Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figures 1 to 8, the utility model provides a kind of evaporimeter, comprising:
Interior liquid chamber pipe 200, described interior liquid chamber pipe 200 is arranged on the homonymy of bottom surface 120, and described interior liquid chamber pipe 200 comprises interior liquid chamber 210, and described bottom surface 120 is provided with the equal discharge orifice 121 that is communicated with outer liquid chamber 110 and interior liquid chamber 210.All discharge orifice 121, for refrigerant current-sharing, improves heat exchange amount.
Cancel partition and flow regulator pieces in prior art evaporimeter, reduced the production routines such as punching press and assembling, reduced the coolant leakage risk that welding brings; Employing is provided with the design of the equal discharge orifice 121 that is communicated with outer liquid chamber 110 and interior liquid chamber 210 at header 100, makes production and processing simple, and has better current-sharing effect, raising heat exchange efficiency.
Concrete, the cross section of described header 100 is " B " type.
Concrete, the both sides of described header 100 are respectively equipped with header weld part 130.More specifically, described interior liquid chamber pipe 200 two ends are respectively equipped with interior liquid chamber pipe weld part 220, and described interior liquid chamber pipe weld part 220 is arranged on header weld part 130.Described interior liquid chamber pipe weld part 220 is welded on header weld part 130.Each solder side coordinating with interior liquid chamber pipe 200 at header 100 is provided with two and above contact-making surface, has improved weld strength and welding yield.
Concrete, described equal discharge orifice 121 is circular hole or slotted eye or rectangular opening; The Circularhole diameter scope of described equal discharge orifice 121 is: 3mm ~ 8mm.Circular hole or slotted eye have better water conservancy diversion effect compared with rectangular opening.The size of the spacing between adjacent equal discharge orifice 121 and all discharge orifice 121, is subject to the length variations of header 100 and difference is nearer apart from refrigerant exit 520, all discharge orifice 121 is less, otherwise all discharge orifice 121 is larger, with this, adjust refrigerant flow rate, make in each harmonica-shaped tube 300 of its uniform inflow.
Concrete, bottom surface 120 is provided with header osculum 123.More specifically, described interior liquid chamber pipe 200 comprises the buckle 230 being arranged on header osculum 123, and described buckle 230 sizes are less than described header osculum 123.Header osculum 123 is that rectangle is circular or oval, according to the difference of evaporator operation condition, increase or reduce the quantity of header osculum 123, the refrigerating capacity of evaporimeter is higher, the condensed water producing is more, the setting of header osculum 123 is more intensive, if desired, can between adjacent two harmonica-shaped tubes 300, some header osculums 123 be set, make evaporimeter effectively draining at work.On header 100, be provided with the buckle 230 coordinating with interior liquid chamber pipe 200, interior liquid chamber pipe 200 and header 100 fastened fastening, improve soldering yield.
More specifically, described interior liquid chamber pipe 200 is provided with the interior liquid chamber pipe osculum 240 corresponding to header osculum 123.Described interior liquid chamber pipe osculum 240 is that rectangle is circular or oval, all matches with header osculum 123 in the shape of described interior liquid chamber pipe osculum 240 and position.Described buckle 230 is connected with interior liquid chamber pipe osculum 240, after described buckle 230 is fastened on header osculum 123, because the size of buckle 230 is less than header osculum 123, so header osculum 123 is remaining to be gone out a part and not to be blocked completely by buckle 230, header osculum 123 is corresponding with interior liquid chamber pipe osculum 240, and condensed water is discharged.And traditional parallel-flow evaporator is not owing to there is no header osculum 123 and corresponding interior liquid chamber pipe osculum 240, so drainage effect is not good, when air-conditioning long-play, it is not smooth that the condensed water on evaporimeter is got rid of, and reduces heat exchanger effectiveness.
Concrete, the cross section of described interior liquid chamber pipe 200 is " 3 " type.
Concrete, described evaporimeter comprises:
Harmonica-shaped tube 300,
Described interior liquid chamber pipe 200 is provided with mouth organ pore 250, and described harmonica-shaped tube 300 is arranged on mouth organ pore 250.Described harmonica-shaped tube 300 is welded on mouth organ pore 250.
More specifically, described bottom surface 120 is provided with harmonica-shaped tube limiting section 122, harmonica-shaped tube limiting section 122 described in described harmonica-shaped tube 300 butts.Traditional parallel-flow evaporator, when harmonica-shaped tube 300 is installed, need to first inserts plug and carry out spacingly, afterwards partition and flow regulator pieces could be installed, and assembling production process is long, has reduced production efficiency.On header 100, be provided with harmonica-shaped tube limiting section 122, can be directly spacing to harmonica-shaped tube 300 during assembling, while making harmonica-shaped tube 300 shift this position onto, cannot continue to push, reduced the number of linkage editor, improve efficiency of assembling.
More specifically, described evaporimeter comprises:
More specifically, the cross section of described fin 400 is U-shaped wavy 410 or rectangle wavy 420.Rectangular wavy 420 the fin in cross section is higher more than 10% than U-shaped wavy 410 heat exchange amount.
Concrete, described evaporimeter comprises:
Refrigerant import 510 and refrigerant exit 520, described refrigerant import 510 and refrigerant exit 520 are arranged on the first side of evaporimeter;
Concrete, described evaporimeter comprises:
In sum, it is high that the evaporimeter that the utility model provides has production efficiency, and product structure is firm, produces yield high, the advantage that heat exchange amount is high.
As shown in Figure 8, whole parallel-flow evaporator is divided into two runners, comprises first flow and the second runner.During air-conditioning system work, cold-producing medium flows into the first flow of header 100 by refrigerant import 510, by the equal discharge orifice 121 on header 100, cold-producing medium is carried out after current-sharing, liquid chamber pipe 200 in flowing into, harmonica-shaped tube 300 is connected with interior liquid chamber pipe 200, refrigerant flow into another interior liquid chamber pipe 200 of first flow through harmonica-shaped tube 300, pass through again the equal discharge orifice 121 on another header 100, flow in another header 100, first flow and the second runner are provided with runner connecting portion 600 in the end of another header 100, refrigerant enters the second runner by runner connecting portion 600, connect according to identical operation principle in first flow, finally from the refrigerant exit 520 of the second runner, flow out, enter compressor.This scheme production efficiency is high, and product structure is firm, produces yield high, and heat exchange amount is high.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
