Embodiment
Referring to Fig. 1 and Fig. 2, a kind of high-efficiency evaporator, described evaporimeter is syllogic, first paragraph evaporimeter 1 forms bending with second segment evaporimeter 2, comprise that U-shaped pipe, two refrigerant inlet pipe 1-3,2-3 and two refrigerants go out to manage 2-4,2-5, first paragraph evaporimeter 1 and second segment evaporimeter 2 are the U-shaped pipe of interior row and the double-row type structure that effluxes U-shaped pipe, the 3rd section evaporimeter 3 is the single row type structure, the import of two refrigerant inlet pipe 1-3,2-3 respectively with first paragraph evaporimeter 2 are connected with the second segment evaporimeter bending connection part U-shaped pipe be connected.
With regard to concrete technical scheme, the import of refrigerant inlet pipe a1-3 is connected with the U-shaped pipe 1-1 that effluxes of first paragraph evaporimeter 1 bending connection part; The import of refrigerant inlet pipe b2-3 is connected with the U-shaped pipe 2-1 that effluxes of second segment evaporimeter 2 bending connection parts.Referring to Fig. 2.
Evaporimeter of the present utility model has 15 U-shaped pipes, and first paragraph evaporimeter 1 is 6 U-shaped pipes, and second segment evaporimeter 2 is 7 U-shaped pipes, and the 3rd section evaporimeter 3 is 2 U-shaped pipes.
The outlet that refrigerant goes out to manage a2-4 is connected with the U-shaped pipe 2-2 of the interior row of second segment evaporimeter 2, and the position is upper; The outlet that another refrigerant goes out to manage b2-5 is connected with the U-shaped pipe 2-2 of the interior row of second segment evaporimeter 2, and the position is lower.Two refrigerants go out pipe and are oppositely arranged, and at a distance of a U-shaped pipe distance.
The refrigerant flow path of evaporimeter is two-way, one road refrigerant flow path, the 8 U-shaped pipes of flowing through, another road refrigerant flow path 7 U-shaped pipes of flowing through.
Referring to Fig. 2, the flow through flow line of 7 U-shaped pipes of refrigerant flow path is: refrigerant is entered into the U-shaped pipe 2-1 that effluxes of second segment evaporimeter 2 bending connection parts by refrigerant inlet pipe b2-3, then flow through to the U-shaped pipe 2-2 of the interior row of adjacent second segment evaporimeter, flow through again to the U-shaped pipe 2-1 of effluxing of adjacent second segment evaporimeter, from the U-shaped pipe 2-1 of effluxing of this second segment evaporimeter flow through downwards stride the pipe a4-1 enter into the 3rd section single U-shaped pipe 3-1 of 3 evaporimeters lower end, upwards flow through the single U-shaped pipe 3-1 of 2 the 3rd section evaporimeters along the 3rd section single U-shaped pipe 3-1 of evaporimeter, flow through again to the U-shaped pipe 2-1 of effluxing of second segment evaporimeter, and flow through from bottom to top the U-shaped pipe 2-1 of effluxing of second segment evaporimeter, flow through again to the U-shaped pipe 2-2 of the interior row of second segment evaporimeter, flow out from go out to manage a2-4 at upper refrigerant at last.
Can find out following characteristics from above-mentioned 7 U-shaped pipe flow processs: after 1, refrigerant flows through first 2 U-shaped pipes of second segment evaporimeter, with regard to three sections evaporimeters 3 of turn of tidal stream to the, after having flowed the 3rd section evaporimeter 3, go back to again second segment evaporimeter 3, so that the 3rd section evaporimeter good effect of heat exchange, the 3rd section evaporimeter wind speed is very fast in addition like this, and heat exchange is better, thereby make the heat exchange of second and third section evaporimeter more balanced, the phenomenon of having subdued weighing apparatus uneven in temperature.2, in these 7 U-shaped pipe flow processs, effluxing is 5 U-shaped pipes, because the heat exchange efficiency that effluxes will be higher than interior row, thereby has improved heat exchange efficiency and Energy Efficiency Ratio, and through experimental test, Energy Efficiency Ratio has improved about 2%.
Referring to Fig. 2, the flow through flow line of 8 U-shaped pipes of refrigerant flow path is: the refrigerant flow path route of first paragraph evaporimeter 1 is the U font, refrigerant is entered into the U-shaped pipe 1-1 that effluxes of first paragraph evaporimeter bending connection part by refrigerant inlet pipe a1-3, along U font refrigerant flow path route, by the U-shaped pipe 1-2 of interior row that effluxes U-shaped pipe 1-1 and forward to afterwards from the top down the lower end, flow to the U-shaped pipe 1-2 of interior row upper end by the U-shaped pipe 1-2 of interior row lower end again, through striding the pipe b4-2 U-shaped pipe 2-2 of row to the lower end of second segment evaporimeter that flows through, flow from bottom to top along the U-shaped pipe 2-2 of row in the second segment evaporimeter, at last under refrigerant go out to manage b2-5 and flow out.
When 7 and 8 U-shaped pipe process ends, all at the close position of the interior row of second segment evaporimeter 2, the refrigerant state of two-way is about the same like this, cold and hot equilibrium.
Have knockout in the evaporimeter, described knockout is the flat threeway of folder.
Evaporimeter of the present utility model has improved exchange capability of heat and complete machine Energy Efficiency Ratio, has solved the solidifying water of this type heat exchanger and has blown water problem.
As shown in Figure 1 and Figure 2, U-shaped pipe quantity is 15, two to advance two folding syllogic evaporimeter flow charts of scene 2, first paragraph wherein, and second segment is double, the 3rd section is single.One tunnel U-shaped pipe number is 8, is called and sets out on a journey, and the U-shaped pipe number in another road is 7, is called lower road.Import and export the flat threeway of folder that knockout all adopts red copper, the novel flow process of this high-performance heat exchanger is mainly reflected in: flat threeway separatory design is arranged, pressed from both sides to the effluent stream journey reasonably, and reasonably inside and outside row pipeline is arranged.
Consider that from design angle high-efficiency evaporator of the present utility model is the exchange capability of heat that improves heat exchanger from improving coefficient of heat transfer aspect.The first, consider that two-way pipe number does not wait, the pipe number of setting out on a journey is more, will inevitably be overheated.According to the theory of fin-tube type heat exchanger, the heat exchange efficiency that effluxes will be higher than interior row, so this flow process effluxed 7 tunnel as much as possible being arranged in of U-shaped pipe in when design, has guaranteed that shunting evenly; Second, two refrigerant imports of evaporimeter are arranged on first paragraph and second segment connection place, when having guaranteed that like this wind is introduced the air channel from the evaporimeter top, wind-warm syndrome by first paragraph evaporimeter and second segment evaporimeter is even, be difficult for ponding in the air channel, condensate water is dripped in the air channel or is blown out by fan when preventing that heat exchanger from moving under high humility weather; The 3rd, the 3rd section in evaporimeter is designed to single, wind speed is very fast, and heat exchange is better, so namely cause the 3rd section by jumper pipe after the refrigerant on lower road enters heat exchanger, prevents that refrigerant is overheated serious when flowing to the 3rd section, causes air-conditioner to blow water.
By the design of these three aspects, so that the separatory of evaporimeter has reached desirable effect, blow water and solidifying water problems when reasonably line arrangement has also avoided this type evaporimeter to work under high humidity.Use the flat threeway separatory of folder, guaranteed the uniformity of shunting; Two advance the flow arrangement of scene 2, have reduced the refrigerant crushing of evaporimeter.
Evaporimeter of the present utility model can be configured in the air conditioner room unit.
The above only is preferred embodiment of the present utility model, is not to be the restriction of the utility model being made other form, and any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.All technical solutions of the utility model contents that do not break away to any simple modification, equivalent variations and remodeling that above embodiment does, still belong to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
