Abstract

The utility model provides a butterfly double pin heat exchanger, two unit heat exchangers that the symmetry set up about including, unit heat exchanger end becomes the kink to one side bending type, the unit heat exchanger includes the hot traffic management way that comprises the hairpin pipe, and the pipeline outside is provided with heat and hands over the fin, and the pipeline end -to -end connection has electronic expansion valve. The utility model discloses butterfly double pin heat exchanger can mitigate the difference of the ten interior octuple refrigerant velocities of flow of heat exchanger, improves heat transfer effect and complete machine efficiency. Refrigerant subcooling once more after will converging reduces condensing temperature, improves the system reliability under extreme condition. The unit heat exchanger sets up the kink, the narrow space of make full use of unit, and the area is handed over to increase heat, optimizes the wind channel structure of machine simultaneously, effective noise reduction.

Description

A kind of butterfly Two bors d's oeuveres heat exchanger
Technical field
This utility model belongs to air-conditioning field of heat exchangers, particularly relates to a kind of Two bors d's oeuveres heat exchanger in industrial refrigeration in machine.
Background technology
Existing industrial heat-exchanger circuit design major part is for multiloop with entering with going out design, and import loop is consistent with outlet loop, and in small-sized air condition system, each loop refrigerant flow rate and pressure gap are not clearly.But industrial cabinet-type air conditioner typically in more than 10P, large-scale Industrial air conditioner system coolant storage more, and hot traffic control road is oversize, and the phenomenon that refrigerant flow rate is uneven between each loop, crushing is inconsistent is fairly obvious.In the case of each loop crushing is inconsistent, without process flow directly out hot intersection cause condenser to change shortage of heat, system energy efficiency low.The structure of heat exchanger mostly is flat, is inclined and mounted in cabinet-type air conditioner (with reference to Fig. 1), and its heat exchange area is less, under the harsh industrial environments such as high temperature, it may appear that heat exchange area is not enough, the situation of poor refrigerating efficiency.
Utility model content
This utility model uses slab construction heat exchange area little for the heat exchanger of machine in existing commercial refrigeration, multiloop is with entering with going out to cause the technical problem that refrigerant flow rate is uneven, crushing is inconsistent, a kind of heat exchange area is proposed big, on the basis of effectively reducing voltage loss, promote the butterfly Two bors d's oeuveres heat exchanger of complete machine efficiency, this heat exchanger optimizes the air channel structure that industry cabinet-type air conditioner is overall simultaneously, effectively reduces complete machine noise.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of butterfly Two bors d's oeuveres heat exchanger, including two the symmetrically arranged unit heat exchanger in left and right, unit heat exchanger end is bent to form kink to side, and described unit heat exchanger includes the hot traffic control road being made up of hair fastener pipe, being provided with heat outside pipeline and hand over fin, line end connects electric expansion valve.
As preferably, described kink and horizontal direction angle are 52 ° ~ 62 °.
As preferably, described kink and horizontal direction angle are 57 °.
Compared with prior art, advantage of the present utility model and having the active effect that
1, the difference of 18 road refrigerant flow rates in butterfly Two bors d's oeuveres heat exchanger can relax heat exchanger, improves heat transfer effect and complete machine efficiency.
2, the coolant after confluxing is the most supercool, reduces condensation temperature, improves the system reliability under extreme operating condition.
3, the unit heat exchanger of butterfly Two bors d's oeuveres heat exchanger arranges kink, optimizes the air channel structure of machine, effectively reduces noise.
4, butterfly Two bors d's oeuveres heat exchanger, makes full use of unit narrow space, increases hot cross surface and amasss.

Detailed description of the invention
In order to be better understood from this utility model, illustrate with embodiment below in conjunction with the accompanying drawings.
Embodiment: Fig. 1 is the installation diagram of industrial plate-type exchanger in prior art, and plate-type exchanger includes that the loop being made up of many hair fastener pipes is constituted, and surface, loop is provided with heat and hands over fin, and import loop is consistent with outlet loop.During installation, heat exchanger tilts to be installed in cabinet-type air conditioner, and heat exchanger upper end is fixed on cabinet-type air conditioner antetheca, and lower end is fixed on rear wall.Owing in large-scale Industrial air conditioner system, coolant storage is more, and hot traffic control road is oversize, and the phenomenon that between each loop, refrigerant flow rate is uneven, crushing is inconsistent is fairly obvious.
As shown in Figures 2 and 3, the present embodiment proposes a kind of butterfly Two bors d's oeuveres heat exchanger, including two the symmetrically arranged unit heat exchanger in left and right, unit heat exchanger end is bent to form kink to side, described unit heat exchanger includes the hot traffic control road being made up of hair fastener pipe, being provided with heat outside pipeline and hand over fin, line end connects electric expansion valve.Described kink is structure as a whole with front end plate part, and it is 57 ° that centre is set to sharp angle α folded by circular arc, kink place plane and flat part.The end of two unit heat exchanger arranges kink, and on the premise of cabinet-type air conditioner volume inconvenience, the heat exchange area of condenser adds about 30%, further increases heat exchange efficiency, more energy-conservation.Effectively prevent the problem that Conventional plate-type heat exchanger heat exchange area is little, heat exchange is insufficient.Have also been changed Windward angle simultaneously, optimize the air channel structure that industry cabinet-type air conditioner is overall, effectively reduce complete machine noise.Being separately provided loop and electric expansion valve in two heat exchanger plates, conventional chambers machine flat plate heat exchanger be divide into two independent heat exchangers, it is possible to neutralize the flow velocity difference of 18 road coolant, coolant distributes evenly.Serve raising condenser degree of supercooling, reduce the effect of condensator outlet temperature.On the basis of effectively reducing voltage loss, promote complete machine efficiency.
The above; it it is only preferred embodiment of the present utility model; it it is not the restriction that this utility model is made other form; any those skilled in the art are changed possibly also with the technology contents of the disclosure above or are modified as the Equivalent embodiments of equivalent variations is applied to other field; but it is every without departing from technical solutions of the utility model content; any simple modification, equivalent variations and the remodeling made above example according to technical spirit of the present utility model, still falls within the protection domain of technical solutions of the utility model.
