As shown in fig. 1 to 3, in one embodiment, the refrigeration apparatus 1 includes a housing 10 and a liner 20. The inner side of the inner container 20 defines a storage compartment 21, and the outer container 10 is sleeved outside the inner container 20, thereby forming a foaming layer between the outer container 10 and the inner container 20. The liner 20 is provided with a hollowed-out area 22.

With continued reference to fig. 1-3, the refrigeration appliance 1 further includes a plate and tube evaporator 30 and a temperature-conducting plate 40. The plate-tube evaporator 30 is attached to the outer side of the liner 20 and covers the hollow area 22, the heat-conducting plate 40 is attached to the inner side of the liner 20 and covers the hollow area 22, and a seal is formed between the heat-conducting plate 40 and the inner side of the liner 20 around the hollow area 22.

Specifically, the plate tube evaporator 30 includes an evaporation tube 31 and an evaporation plate 32, and the evaporation tube 31 is formed on the evaporation plate 32. The evaporation plate 32 is attached to the outer side wall of the liner 20, and the area of the evaporation plate 32 is larger than the area of the hollowed-out area 22, so that the evaporation plate 32 covers the hollowed-out area 22 from the outer side of the liner 20. The temperature-guiding plate 40 is attached to the inner side wall of the liner 20, and the area of the temperature-guiding plate 40 is larger than the area of the hollowed-out area 22, so that the hollowed-out area 22 is covered by the temperature-guiding plate 40 from the inner side of the liner 20.

In the solution of this embodiment, the hollowed-out area 22 is disposed on the liner 20, and the plate tube evaporator 30 and the heat conducting plate 40 cover the hollowed-out area 22 from the outside of the liner 20 and the inside of the liner 20 respectively, so that the plate tube evaporator 30 can transfer the cold energy to the heat conducting plate 40 through the hollowed-out area 22 during the working process of the refrigeration equipment 1, and then the heat conducting plate 40 transfers the cold energy to the storage compartment 21 to cool the storage compartment 21. That is, the plate tube evaporator 30 transfers the cold to the storage compartment 21 using the heat transfer plate 40 having a better heat transfer effect, thereby improving the cooling efficiency of the plate tube evaporator 30 and being advantageous to reduce the overall area of the plate tube evaporator 30.

In addition, because the seal is formed between the heat-conducting plate 40 and the liner 20, the water vapor in the storage compartment 21 cannot enter the area where the plate tube evaporator 30 and the foaming layer are located through the hollowed-out area 22, so that the plate tube evaporator 30 can be prevented from frosting to damage the foaming layer. At the same time, it is also possible to prevent the defrosting water on the heat transfer plate 40 from entering the foaming layer to cause a decrease in the heat insulation effect of the foaming layer or to directly cause damage to the heat insulation layer.

As shown in fig. 2, further, a first sealing structure 50 and a second sealing structure 60 are disposed between the heat conducting plate 40 and the inner container 20, the first sealing structure 50 surrounds the hollow area 22, and the second sealing structure 60 surrounds the first sealing structure 50.

As shown in fig. 3, in particular, the first sealing structure 50 includes a receiving groove 51 and a gasket 52. The accommodating groove 51 is formed on a side of the heat conductive plate 40 facing the hollowed-out area 22. The gasket 52 is disposed in the accommodating groove 51, and the gasket 52 is in sealing engagement with the heat-conducting plate 40 and with the liner 20.

Specifically, the gasket 52 is made of a waterproof material such as EPDM (Ethylene Propylene Diene Monomer ) sponge. The shape enclosed by the sealing pad 52 is similar to the shape of the hollowed-out area 22, and the area of the shape enclosed by the sealing pad 52 is larger than the area of the hollowed-out area 22, so that the sealing pad 52 can surround the periphery of the hollowed-out area 22.

Meanwhile, the shape of the receiving groove 51 is matched with the outer shape of the packing 52. Therefore, after the heat-conducting plate 40 is attached to the inner sidewall of the inner container 20, the accommodating groove 51 and the inner container 20 clamp the sealing pad 52 together, one side of the sealing pad 52 is in sealing attachment with the accommodating groove 51 (i.e. in sealing attachment with the heat-conducting plate 40), and the other side of the sealing pad 52 is in sealing attachment with the inner wall of the inner container 20, so that a seal is formed between the inner container 20 and the heat-conducting plate 40.

Referring to fig. 2 and 3, in particular, the second sealing structure 60 is waterproof double-sided tape, which surrounds the first sealing structure 50. One side of the second sealing structure 60 is sealed with the liner 20 in an adhesive manner, and the other side is sealed with the heat transfer plate 40 in an adhesive manner.

In the solution of the present embodiment, by providing the first sealing structure 50 surrounding the hollowed-out area 22 and the second sealing structure 60 surrounding the first sealing structure 50 between the heat-conducting plate 40 and the liner 20, a double seal is formed between the heat-conducting plate 40 and the liner 20, so as to be beneficial to ensuring the sealing effect between the heat-conducting plate 40 and the liner 20.

Further, by forming the first sealing structure 50 by the sealing gasket 52 and the accommodating groove 51 formed in the heat conducting plate 40, not only the assembly between the heat conducting plate 40 and the liner 20 can be positioned, but also the surface area of the heat conducting plate 40 facing the storage compartment 21 is increased to a certain extent, thereby increasing the contact area with air and being beneficial to improving the refrigerating efficiency.

By setting the second sealing structure 60 as waterproof double-sided tape, the function of fixing the heat-conducting plate 40 and the inner container 20 can be performed while the function of waterproof sealing is performed.

It should be noted that, the shape of the hollowed-out area 22 may be a rounded rectangle, or may be a square, a hexagon, or other shapes, and accordingly, the shapes of the first sealing structure 50 and the second sealing structure 60 may be adaptively adjusted.

It should be noted that a sealing structure such as a single seal or a triple seal may be employed between the liner 20 and the heat transfer plate 40.

As shown in fig. 2 and 3, in one embodiment, the refrigerating apparatus 1 further includes a plurality of fins 70, and the plurality of fins 70 are disposed on a surface of the heat transfer plate 40 facing the inner side of the liner 20. Specifically, a plurality of raised fins 70 are formed by punching holes in the fin plate. The fin plate is attached to the surface of the temperature-guiding plate 40 facing the inner side of the inner container such that the fins 70 face the storage compartment 21.

In the solution of this embodiment, by disposing the plurality of fins 70 on the side of the heat-conducting plate 40 facing the storage compartment 21, the plate-tube evaporator 30 can transfer the cooling capacity to the heat-conducting plate 40 and the plurality of fins 70 through the hollowed-out area 22, so that the heat-conducting plate 40 and the plurality of fins 70 transfer the cooling capacity to the storage compartment 21 to cool the storage compartment 21, and the plurality of fins 70 increase the contact area with the air, thereby improving the cooling efficiency of the evaporator.

As shown in fig. 2 and 3, in one embodiment, a recess 41 is disposed on a side of the heat conducting plate 40 facing away from the hollow area 22, the recess 41 is located in the hollow area 22, and an outer side surface of the recess 41 is attached to the plate tube evaporator 30.

Specifically, the portion of the heat conducting plate 40 located in the hollowed-out area 22 extends into the hollowed-out area 22. In other words, with reference to the surface of the heat-conducting plate 40 facing the hollow area 22, the portion of the heat-conducting plate 40 located in the hollow area 22 protrudes toward the hollow area 22. The portion of the heat conducting plate 40 located in the hollow area 22 is recessed toward the hollow area 22 with reference to the surface of the heat conducting plate 40 facing the storage compartment 21, so as to form a recess 41.

After the heat-conducting plate 40 and the liner 20 are assembled in place, the concave portion 41 extends into the hollowed-out area 22 and is attached to the portion of the plate tube evaporator 30 for covering the hollowed-out area 22.

In the solution of this embodiment, the portion of the heat-conducting plate 40 located in the hollowed-out area 22 is attached to the plate tube evaporator 30, so that on one hand, the cooling capacity of the plate tube evaporator 30 can be better transferred to the heat-conducting plate 40, thereby being beneficial to improving the cooling efficiency. On the other hand, the concave portion 41 not only increases the surface area of the surface of the heat transfer plate 40 facing the storage compartment 21, that is, increases the contact area with air, thereby contributing to an improvement in the cooling capacity exchange efficiency and thus the cooling efficiency.

Further, as shown in fig. 4, a plurality of fins 70 are provided in the recess 41. On the one hand, because the recess 41 is fitted with the plate tube evaporator 30, the cold is better transferred to the fins 70 and then into the storage compartment 21 by the fins 70. On the other hand, the recess 41 forms a certain accommodation space, and the plurality of fins 70 makes the shape at the recess 41 more complex. Therefore, the fins 70 and the concave portions 41 cooperate with each other so that the air can stay at the concave portions 41 for a longer time, which is advantageous for the air and the fins 70 to exchange the cold sufficiently.

As shown in fig. 3 and 4, in one embodiment, the plurality of fins 70 are distributed in a plurality of rows in the up-down direction, the fins 70 in each row are arranged obliquely, and the oblique directions of the fins 70 of the adjacent two rows are opposite. Specifically, in the present embodiment, the plurality of fins 70 are divided into three rows, the fins 70 in the uppermost row being inclined from the upper right to the lower left, the fins 70 in the middle row being inclined from the upper left to the lower right, and the fins 70 in the lowermost row being inclined from the upper right to the lower left.

In the solution of this embodiment, by distributing the plurality of fins 70 in a plurality of rows and making the inclination directions of the fins 70 in two adjacent rows opposite, the flow speed of air between the fins 70 can be slowed down, so that the residence time of air between the fins 70 is improved, and sufficient cold energy exchange can be performed between the air and the fins 70, thereby being beneficial to improving the refrigeration efficiency.

As shown in fig. 1 and 2, in one embodiment, the refrigeration appliance 1 further includes a cover 80 and a fan 90. The cover plate 80 covers the temperature guide plate 40 with a space therebetween. The blower 90 is disposed between the cover plate 80 and the temperature guide plate 40, and the blower 90 is located at an upper side of the plurality of fins 70.

Specifically, the cover plate 80 is disposed at a side of the heat transfer plate 40 facing the storage compartment 21 with a certain interval from the heat transfer plate 40 such that the blower fan 90 can be installed between the cover plate 80 and the heat transfer plate 40. And, the blower 90 is located above the plurality of fins 70.

Therefore, when the fan 90 is started, the fan 90 can make the air at the fins 70 flow upward, then flow from the space between the top of the cover plate 80 and the liner 20 to the side of the cover plate 80 away from the heat-conducting plate 40, and then flow from the space between the bottom of the cover plate 80 and the liner 20 to the fins 70 between the cover plate 80 and the heat-conducting plate 40 again, thereby forming a circulating air path (refer to the flow direction schematic line in fig. 1).

In the solution of the present embodiment, by providing the cover plate 80 and the blower 90 in the storage compartment 21, the blower 90 can form a circulating air flow in the storage compartment 21, so that the air flow continuously flows through the temperature guide plate 40 and the fins 70 to bring cold into the space of the whole storage compartment 21. In addition, the fan 90 can drive the cold air flow upward, so that the cold air is prevented from flowing to the bottom of the storage compartment 21 and sinking and concentrating to a certain extent, thereby facilitating the diffusion of the cold air flow in the storage compartment 21, and improving the refrigeration efficiency and the uniformity of the temperature in the storage compartment 21.

In addition, in the present embodiment, the temperature-guiding plate 40 is provided with the recess 41, and the plurality of fins 70 are provided in the recess 41. Further, the plurality of fins 70 are distributed in a plurality of rows in the up-down direction, the fins 70 in each row are arranged obliquely, and the oblique directions of the fins 70 of the adjacent two rows are opposite. The structure makes the air passage at the fins 70 more complex, thereby increasing the flowing time of the air flow at the fins 70, enabling the air flow to take away more cold, and further being beneficial to improving the refrigeration efficiency.

Referring to fig. 1 and 2, further, a top end of the cover plate 80 is provided with a bending portion adjacent to the liner 20, and a bottom end of the cover plate 80 is provided with a bending portion adjacent to the liner 20. That is, the top portion of the cover 80 is bent toward the liner 20, and the bottom portion of the cover 80 is bent toward the liner 20. So that the air flow can stay between the cover plate 80 and the temperature guide plate 40 for a longer time, so that the cold air is sufficiently exchanged.

Referring to fig. 1 and 2, in one embodiment, a seal is formed between the plate tube evaporator 30 and the liner 20 around the hollowed-out area 22, including applying a waterproof adhesive between the plate tube evaporator 30 and the liner 20, or bonding the plate tube evaporator 30 and the liner 20 together by ultrasonic welding.

In the solution of the present embodiment, by sealing the plate tube evaporator 30 and the liner 20, the sealing effect on the hollowed-out area 22 can be further improved, and the water vapor in the storage compartment 21 is prevented from entering the foaming layer.

Referring to fig. 3, in one embodiment, the plate tube evaporator 30 is provided with positioning holes 33, and the positioning holes 33 are formed on the evaporation plate 32. The outer side wall of the liner 20 is provided with a positioning column, and the positioning column is embedded into the positioning hole 33 after the plate tube evaporator 30 and the liner 20 are assembled in place. Therefore, the positioning holes 33 and the positioning posts can play a positioning role in the assembly of the tube evaporator 30 and the inner container 20.
