hollow-core construction, and its two ends are structures of opening.
The refrigerant collecting pipe is inserted at these flat tube two ends, fixes with welding manner.
This fin is arranged between the adjacent two flat tubes with welding manner.
This fin is to have the shape that can increase with the outside air contact-making surface.
This fin is crooked wave-like, and its each peak adopts the mode of fixedlying connected to be connected and fixed with last row's flat tube; Its each minimum point adopts the mode of fixedlying connected to be connected and fixed with following row's flat tube.
This fixedly connected mode is welding.
This flat tube, refrigerant collecting pipe, fin are aluminum design.
Be provided with corrosion-inhibiting coating at heat exchanger surface.
Concurrent flow aluminum heat exchanger structure of the present invention is that aluminum fin is arranged on the flat type aluminum tube by fixedly connected mode, because aluminum tube is a flat, compare with cylindric U type pipe, refrigerant contacts with pipe internal surface in more helping managing, also increase the windward side of tube outer surface, thereby improved the heat exchange property of heat exchanger; Because of existing copper material price skyrockets, adopt this concurrent flow aluminum heat exchanger can reduce the copper material consumption in addition, reduce production costs.

The specific embodiment
The present invention is further illustrated below in conjunction with the accompanying drawing illustrated embodiment.
As shown in Figure 2, it is a kind of preferred embodiment of the present invention, aluminum flat tube 31,32 adopts the mode of fixedlying connected with aluminum refrigerant collecting pipe 1, for example weld together, welding wave mode aluminum fin 4 between two adjacent aluminum flat tube 31,32, some groups of such textural associations have constituted concurrent flow aluminum heat exchanger of the present invention.
In the aluminum refrigerant collecting pipe 1 is hollow-core construction, is the flow direction of control refrigerant, and inside need be separated into several parts, as in aluminum refrigerant collecting pipe 1 inside some partitions 6 being set its inside is separated into several parts;
Aluminum refrigerant collecting pipe 1 is inserted at the aluminum flat tube two ends, adopts fixedly connected mode, and for example welding is fixing, and aluminum flat tube 31,32 is the cellular hollow-core construction, and for guaranteeing the proper flow of refrigerant, the aluminum flat tube two ends should not blocked, and are the structures of opening;
Adopt fixedly connected mode to connect a wavy aluminum fin 4 between the per two adjacent aluminum flat tube 31,32, for example wavy aluminum fin 4 of welding between two adjacent aluminum flat tube 31,32.
This wavy aluminum fin 4 has the shape that can increase with the outside air contact-making surface, Wan Qu wave-like for example, and its each peak 41 (crest) and last row's aluminum flat tube 31 adopt the mode of fixedlying connected, and for example weld and fix; Its each minimum point 42 (trough) adopts the mode of fixedlying connected with following row's aluminum flat tube 32, and for example welding is fixing.Further, can corrosion-inhibiting coating be set in the increase of concurrent flow aluminum heat exchanger surface.
When operation of air conditioner, refrigerant is taken over 2 or second inflow of taking over 5 two interfaces from concurrent flow aluminum heat exchanger first, from another outflow, between the refrigerant flow periods by with the contacting of aluminum flat tube 31,32 inner surfaces, heat is sent to aluminum flat tube 31,32 surfaces, be sent to wavy aluminum fin 4 again, and wavy aluminum fin 4 and aluminum flat tube 31,32 outer surfaces and surrounding air carry out heat exchange, thereby realized heat exchange.
The above-mentioned description to embodiment is can understand and apply the invention for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiment, and needn't pass through performing creative labour being applied in the General Principle of this explanation among other embodiment.Therefore, the invention is not restricted to the embodiment here, those skilled in the art should be within protection scope of the present invention for improvement and modification that the present invention makes according to announcement of the present invention.
