Description

Evaporator assembly and refrigerator

Technical Field

The application relates to the technical field of heat exchange equipment, in particular to an evaporator assembly and a refrigerator.

Background

The evaporator is an important part of a refrigerating system of a household refrigerator, and is formed by connecting related parts such as an aluminum pipe, a refrigerant pipeline, a necessary connecting pipe and the like together in a welding, hot melt bonding and other modes. For example, the evaporator exchanges heat with the surrounding environment when the refrigerant flows in the refrigerant pipeline, so that the evaporator can absorb the waste heat from the interior of the refrigerator compartment to refrigerate the refrigerator.

In the related art, a fin evaporator is generally adopted to cool a refrigerator, when the refrigerator normally operates, wet air with higher temperature in the refrigerator is changed into dry cold air through an evaporator cavity under the action of a fan, and therefore the purpose of cooling food is achieved. In the process of hot air circulation, the fins can form resistance to air, and if the wind shielding structures are not added on two sides of the evaporator, part of hot air can be directly blown into the refrigerating chamber of the refrigerator from the position between the evaporator and the inner wall of the refrigerator, so that the heat exchange efficiency is lower. Therefore, the sponge is arranged on two sides of the evaporator in the related art, and the sponge is tightly attached to the inner wall of the refrigerator, so that air leakage of an air duct in the evaporator cavity can be prevented, and part of hot air is prevented from blowing into the refrigerating chamber of the refrigerator.

However, when the refrigerator runs for a long time, the surface of the evaporator is full of a frost layer, the refrigerator starts to defrost after the defrosting condition is reached, at the moment, partial defrosting water can be remained above the sponge and is blocked by the sponge and cannot be smoothly discharged, when the refrigerator refrigerates again after defrosting is finished, the water blocked by the sponge can be made into solid ice, the water is difficult to defrost again, and the ice can be gradually accumulated along with the increase of defrosting times, so that the product performance is affected.

The evaporator assembly 10 provided by the embodiment of the application may include a first side plate 11, a second side plate 12, a plurality of fins 13 and a refrigerant tube 14, where the first side plate 11 and the second side plate 12 are arranged at intervals side by side, the fins 13 are arranged between the first side plate 11 and the second side plate 12 at intervals side by side, and the refrigerant tube 14 penetrates through the first side plate 11, the fins 13 and the second side plate 12. It can be understood that air flow channels are formed between the fins 13 arranged at intervals, and air can flow through the air flow channels (as shown by thick solid arrows in fig. 1), so that when the refrigerant in the refrigerant pipe 14 exchanges heat, heat conduction can be performed through the fins 13 and the refrigerant pipe 14, so that the heat exchange efficiency of the refrigerant agent and the surrounding environment is improved, and the hot air can be cooled after the fins 13 are popular. It can be appreciated that the refrigerant pipe 14 may be in communication with a compressor, and the refrigerant agent circulates in the refrigerant pipe 14 under the action of the compressor.

The refrigerant pipe 14 may be curved, and the refrigerant pipe 14 includes a plurality of bending sections, which may be understood as that the refrigerant pipe 14 is serpentine, so that the length of the sub-refrigerant pipe 14 may be increased as much as possible in a limited space, so as to increase the circulation path of the refrigerant agent and improve the heat exchange effect.

The first side plate 11 may include a first body 111 and a first wind shielding part 112, the first wind shielding part 112 being connected to an end of the first body 111, the first wind shielding part 112 protruding from a side of the first body 111 facing away from the second side plate 12. The second side plate 12 may include a second body 121 and a second wind shielding part 122, and the second wind shielding part 122 is connected to an end of the second body 121 and protrudes from a side of the second body 121 facing away from the first side plate 11. It will be appreciated that a plurality of fins 13 are disposed between the first body 111 and the second body 121. The refrigerant pipe 14 penetrates the first body 111, the fins 13, and the second body 121.

In the protruding direction along the first wind shielding portion 112, there is a first gap 15 between the first wind shielding portion 112 and the inner wall of the refrigerator, the first gap 15 being smaller than the interval between the adjacent fins 13. In the protruding direction along the second wind shielding portion 122, there is a second gap 16 between the second wind shielding portion 122 and the inner wall of the refrigerator, the second gap 16 being smaller than the spacing between the adjacent fins 13. It will be appreciated that the housing includes first and second walls 21, 22 forming the evaporator chamber, the first and second walls 21, 22 being disposed opposite each other, the first wall 21 being disposed opposite the first side plate 11 as shown in fig. 2 and 3, and the first gap 15 being understood to be a gap between the first wind shielding portion 112 and the first wall 21. The second chamber wall 22 is disposed opposite the second side plate 12, and the second gap 16 may be understood as a gap between the second wind shielding portion 122 and the second chamber wall 22.

Through setting up first keep out wind portion 112 and second keep out wind portion 122 to first clearance 15 between the inner wall of first keep out wind portion 112 and refrigerator is less than the interval between the adjacent fin 13, and second clearance 16 between the inner wall of second keep out wind portion 122 and refrigerator is less than the interval between the adjacent fin 13, so, when the evaporator assembly 10 is installed in the refrigerator, the second keep out wind portion 122 of first keep out wind portion 112 of first curb plate 11 and second curb plate 12 can be in the hot air circulation in-process, hinder the hot air to flow out from the space beyond fin 13, thereby make more hot air can flow through the gap between fin 13 in order to carry out heat exchange refrigeration, has improved the efficiency of heat transfer. In addition, due to the presence of the first gap 15 and the second gap 16, when the refrigerator is defrosted, the frost condensed on the first wind shielding portion 112 and the second wind shielding portion 122 can flow out from the first gap 15 and the second gap 16 after being defrosted, and the defrosted water is prevented from remaining on the first wind shielding portion 112 and the second wind shielding portion 122 to be repeatedly frosted.

In order to ensure that the wind resistance of the first gap 15 and the wind resistance of the second gap 16 are greater than the wind resistance of the air flow passage formed between the fins 13, only a small amount of wind can be blown out through the first gap 15 and the second gap 16, and the size of the first gap 15 may be set to 5 mm or less and the size of the second gap 16 may be set to 5 mm or less. In this way, it is ensured that not only is the defrost water flowing out of the first and second gaps 15, 16, but also that more air can flow through the air flow path between the fins 13.

In addition, since the first wind shielding part 112 is connected to the end of the first body 111 and the second wind shielding part 122 is connected to the end of the second body 121, the first wind shielding part 112 and the second wind shielding part 122 do not occupy the middle positions of the first body 111 and the second body 121, and are more suitable for the arrangement of other parts such as cables.

Illustratively, the first and second wind shielding portions 112 and 122 may be located on the same side of the evaporator assembly 10, such as at an upper end of the evaporator assembly 10 in a gravitational direction, such that the arrangement of other components such as cables below the first and second wind shielding portions 112 and 122 is not hindered, and the flow of defrost water out of the first and second wind shielding portions 112 and 122 under the force of gravity is facilitated.

Wherein, the first wind shielding part 112 and the first body 111 are integrally formed, and the second wind shielding part 122 and the second body 121 are integrally formed. It can be appreciated that when the first wind shielding part 112 and the first body 111 are of a split structure, the first wind shielding part 112 and the first body 111 are connected to the first body 111 by riveting or other connection methods, a connection gap is inevitably generated, so that water is easy to frost at the connection gap, and the connection strength between the first wind shielding part 112 and the first body 111 can be affected in the process of repeatedly frosting and defrosting, based on which the first wind shielding part 112 and the first body 111 are integrally formed, so that the connection gap between the first wind shielding part 112 and the first body 111 cannot be generated, and the connection strength between the first wind shielding part 112 and the first body 111 cannot be affected by frosting and frosting, and similarly, the second wind shielding part 122 and the second body 121 are also similar.

For example, the first side plate 11 and the second side plate 12 may be made of a metal material, and the end portion of the first side plate 11 may be bent by punching to form the first wind shielding portion 112, and the end portion of the second side plate 12 may be bent to form the second wind shielding portion 122. The process is simple and easy to operate.

It will also be appreciated that the integrally formed first wind shield portion 112 and first body 111 facilitate heat transfer, such as heating the first body 111 when melting frost on the first wind shield portion 112 is desired, and heat from the first body 111 can be transferred to the first wind shield portion 112 to melt frost on the first wind shield portion 112. The same applies to the second wind shielding portion 122 and the second body 121 integrally formed.

In some embodiments, referring to fig. 4 and fig. 5, fig. 4 is a second structural schematic diagram of the first side plate and the first cavity wall provided in the embodiment of the present application, and fig. 5 is a second structural schematic diagram of the second side plate and the second cavity wall provided in the embodiment of the present application.

In this way, under the action of gravity, the defrost water at the first wind shielding portion 112 may flow out of the first gap 15 along the first wind shielding portion 112, and the defrost water at the second wind shielding portion 122 may flow out of the second gap 16 along the second wind shielding portion 122.

It will be appreciated that when water frosts the first and second wind shielding parts 112 and 122, defrosting by heat is required to melt the frost into frost water. Based on this, as shown in fig. 1, the evaporator assembly 10 may further include a heater 17, the heater 17 for providing heat to the first side plate 11 and the second side plate 12.

Wherein, in order to facilitate the installation of the heater 17, the evaporator assembly 10 may further comprise a carrier plate 18, and the heater 17 is installed on the carrier plate 18. It will be appreciated that the carrier plate 18 may be disposed within a refrigerator, such as within an evaporator chamber. The first side plate 11, the second side plate 12, the fins 13, and the heater 17 are provided to the carrier plate 18, respectively.

To receive the defrost water flowing out of the first and second gaps 15, 16, the evaporator assembly 10 may further include a water tray 19, the water tray 19 being located below the first and second gaps 15, 16 in the direction of gravity. Wherein, the water pan 19 can be installed in the carrier plate 18, and the carrier plate 18 can be provided with a water outlet 181 communicated with the water pan 19, so that water in the water pan 19 can be discharged through the water outlet 181.
