Device.
In a preferred embodiment, the heating tube and the defrost branch 3 are interference fit.Specifically, the heating tube
It is passed through for the outlet end of defrost branch 3, also, the heating tube will not be carried out around the axis of defrost branch 3 in left and right and circumferential direction
Rotation, that is, the heating tube can be securely fixed on the defrost branch 3.In this way, passing through so that the heating tube and defrost branch
Road 3 be interference fit so that heating tube can be positioned on defrost branch 3 it is stronger, that is, the heating tube exists
The shaking axially, radially and in circumferential direction will not occur on the defrost branch 3.Further, heating tube is considerably reduced
With the frictional force between defrost branch 3, meanwhile, also efficiently avoid because heating tube can opposite defrost branch 3 shaking, from
And the case where abrasion is caused to defrost branch 3.
In a preferred embodiment, which includes spiral type heated pipe or spring heating tube, wherein the spiral shell
Rotating heating tube or the spring heating tube are set in the defrost branch 3 on the pipeline at 21 position of entrance of the evaporator 2.
It should be noted that by the way that the heating tube is arranged to spiral or spring, to considerably increase the heating tube and change
The contact area of white branch 3, so that the heat transfer area of the heating tube Yu defrost branch 3 is effectively increased, when improving unit
Interior heat transfer efficiency, so that high temperature refrigerant can be heated rapidly in a short time.
In another preferred embodiment, the spiral type heated pipe or the internal diameter of the spring heating tube and the defrost branch
The outer diameter on road 3 is equal.In this way, passing through so that the spiral type heated pipe or the internal diameter of the spring heating tube and the defrost branch 3
Outer diameter it is equal so that the appearance of the spiral type heated pipe or the inner surface of spring heating tube and defrost branch 3
Face can be in close contact, and guaranteed heat exchange, so that the temperature of high temperature refrigerant continues to heat up, further, effectively ensured to enter
High temperature refrigerant temperature with higher inside evaporator 2 can reach and carry out quickly defrosting to evaporator 2 in a short time
Purpose, that is, the frost layer on the outer surface for condensing in evaporator 2 is heated as early as possible and is melted, meanwhile, so that after melting
Frost layer can fall off as soon as possible.
As shown in Figure 1, it further includes the second pipeline 6 that the defroster system is also schematically shown in figure, second pipe
Road 6 and the defrost branch 3 are in parallel setting, and the entrance of second pipeline 6 is connected to by triple valve 7 with the defrost branch 3.It needs
It is noted that the setting of the triple valve 7, may be implemented the switching of refrigeration and two kinds of operating modes of defrost.Specifically, by cutting
Change the circulation path of triple valve 7, that is, when triple valve 7, which is switched to, to be connected to the second pipeline 6, then the refrigeration of system may be implemented
Mode.When triple valve 7, which is switched to, to be connected to defrost branch 3, then the defrost pattern of system may be implemented.
It should be noted that the concrete operating principle of triple valve 7 be it is well known to those skilled in the art, for save length rise
See, is not detailed herein.
In another preferred embodiment, which further includes the condensation being arranged on second pipeline 6
