Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.

As shown in Fig. 2~Fig. 5, one of the utility model preferred embodiment provides a kind of evaporator, including at least one Heat exchanging part 10, each heat exchanging part 10 include end plate 1, collector pipe 2, heat exchanger tube 3, drip tray 4 and drain valve 5.

As shown in figure 5, heat exchanger tube 3 wears from end plate 1 and is assemblied on end plate 1, collector pipe 2 be located at end plate 1 it is outer, with Heat exchanger tube 3 is connected (with reference to shown in Fig. 2), and drain valve 5 is connected to the lowest part of heat exchanger tube 3, and drip tray 4 is located at drain valve 5 Lower section.Since drain valve 5 is directly picked out from the lowest part of heat exchanger tube 3, the water in heat exchanger tube 3 can be discharged, in low temperature In the case of will not be because, there are freezing and expansion during water, causing heat exchanger tube spalling in heat exchanger tube, causing machine breakdown and can not run.

Fig. 4 is the structure diagram of linear type evaporator, and linear type evaporator includes a heat exchanging part 10, the heat exchanging part 10 Including two end plates being oppositely arranged 1, several mounting holes (non-label) are provided on end plate 1, heat exchanger tube 3 is from the peace of end plate 1 Dress is worn in hole, is assemblied between two end plates 1.Collector pipe 2 is located at outside end plate 1, extends towards the bottom of heat exchanger tube 3, drip tray 4 Positioned at the lower section of drain valve 5, it is fixed on the bottom of end plate 1.

It is understood that the present embodiment does not limit the concrete form of evaporator, in other embodiments, evaporator is also It can be with A fonts evaporator or V-shaped evaporator etc., for example, structure diagrams of the Fig. 1 and Fig. 6 for A font evaporators, the A fonts The heat exchanging part 10 of evaporator includes two, and two heat exchanging part 10 are respectively the first heat exchanging part 10a and the second heat exchanging part 10b, and second The modes of heat exchanging part 10b at a certain angle are connected to one end of the first heat exchanging part 10a.

Fig. 6 and Fig. 7 is a kind of two evaporators provided of the utility model preferred embodiment, with one of embodiment no It is that drain valve 5 is connected to the lowest part of collector pipe 2 with part.

As shown in fig. 7, heat exchanger tube 3 wears from end plate 1 and is assemblied on end plate 1, collector pipe 2 is located at outside end plate 1, court The bottom extension of heat exchanger tube 3, drain valve 5 is connected to the lowest part of collector pipe 2, at this point, the lowest part of collector pipe 2 is to drip tray 4 Distance the distance of drip tray 4 is arrived no more than the lowest part of heat exchanger tube 3, drip tray 4 is located at the lower section of drain valve 5, drip tray 4 and It is provided with to install the gap of drain valve 5 between collector pipe 2.Since the distance of lowest part to the drip tray 4 of collector pipe 2 is little In heat exchanger tube 3 lowest part to drip tray 4 distance, drain valve 5 directly from the lowest part of collector pipe 2 pick out come, can make to change Water in heat pipe is discharged, at low temperatures will not be because, there are freezing and expansion during water, causing heat exchanger tube spalling in heat exchanger tube, making It can not be run into machine breakdown.

In the present embodiment, evaporator be A font evaporators, mode including the first heat exchanging part 10a and at a certain angle It is connected to the second heat exchanging part 10b of first heat exchanging part 10a one end.It is evaporated it is understood that evaporator can also be linear type Device or V-shaped evaporator etc., if the lowest part of collector pipe 2 to drip tray 4 distance no more than heat exchanger tube 3 lowest part to connecing The distance of water pond 4 is provided with to install the gap of drain valve 5 between drip tray 4 and collector pipe 2, drain valve 5 is made to be connected to collection The lowest part of water pipe 2.

Although the utility model is illustrated by specific embodiment, it will be appreciated by those skilled in the art that, not In the case of departing from the scope of the utility model, various conversion and equivalent substitute can also be carried out to the utility model.In addition, it is directed to Particular condition or material can do various modifications, without departing from the scope of the utility model to the utility model.Therefore, this reality Disclosed specific embodiment is not limited to new, and should include falling into the whole in the range of the utility model claims Embodiment.
