Description
Technical field
The utility model relates to a kind of heat abstractor, particularly relates to the extraordinary special-shaped cambered surface heat exchanger in microchannel.
Background technology
Heat exchanger (being also called heat exchanger or heat-exchange apparatus) is used to make heat be delivered to cold fluid from hot fluid, with the device of the technological requirement of satisfied regulation, is convection heat transfer' heat-transfer by convection and heat conducting a kind of commercial Application.Heat exchanger is the common apparatus of chemical industry, oil, power, food and other many industrial department, occupies critical role aborning.In Chemical Manufacture, heat exchanger can be used as heater, cooler, condenser, evaporimeter and reboiler etc., applies more extensive.Heat exchanger kind is a lot, but substantially can divide three major types namely according to the principle of cold and hot fluid exchange heat and mode: dividing wall type, hybrid and heat accumulating type.In three class heat exchangers, dividing wall type heat exchanger application at most.The type of dividing wall type heat exchanger.
Microchannel, also referred to as micro-channel heat exchanger, is exactly passage equivalent diameter at the heat exchanger of 10-1000 μm.In the collector of this heat exchanger, dividing plate is set, heat exchanger runner is separated into several flow process, microchannel aluminium flat conduit (also known as " concurrent flow aluminium flat conduit ") is a kind of employing refining aluminium bar, by hot extrusion, sprays zinc preservative treatment through surface; thin-walled porous flat tubular material; be mainly used in the air-conditioning system of various cryogen; as the pipeline parts of carrying novel environment-friendly refrigerant, the novel environment friendly system of employing is the critical material of concurrent flow microchannel of new generation air-condition heat exchanger.
Traditional micro-channel heat exchanger is a kind of aluminium product, it is arranged side by side by a lot of bar parallel pipe, how to be assembled by fin between the parallel flat tube of microchannel, cause thermal conductivity not up to standard due to its fin and the suiting face deficiency of cooling tube, form a kind of circular pipe type radiating mode between fin and cold pipe, its radiating effect is not strong.In addition, when producing this kind of micro-channel heat exchanger, and due to spacing of fin little, all can form dead angle when carrying out surface treatment to this passage between tube wall and fin and produce bubble, inwall can not apply completely, if want by waving removal bubble, product bears the weight of water, cause product to produce distortion, adopt the method improving defatted concd and extend degreasing time, then can greatly increase production cost and environmental pollution.
Summary of the invention
For solve above-mentioned conventional microchannel heat exchanger fin and cooling tube suiting face not enough and cause that thermal conductivity is not up to standard, its surface treatment time can not apply completely and increase the problem such as production cost, environmental pollution, the utility model provides a kind of microchannel special type special-shaped cambered surface heat exchanger.
The technical scheme in the invention for solving the technical problem is: the extraordinary special-shaped cambered surface heat exchanger in a kind of microchannel, comprise flat tube, fin, side pipe, the quantity of described side pipe is two, described flat tube parallel side-by-side is fixed between side pipe, the shape of described flat tube is circular arc, described flat tube is provided with a plurality of louvre, fin is provided with between described two adjacent flat tubes, described fin is that V-shape assembles, and the upper end of one of them in two described side pipes is provided with a plurality of fixed head, another one is provided with inlet/outlet pipe.
Further, described fixed head is the square plate be welded on side pipe, and described fixed head offers circular fixation hole.
Further, the quantity of described fixed head is four.
Further, described fin is provided with reserved portion in that side near side pipe.
The beneficial effects of the utility model: global shape of the present utility model is arc, cambered surface is defined between multiple arc flat pipe, make this heat exchanger can be used in extraordinary occasion, by suiting face after improving fin and flat tube and assembling, compensate for the deficiency of its thermal conductivity, improve heat exchanger effectiveness, and this kind of heat exchanger is when producing, because it has cambered surface, when carrying out surface-treated and entering water and water outlet, all have certain to enter water with the contact for the treatment of fluid, angle of water, thus application, deal with and more lightly facilitate, reduce the production cost of heat exchanger, decrease the pollution to environment, substantially increase the service life of product, meet the requirement of user completely.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is close-up schematic view of the present utility model.
Detailed description of the invention
As depicted in figs. 1 and 2, the extraordinary special-shaped cambered surface heat exchanger in a kind of microchannel, comprise flat tube 2, fin 3, side pipe 1, the quantity of described side pipe 1 is two, described flat tube 2 parallel side-by-side is fixed between side pipe 1, the shape of described flat tube 2 is circular arc, described flat tube 2 is provided with a plurality of louvre 21, fin 3 is provided with between described two adjacent flat tubes 2, described fin 3 assembles in V-shape, and the upper end of one of them in two described side pipes 1 is provided with a plurality of fixed head 11, another one is provided with inlet/outlet pipe 12.
Further, described fixed head 11, for being welded on the square plate on side pipe, described fixed head 11 offers circular fixation hole 111.
Further, the quantity of described fixed head 11 is four.
Further, described fin 3 is provided with reserved portion 4 in that side near side pipe 1.
Global shape of the present utility model is arc, cambered surface is defined between multiple arc flat pipe 2, make this heat exchanger can be used in extraordinary occasion, by suiting face after improving fin 3 and flat tube 2 and assembling, compensate for the deficiency of its thermal conductivity, improve heat exchanger effectiveness, and this kind of heat exchanger is when producing, because it has cambered surface, when carrying out surface-treated and entering water and water outlet, all have certain to enter water with the contact for the treatment of fluid, angle of water, thus application, deal with and more lightly facilitate, reduce the production cost of heat exchanger, decrease the pollution to environment, substantially increase the service life of product, meet the requirement of user completely.
It is emphasized that, it is more than preferred embodiment of the present utility model, not any type of restriction is done in appearance to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong to the scope of technical solutions of the utility model.
