Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The application provides an evaporator assembly, and particularly relates to the evaporator assembly applied to an air-cooled refrigerator.

Referring to fig. 1 and 2, in the embodiment of the present application, the evaporator assembly 100 includes an evaporator 10.

The evaporator 10 is used for being installed in an evaporation chamber (or a freezing air duct) of an air-cooled refrigerator, and as shown in fig. 2, the evaporator 10 is formed by connecting a plurality of rows of S-shaped evaporation tubes. When air in the storage chamber is blown to the surface of the evaporator 10, the air is in sufficient contact with the surface of the evaporator 10 to exchange heat, thereby reducing the temperature of the air.

And often there is moisture in the air in the apotheca, moisture in the air in the apotheca gets into after getting into the evaporating chamber through cold wind circulation, because evaporimeter 10 surface temperature is lower, moisture in the air can be at evaporimeter 10 surface condensation frost, leads to the heat transfer effect variation of evaporimeter 10, leads to the operating time extension of compressor, increases the consumption of refrigerator, so in this application embodiment, evaporimeter subassembly 100 still includes heating pipe 20, and heating pipe 20 installs in one side of evaporimeter 10.

In the embodiment of the present application, the heating tube 20 is electrically heated, and the heating tube 20 generates heat when being powered on, so that the frost condensed on the surface of the evaporator 10 is melted. Wherein, the heating pipe 20 can be fixed on the side of the evaporator 10 by the mounting structure, and at this time, the heat generated by the heating pipe 20 can be conducted to the evaporator 10 by the mounting structure and the air; the heating pipe 20 may be spaced apart from the evaporator 10 (i.e., not in contact with the evaporator), and the heat generated by the heating pipe 20 is transferred to the evaporator 10 only through the air.

For the reason that the heating pipe 20 is installed at the side of the evaporator 10, the heat generated at the side of the heating pipe 20 away from the evaporator 10 is dissipated to the air away from the evaporator 10, resulting in a part of the heat loss generated by the heating pipe 20, and the heat utilization efficiency of the heating pipe 20 is reduced, in the embodiment of the present application, in order to improve the heat utilization efficiency of the heating pipe 20, please refer to fig. 3 to 5 in combination, the heating pipe 20 includes a pipe body 21, and a heating portion 23 and a heat insulating portion 24 which are arranged in the pipe body 21, the heating portion 23 is arranged close to the evaporator 10, and the heat insulating portion 24 is arranged away from the evaporator 10.

It can be understood that, by disposing the heat generating portion 23 in the tube 21 near the evaporator 10 and disposing the heat insulating portion 24 in the tube 21 far from the evaporator 10, the heat insulating portion 24 weakens the heat generated by the heat generating portion 23 to be transferred to the side of the tube 21 far from the evaporator 10, so that the heat generated by the heat generating portion 23 is concentrated on the side of the tube 21 (the heating tube 20) near the evaporator 10, compared with the conventional heating tube, most of the heat generated by the heating tube 20 of the embodiment of the present application is transferred to the evaporator 10, and the heat dissipated to the air around the evaporator 10 is reduced, thereby reducing heat loss, improving the heat utilization efficiency of the heating tube 20, accelerating the melting of the frost on the surface of the evaporator 10, reducing the working time of the compressor, and reducing the energy consumption of the refrigerator.

Since the heating portion 23 does not completely fill the inner cavity of the tube 21, in order to facilitate the installation of the heating portion 23 into the tube 21, in an embodiment, referring to fig. 4, the heating tube 20 further includes a partition 22, the partition 22 is disposed in the tube 21 and partitions the inside of the tube 21 into a first tube cavity (not labeled) and a second tube cavity (not labeled), the first tube cavity is close to the evaporator 10, the second tube cavity is far from the evaporator 10, the heating portion 23 is disposed in the first tube cavity, and the heat insulation portion 24 is disposed in the second tube cavity.

It can be understood that, by providing the partition 22 in the tube 21 to partition the inside of the tube 21 into the first and second lumens, the heat generating portion 23 and the heat insulating portion 24 can be respectively and conveniently installed in the tube 21, so as to prevent the heat generating portion 23 and the heat insulating portion 24 from interfering with each other during assembly, ensure that the heat generating portion 23 of each portion in the tube 21 is located on the side of the tube 21 close to the evaporator 10, and ensure that the heat insulating portion 24 of each portion in the tube 21 is located on the side of the tube 21 away from the evaporator 10; meanwhile, the first and second lumens are not communicated with each other under the partition of the partition 22, so that the heat generating portion 23 and the heat insulating portion 24 are limited, and the heat generating portion 23 of the first lumen is prevented from entering the second lumen by an external force (e.g., when the heating pipe 20 is bent).

Wherein, the partition 22 and the tube 21 are an integral structure. Specifically, the partition 22 and the pipe body 21 can be integrally formed through a metal extrusion process; in the embodiment of the present application, the material of the tube body 21 is preferably aluminum because aluminum has better ductility, better plastic flow during extrusion, and easy extrusion molding from a specific mold under extrusion.

In one embodiment, in order to ensure that the heating tube 20 emits sufficient heat to be conducted to the evaporator 10, the cross-sectional area of the heat generating portion 23 in the radial direction of the tube body 21 is greater than or equal to the cross-sectional area of the heat insulating portion 24 in the radial direction of the tube body 21.

For example, in order to facilitate the production and processing of the heating pipe 20, it is preferable that the cross-sectional area of the heat generating portion 23 in the radial direction of the pipe body 21 is equal to the cross-sectional area of the heat insulating portion 24 in the radial direction of the pipe body 21; in this way, the partition 22 can be disposed on the middle line of the tube body 21, thereby facilitating the manufacturing process of the heating tube 20.

In this embodiment, referring to fig. 3 and 4, the heat generating portion 23 includes a heat generating body 231 and an insulating heat conductor 232, the heat generating body 231 is disposed at an interval with the cavity wall of the first cavity, and the insulating heat conductor 232 covers the heat generating body 231 and contacts with the cavity wall of the first cavity.

The heating element 231 may be a metal conductive wire, and the insulating heat conductor 232 covers the heating element 231 to prevent the heating element 231 from contacting the inner wall of the pipe body 21, and in the energized state, the heating element 231 generates heat and conducts heat to the pipe body 21 through the insulating heat conductor 232. The insulating heat conductor 232 is a silicon rubber insulating layer.

In one embodiment of the present application, the second lumen is filled with a heat insulating material to form the heat insulating portion 24.

Wherein the heat insulating material may be foam, rock wool, etc. The heat insulating material is filled in the second cavity to insulate heat, so that heat generated by the heat generating part 23 is prevented from being transferred to the second cavity through the partition plate 22, the heat generated by the heat generating part 23 is prevented from being transferred to the side, away from the evaporator 10, of the tube body 21, and heat loss is reduced.

In another embodiment of the present application, a vacuum is drawn within the second lumen to form the insulation 24.

Similarly, the heat generated by the heat-generating portion 23 blocked by the vacuum environment is transmitted to the second tube cavity through the partition 22, so that the heat generated by the heat-generating portion 23 is prevented from being transmitted to the side of the tube body 21 away from the evaporator 10, and the heat loss is reduced.

Referring to fig. 1 and 5, in the embodiment of the present application, the evaporator assembly 100 further includes a plurality of fins 30, the plurality of fins 30 are spaced apart from each other, and the evaporator 10 penetrates through the plurality of fins 30.

Specifically, the evaporator 10 includes a plurality of evaporation tubes, each fin 30 is provided with a plurality of through holes for the plurality of evaporation tubes to pass through, and each evaporation tube is inserted through the corresponding through hole and contacts with the side wall of the fin 30 forming the through hole.

Wherein, the side of at least one fin 30 is provided with a clamping groove 31, and the heating pipe 20 is clamped in the clamping groove 31.

Optionally, in an embodiment, a clamping groove 31 is disposed on a side wall of each fin 30, and the heating pipe 20 is clamped in the plurality of clamping grooves 31.

By clamping the heating pipe 20 to the clamping groove 31, that is, the heating pipe 20 is indirectly connected with the evaporation pipes through the fins 30, when the heating pipe 20 is powered on to generate heat, the heat generated by the heating pipe 20 is transferred to each evaporation pipe through the fins 30, and compared with the heat generated by only diffusing heat through air, because the heat conductivity coefficient of the fins 30 is high, the heat generated by the heating pipe 20 can be rapidly transferred to the evaporation pipes, and the melting speed of frost on the surface of the evaporator 10 is accelerated; moreover, the heat generated by the heating tube 20 can be transferred to the evaporation tube far away from the heating tube 20 by the heat conduction function of the fins 30, so that the frost on the surface of the evaporator 10 can be melted.

As shown in fig. 5, the locking groove 31 is formed by extending from a side edge of the fin 30 toward the inside of the fin 30, that is, the locking groove 31 is an open groove, so as to facilitate the locking of the heating tube 20 into the locking groove 31.

In order to further improve the defrosting efficiency of the evaporator 10, in an embodiment of the present application, referring to fig. 1, the number of the heating pipes 20 is two, and the two heating pipes 20 are oppositely disposed on two opposite sides of the evaporator 10.

It can be understood that, by providing two heating pipes 20 on two opposite sides of the evaporator 10, when the evaporator is powered on, the two heating pipes 20 conduct heat to the evaporator 10 at the same time, so as to avoid that the temperature of one side of the evaporator 10 is higher and the temperature of the other side is lower, so that the heat applied to the evaporator 10 is approximately uniform, and the defrosting efficiency of the evaporator 10 is further improved.

Referring to fig. 1, in an embodiment, a connecting pipe 40 is further included, and the connecting pipe 40 is connected between the two heating pipes 20.

It can be understood that the assembling speed of the heating pipe 20 to the fin 30 can be increased by connecting the connecting pipe 40 between the two heating pipes 20 so that the two heating pipes 20 are connected as a whole; moreover, because two heating pipes 20 are respectively connected to the locking grooves 31 on the two opposite sides of the fins 30, the two heating pipes 20 are connected through the connecting pipe 40, the heating pipe 20 can be wholly limited in the horizontal direction, when one of the heating pipes 20 is subjected to the tendency that the external force is generated to separate from the corresponding locking groove 31, due to the connection effect of the connecting pipe 40, the other heating pipe 20 also receives the acting force in the direction, and at the moment, the other heating pipe 20 is tightly abutted to the locking groove 31 corresponding to the other heating pipe 20 under the acting force, the whole heating pipe 20 is prevented from moving towards the direction, so that the stable locking of the heating pipe 20 on the fins 30 is ensured, and the heating pipe 20 is prevented from easily separating from the fins 30 and dropping.

Alternatively, in one embodiment, the connecting tube 40 is integrally formed with the heating tube 20.

In the embodiment of the present application, the heating pipe 20 is disposed in an S-shape.

As shown in fig. 1 and 2, by arranging the heating pipe 20 in an S shape, heat generated by the heating pipe 20 is transferred to each fin 30, so that the heat is uniformly transferred to the evaporator 10, and the evaporator 10 can be uniformly heated by the heating pipe 20 everywhere.

The embodiment of the application also provides an air-cooled refrigerator, which comprises a refrigerator body and a refrigerating system arranged in the refrigerator body, wherein the refrigerating system comprises the evaporator assembly 100 based on the design concept.

Since the air-cooled refrigerator employs the evaporator assembly 100 based on the above design concept, the evaporator assembly 100 arranges the heat generating portion 23 in the pipe 21 at a position close to the evaporator 10, and arranges the heat insulating portion 24 in the pipe 21 at a position away from the evaporator 10, and during the heating process of the heating pipe 20, the heat insulating portion 24 weakens the transmission of the heat generated by the heat generating portion 23 to the side of the pipe 21 away from the evaporator 10, so that the heat generated by the heat generating portion 23 is concentrated on the side of the pipe 21 (the heating pipe 20) close to the evaporator 10, compared with the conventional heating pipe 20, most of the heat generated by the heating pipe 20 of the embodiment of the present application is transmitted to the evaporator 10, and the heat emitted to the air around the evaporator 10 is reduced, thereby reducing the heat loss, improving the heat utilization efficiency of the heating pipe 20, accelerating the frost melting on the surface of the evaporator 10, reducing the working time of the compressor, and reducing the energy consumption of the refrigerator.
