The utility model provides an evaporator assembly and a refrigerator, and aims to solve the problems that in the prior art, when an evaporator exchanges heat with air in a refrigeration compartment, a heat exchange path is short and a heat exchange effect is poor.

An evaporator assembly according to an embodiment of the present utility model, as shown in fig. 1-7, comprises an evaporator 1 and a housing 2 cooperatively disposed around the evaporator, wherein the housing 2 includes an air inlet 241 and an air outlet 231 disposed at two ends of the evaporator in a first direction A1, side walls extending in the first direction A1 and disposed at side edges of the evaporator, and wind shields 3 extending from opposite side walls alternately into the housing, and two wind shields 3 disposed adjacent to each other in the first direction A1 are spaced apart, the side walls include opposite first side walls 21 and two second side walls 22 connecting two ends of the first side walls, one end of the wind shields 3 is connected to one of the first side walls 21, the other end extends toward the other first side wall 21, and a circulation channel for air supply is formed between the other first side walls 21.

In the present embodiment, the first direction A1 may be defined as a vertical direction, which is not limited in the present embodiment.

Generally, the housing 2 further includes two end surfaces located at two ends of the evaporator in the first direction A1, the two end surfaces including a first end surface 24 located below in the first direction A1 and a second end surface 23 located above in the first direction A1, the air inlet 241 is disposed on the first end surface 24, and the air outlet 231 is disposed on the second end surface 23.

In order to allow air to enter the housing 2 from the air inlet 241 located below, an air suction fan may be provided on the second end face 23, as will be appreciated.

Through the above arrangement, one end of the wind deflector 3 is connected to one of the first side walls 21, and the other end extends toward the other first side wall 21, and a circulation channel through which air flows is formed between the wind deflector and the other first side wall 21, so that when air in the refrigerating compartment of the refrigerator enters the housing 2 from the air inlet 241 located below, the air will flow in the circulation channel in a meandering manner, and the heat exchange path is greatly prolonged, thereby effectively improving the heat exchange effect.

Further, the distance d from the end of the wind deflector 3 provided on any one of the first side walls 21 away from the first side wall 21 to the first side wall 21 is not less than half the distance between the two first side walls 21 and not more than two thirds of the distance between the two first side walls 21.

Through many experimental measurements, when the above setting conditions are satisfied, the air duct defined between one end of the wind deflector 3, which is disposed on any one of the first side walls 21 and is far away from the first side wall 21, and the opposite other first side wall 21 has a better residence effect, and can ensure that air has a larger heat exchange path in the circulation channel.

It is to be understood that, when one end of the wind deflector 3 is connected to one of the first side walls 21 and the other end extends toward the other first side wall 21, and a flow channel through which the gas flows is formed between the other first side wall 21, both ends of the wind deflector 3 are respectively abutted against the second side wall 22.

Further, the plurality of wind deflectors 3 disposed on the two first side walls 21 are uniformly distributed along the first direction A1, and after this arrangement, the cross sections of the formed flow channels in the first direction A1 are substantially equal, so that the uniformity of the gas flow can be ensured.

Further, the wind deflector 3 is arranged to extend toward one of the two first side walls 21 and also toward the first end face 24 of the housing 2 located below in the first direction such that the wind deflector 3 forms an angle a with a plane perpendicular to the first direction A1, and the angle a is 5 to 45 °.

When defrosting the evaporator 1, the frost on the evaporator 1 can be melted into water droplets and drop onto the end face of the wind shield 3 above the first direction A1, and the arrangement of the included angle a is favorable for the water droplets to slide off from the wind shield 3.

Through a plurality of groups of experimental tests, when the included angle a formed by the wind shield 3 and the plane perpendicular to the first direction is 5-45 degrees, on one hand, the water drops condensed on the wind shield 3 can be ensured to slide off, and on the other hand, the circulation of the gas in the circulation channel can not be influenced.

When the included angle a formed by the wind deflector 3 and the plane perpendicular to the first direction is smaller than 5 degrees, the phenomenon that the water drops on the wind deflector 3 are difficult to slide can occur.

It will be appreciated that the wind deflector 3 and the first side wall 21 to which it is connected may form an angle of degree 90 ° -a, the angle being sharper as a larger angle of a.

According to the data obtained through experimental measurement, when the included angle a formed by the wind deflector 3 and the plane perpendicular to the first direction is greater than 45 degrees, that is, the included angle formed between the wind deflector 3 and the first side wall 21 connected with the wind deflector is smaller than 45 degrees, air in the circulation channel is retained at the included angle, which is not beneficial to circulation.

Preferably, in some embodiments, in order to make the water droplets condensed on the wind deflector 3 flow down from a specific position, a flow guide groove may be provided on the wind deflector 3, which is located on an end surface of the wind deflector 3 located above in the first direction A1.

The evaporator 1 generally includes a fin 11 and an evaporation coil 12 passing through the fin 11, and both sides of the evaporation coil 12 are connected to two second side walls 22.

In particular, the evaporator coil 12 includes a straight portion 121 and a curved portion 122 that are connected in series, and in some embodiments, the curved portion 122 may be directly connected to the inside of the second side wall 22, such that when connected, the evaporator coil 12 is entirely within the housing 2, thus eliminating the need for concern about sealing at the junction of the evaporator coil and the housing.

However, during the refrigerator manufacturing process, some of the evaporator coils 12 are also embedded in the second side wall 22.

Specifically, the straight portion 121 may be disposed between the two second side walls 22, and the straight portion 121 may be bent to form the bent portion 122 after passing through the second side walls 22.

Preferably, the straight portion 121 may be connected to the second side wall 22 in a sealing manner, so as to further ensure a heat exchange path when the gas circulates in the circulation channel, and avoid leakage from the gap.

The straight portion 121 and the second side wall 22 may be welded by sealing welding, or a sealing member such as a seal ring, a gasket, or the like may be disposed therebetween.

In order to ensure the thermal conductivity of the wind deflector 3 and the housing 2, the housing 2 and the wind deflector 3 may be made of aluminum or copper.

In some embodiments, the housing 2 is provided with a heating tube 4 inside the first end 24 located below in the first direction A1, and the end of the fin 11 located below in the first direction A1 is in contact with the heating tube 4. When defrosting is needed, the heating pipe 4 is started, and heat on the heating pipe 4 is transferred to the fins 11 and then transferred to the evaporation coil 12 through the fins 11, so that defrosting is achieved.

Yet another embodiment of the present utility model provides a refrigerator having the evaporator assembly as described above.

In summary, the following technical effects are achieved by the embodiments of the present utility model:

through the deep bead 3 that extends in the casing from two opposite first lateral walls 21 in turn, the interval sets up between two adjacent deep beads 3 in first direction A1, deep bead 3 one end is connected in one of them first lateral wall 21, and the other end extends towards another first lateral wall 21 direction to be formed with the circulation passageway that the air supplied gas circulates between the aforesaid another first lateral wall 21, after the air in the refrigerator refrigeration room gets into casing 2 from the air intake 241 that is located the below, the great extension of heat transfer route has improved the heat transfer effect effectively.
