Specific embodiment

Below with reference to each attached drawing, the utility model is described in detail.

When existing evaporator is used in Teat pump boiler or air-conditioning, usually there is the uneven problem of evaporation.The applicant It is found by experimental study, is to cause evaporating by the wind of evaporator because Teat pump boiler and air-conditioning are top air-out formula Wind speed on each region of device is different, and the U-tube of existing evaporator is that integral type is evenly arranged, and which results in wind The big region of speed, evaporation is fast, and the region that wind speed is small, does not evaporate sufficiently, and each region evaporation is uneven, and evaporator cannot get It makes full use of, influences heat pump efficiency and system stability.It now proposes a kind of evaporator, is applicable to Teat pump boiler and air-conditioning etc. The structure of top air-out formula, by the way that different evaporation regions, the U-tube quantity and wind speed of each evaporation region are arranged on an evaporator In inverse ratio, evaporator is uniformly evaporated, to improve efficiency and system (work of Teat pump boiler and air-conditioning) Stability.

Referring to Fig. 1, the present embodiment provides a kind of evaporators 1, are arranged around blower.

Evaporator 1 includes that fixed device 11, U-tube 12 and fin, fin are fixed in U-tube 12.The setting of U-tube 12 exists On fixed device 11, for passing through for refrigerant.Evaporator is equipped with more than two evaporating areas 2, the U-tube that each evaporating area 2 is arranged 12 quantity and the wind speed for the wind for passing through the evaporating area 2 are inversely proportional, and are sequentially communicated to form pipe between the U-tube in each evaporating area Road is respectively provided with an import and one outlet, and the U-tube of different evaporation regions is not connected.

Evaporator be provided with more than two evaporating areas 2, and each evaporating area 2 be arranged U-tube 12 quantity with pass through The wind speed of the wind of the evaporating area 2 is inversely proportional, and due to the evaporating area big in wind speed, the refrigerant evaporation speed for being passed through U-tube is fast, therefore Only need to be arranged the lesser U-tube of quantity, in the small evaporating area of wind speed, the refrigerant evaporation for being passed through U-tube is relatively lower speed, because This needs to be arranged a fairly large number of U-tube, so that the problem that evaporation is uneven brought by the difference due to wind speed is balanced, thus The stability of raising system.

In the present embodiment, evaporator is in the heat pump or air-conditioning of top air-out formula, referring to fig. 2, generally top wind speed Greatly, more downward wind speed is gradually reduced, and the concentration of arrow represents wind speed size in figure, and arrow more intensively represents the wind in the region Speed is bigger.After tested, top wind speed is about more than or equal to 3.0m/s, and middle part wind speed is about 2.0-2.5m/s, and lower part wind speed is about Less than or equal to 1.5m/s.In the present embodiment, U-tube 12, which is shuttled, is fixed on fixed device 11.

Opposite with wind speed, the quantity of the U-tube 12 of underlying evaporating area 2 is not less than the evaporating area 2 being located above U-tube 12 quantity.

Referring to Fig. 1, evaporating area 2 includes the first evaporating area 21, the second evaporating area 22 and the third set gradually from top to bottom Evaporating area 23.The quantity of the U-tube 12 of second evaporating area 22 is more than or equal to the quantity of the U-tube 12 of the first evaporating area 21, third The quantity of the U-tube 12 of evaporating area 23 is more than or equal to the quantity of the U-tube 12 of the second evaporating area 22.
