In the conventional heat exchange system of the refrigerator, the fin evaporator for refrigeration is liable to frost. Defrosting has become an important problem to be solved by refrigerators. In the prior art, a fin evaporator for refrigeration is arranged at the upper part, and a steel tube heater for defrosting is arranged at the lower part, so that the aim of removing frost on a fin heat exchanger is fulfilled. However, the steel tube heater may cause the ice on the uppermost surface of the fin evaporator to be unable to be completely melted below, which affects the refrigerating effect of the refrigerator.

Therefore, the present application proposes a fin evaporator assembly 10, which is an improvement of the existing refrigeration and defrosting combination, and the steel tube heater is inlaid in the fin 110 evaporator, and such a structural combination can effectively melt the frost on the surface of the fin 110 evaporator.

Specifically, as shown in fig. 1 and 4, an embodiment of the present application proposes a fin evaporator assembly 10, including:

an evaporator body 100, the evaporator body 100 having a first direction; the evaporator body 100 includes an evaporation tube 120 and a plurality of fins 110; the fins 110 are sequentially arranged at intervals along the first direction, and the evaporating pipes 120 penetrate through the fins 110; and

the heating pipes 200 are arranged in the fins 110 in a penetrating manner, and are arranged at intervals with the evaporating pipes 120.

In the technical scheme of this application, heating pipe 200 wears to establish in the fin 110 on the evaporimeter body 100 and with evaporating pipe 120 interval setting, directly heat fin 110 through the mode of heat conduction for fin 110 is evenly heated, reduces the temperature gradient of fin 110, makes the frost on the fin 110 surface can be got rid of completely, improves the refrigeration effect of refrigerator.

In addition, in the structure of the prior art, a steel tube heater needs to be arranged at the lower side of the fin 110 evaporator, so that the occupied space of the refrigerator is increased, and the volume of the freezing chamber is reduced; in the technical scheme of the application, the heating pipe 200 is arranged in the fins 110, so that the space of the fins 110 is effectively utilized, the space of the refrigerator is saved, and the capacity of the freezing chamber is improved.

In addition, in the structure of the prior art, since the steel tube heater heats the fins 110 in a heat radiation manner, the heating efficiency is low, which is not beneficial to saving electric energy; moreover, to sufficiently melt the frost on the fins 110, it is necessary to heat the temperature of the steel pipe heater to a high temperature, so that the temperature of the fins 110 near the steel pipe heater is increased, and there is a safety risk of overheating. In the technical scheme of the application, the heating pipe 200 is arranged in the fin 110, and is in direct contact with the fin 110, so that the heating efficiency is higher; and can make fin 110 evenly be heated, need not to heat the temperature of steel pipe heater to higher temperature, can reach the purpose of defrosting, have higher security.

As an alternative to the above embodiment, as shown in fig. 2, the evaporator body 100 further has a second direction and a third direction intersecting the first direction. In the specific implementation process, the first direction is the length direction, the second direction is the height direction, and the third direction is the width direction. As shown in fig. 6, the evaporation tube 120 includes a plurality of evaporation sections 121 penetrating the fins 110, and the evaporation sections 121 are spaced apart in the second direction and/or the third direction. For example, the plurality of evaporation nodes 121 may be disposed at intervals along the second direction; or a plurality of evaporation nodes 121 may be provided at intervals in the third direction. Generally, to enhance the cooling effect, the evaporator nodes 121 construct a serpentine arrangement of coils. For example, the evaporation nodes 121 are arranged in a plurality of rows in the second direction and two columns in the third direction. The evaporation sections 121 arranged along a row are arranged in a serpentine shape. The two evaporation nodes 121 at the lowermost side of the evaporator body 100 are connected by one transition node. The evaporator tube 120 further comprises a curved section 122 for connecting adjacent evaporator sections 121.

In an embodiment, as shown in connection with fig. 2 and 5, the heating tube 200 includes a plurality of heating segments 210 penetrating the fins 110. A plurality of the heating sections 210 are spaced apart in the second direction and/or the third direction. In general, the heating joints 210 may be spaced apart along the second direction; alternatively, the heating nodes 210 may be disposed at intervals along the third direction. In the case where the fins 110 have a large accommodating space, the heating joints 210 are provided with a plurality of rows in the second direction and a plurality of columns in the third direction. In order to reduce the thermal influence of the heating section 210 on the evaporation section 121, any one of the heating section 210 and any one of the evaporation section 121 are arranged in a staggered manner in the second direction and/or the third direction. Namely: in the fin 110, the heating section 210 and the evaporation section 121 are disposed in a contactless manner.

For this reason, in an embodiment, as shown in fig. 3, the fin 110 is provided with a plurality of first fixing holes 110a, and the plurality of first fixing holes 110a are spaced apart along the second direction and/or the third direction. The evaporation section 121 is embedded in the first fixing hole 110 a. Therefore, a plurality of the evaporation sections 121 are arranged at intervals in the second direction and/or the third direction. In the embodiment, each evaporation section 121 is embedded in the corresponding first fixing hole 110a of each fin 110. The evaporation joint 121 and the fin 110 are abutted against each other.

The fin 110 is further provided with a plurality of second fixing holes 110b, and the second fixing holes 110b are spaced along the second direction and/or the third direction; the heating section 210 is embedded in the second fixing hole 110 b. Accordingly, a plurality of the heating nodes 210 are spaced apart in the second direction and/or the third direction.

Any one of the first fixing holes 110a and any one of the second fixing holes 110b are arranged in a staggered manner in the second direction and/or the third direction. Any one of the heating sections 210 and any one of the evaporating sections 121 are arranged in a staggered manner in the second direction and/or the third direction.

And/or any one of the heating sections 210 forms a triangular array with its two evaporating sections 121 adjacent in the third direction. That is, in the embodiment, the adjacent two evaporation sections 121 of the same column are arranged in a triangular array with the adjacent heating sections 210; adjacent two evaporation sections 121 of the same row are also arranged in a triangular array with adjacent heating sections 210. In this arrangement, the spatial distance between the heating section 210 and the evaporation section 121 can be adjusted.

In some embodiments, referring to FIG. 2, four heating segments 210 are provided in a quadrilateral configuration. The evaporation node 121 may be disposed at a central position of the quadrangle. For example, four heating sections 210 may be arranged in a parallelogram, and evaporation section 121 may be arranged at the intersection of two diagonals of the parallelogram (evaporation section 121 substantially coincides with the intersection). So arranged, the heat generated by each heating section 210 can melt the frost layer of the adjacent four evaporation sections 121 and the surrounding areas thereof, thereby improving defrosting capability.

The fins 110 have a larger size in the height direction (second direction) and a relatively smaller size in the width direction (third direction), and therefore, in general, the plurality of heating sections 210 are disposed at intervals in the second direction, so that the fins 110 can be heated uniformly in the height direction to defrost the surface thereof. In an embodiment, the plurality of heating segments 210 are generally uniformly disposed in the second direction. As shown in fig. 5, the heating tube 200 further includes a plurality of bending joints 220; adjacent two heating sections 210 are connected by the bending section 220.
