The utility model provides an evaporator assembly and refrigeration equipment with the evaporator assembly.

Referring to FIG. 1 , FIG. 2 , and FIG. 4 , in an embodiment of the present invention, the refrigerating equipment that the evaporator assembly is suitable for is specifically a refrigerator (not shown). The evaporator assembly includes an evaporator 1 and a defrosting heating device arranged at the bottom of the evaporator 1 . Wherein, the evaporator 1 includes a heat exchange coil 11 and a plurality of fins 12 installed on the heat exchange coil 11; The lower part is in contact with the fin 12 at the piercing position. In this embodiment, the heating pipe sections 31 are arranged in parallel. Of course, the heating pipe sections 31 may also be arranged in a crossing manner, or in other ways, which are not limited here.

It should be noted here that, in the technical solution of the present utility model, the evaporator 1 also includes a side plate 2 for supporting the heat exchange coil 11 and preventing the fins 12 from falling off, and the side plate 2 includes The first side plate 21 and the second side plate 22 at both ends of the tube 11, the first side plate 21 and the second side plate 22 are fixedly connected to the heat exchange coil 11; one end of the heating pipe section 31 is fixedly connected to the first side plate 21 , and the other end is fixedly connected with the second side plate 22 . In addition, the heat exchange coil 11 is a pipeline through which the refrigerant flows.

In this embodiment, since the defrosting heating device is in contact with the fin 12 by passing through the lower part of the fin 12, so when the defrosting heating device is powered on and starts to work, the heat emitted by it can pass through the contact with it. The fins 12 conduct directly upward. Compared with the current common defrosting heating device installed under the bottom of the evaporator 1 without contact with the fins 12, in the technical solution of the utility model, in addition to using hot air to rise to cause cold and hot air In addition to the natural convection defrosting, the fins 12 in contact with the defrosting heating device can also be used to quickly conduct heat to the top of the evaporator, so as to realize the rapid defrosting of the entire evaporator, and the defrosting efficiency is greatly improved. Shorten the defrosting time, effectively reduce the power consumption of defrosting, and finally reduce the energy consumption of the refrigerator. In addition, for the currently common scheme that the defrosting heating device is arranged below the bottom of the evaporator 1 without contacting the fins 12, since it can only defrost from the bottom and use the natural convection of cold and hot air to slowly conduct heat upwards The defrosting time is long and the heat conduction medium is air, so the heat in the air is easily transferred to the refrigeration chamber through the wall board of the adjacent refrigerator refrigeration chamber, which will cause the refrigeration chamber to be too high and affect the food quality. In the technical solution of the utility model, the heat is mainly conducted through the fins 12, and the defrosting time is short, so the heat transferred to the refrigeration chamber through the air will be greatly reduced, thereby avoiding adverse effects on the refrigeration chamber , which in turn facilitates food storage.

Referring to Fig. 2 and Fig. 4, in this embodiment, specifically, there are two heating pipe sections 31, and the two heating pipe sections 31 are connected into a U-shaped heating pipe 3 through a jumper pipe (not marked), and the U-shaped One end where the two nozzles 321 of the heating tube 3 are located is the first end 32 , and the other end opposite to the first end 32 is the second end 33 . Wherein, the top ends of the two nozzles 321 of the first end 32 are upwardly curved, and after passing through the first side plate 21, electric wires (not shown) are respectively connected to the outer surfaces of the first side plate 21, so that The U-shaped heating tube 3 can be heated by electricity. Of course, this design is not limited thereto. In other embodiments, the specific shape and quantity of the defrosting heating device can be set according to actual needs. Wires are connected to both ends of the board 21 and the second side board 22 .

Referring to Fig. 1, Fig. 2 and Fig. 3, in this embodiment, specifically, the lower part of the fin 12 corresponds to the two heating pipe sections 31 and is provided with two installation through holes 1231 for the two heating pipe sections 31 to pass through, and further Specifically, the lower part of each fin 12 is further provided with an installation through groove 123 communicating with the two installation through holes 1231 , and the installation through groove 123 is used for integrally passing through the two heating pipe sections 31 . Of course, in other embodiments, the two installation through holes 1231 can also be arranged in a non-communicative manner, but during installation, since the defrosting heating device needs to be accurately aligned with the plurality of installation through holes 1231, it is convenient to install. Sex is not as good as this embodiment.

In addition, as shown in FIG. 3 , in this embodiment, further, the edge of the installation through hole 1231 extends away from the fin 12 to form a heat exchange flange 1232 , and the heat exchange flange 1232 is connected to the outer surface of the heating tube section 31 . The tube faces are in face-to-face contact. In this way, on the one hand, the setting of the heat exchange flange 1232 can increase the contact area between the heating pipe section 31 and the fin 12, thereby increasing the heat conduction efficiency, which is beneficial to shorten the defrosting time and reduce energy consumption; on the other hand, by setting The heat exchange flanging 1232 can convert the original line-to-surface contact between the heating pipe section 31 and the fins 12 into surface-to-surface contact, thus effectively avoiding cutting damage to the heating pipe section 31 due to the sharp edge of the installation through hole 1231 situation occurs.

What needs to be specially explained here is that, referring to FIG. 1 and FIG. 3 , in this embodiment, preferably, the fin 12 includes a plurality of long fin units 121 and short fin units 122 arranged in parallel and spaced apart, each of which is long The bottom of the fin unit 121 is provided with two installation through holes 1231 and the installation through groove 123 communicating with the installation through holes 1231. The heating pipe section 31 of the U-shaped heating tube 3 passes through these installation through holes 1231, and is connected with the long fins. The sheet unit 121 is in contact. Compared with the current common evaporator with fins 12 of only one length, in this embodiment, on the one hand, by adding short fin units 122, the evaporation area of the evaporator can be increased, thereby improving the cooling effect; On the one hand, the short fin unit 122 is located on the side of the evaporator away from the U-shaped heating tube 3, so it can effectively avoid that when the short fin unit 122 is close to the U-shaped heating tube 3, the space between the fins 12 is small And it is easy to be completely filled by the ice layer, so that the convection space of cold and hot air is greatly reduced, which eventually leads to the decrease of defrosting efficiency.

Referring to Fig. 2, Fig. 4, Fig. 5 and Fig. 6, in this embodiment, specifically, the lower part of the first side plate 21 is provided with two nozzles 321 corresponding to the first end 32 for one-to-one correspondence between the two nozzles 321. Two fixed first through holes 2111 are provided, and the two first through holes 2111 communicate through a fixed through groove 211 . The fixing slot 211 is used for integrally passing through the two heating tube sections 31 . Of course, in other embodiments, the two first through holes 2111 can also be arranged in a non-communicative manner, but during installation, since the defrosting heating device needs to be accurately aligned with the two first through holes 2111, it is necessary to install The convenience is not as good as this embodiment.

In addition, in this embodiment, in order to further improve the installation convenience of the U-shaped heating tube 3 and the stability of the connection between the U-shaped heating tube 3 and the first side plate 21, one of the edges of the fixed through groove 211 is opposite to one of them. A bendable first limiting piece 2112 is connected to the position of the first through hole 2111 . Before the U-shaped heating tube 3 is installed on the first side plate 21, the first limiting piece 2112 can be bent to be perpendicular to the first side plate 21, and then the U-shaped heating tube 3 is installed on the first side plate 21. Afterwards, the first limiting piece 2112 can be bent back to be located in the fixing through groove 211, so as to limit the vertical displacement of the heating tube section 31 that has been locked into the first through hole 2111.

Referring to FIG. 1 , FIG. 4 and FIG. 6 , in this embodiment, specifically, the lower part of the second side plate 22 corresponds to the second end 33 and is provided with a second through hole 221 for the second end 33 to pass through and fix as a whole. Furthermore, a bendable second limiting piece 2211 is connected to the lower edge of the second through hole 221 at the position between the two heating pipe sections 31. Of course, in other embodiments, the second limiting piece The piece 2211 can also be arranged to extend downward from the upper edge at a position between the two heating pipe sections 31 . Similar to the first limiting piece 2112, before the U-shaped heating tube 3 is installed on the second side plate 22, the second limiting piece 2211 can be bent to be perpendicular to the second side plate 22, and then the U-shaped After the second end 33 of the heating tube 3, that is, the jumper tube passes through the second side plate 22, the second limiting piece 2211 can be bent back to be located in the second through hole 221, so that The jumper tubes of the two side plates 22 serve as a position limiter to prevent the jumper tubes from easily detaching from the second side plate 22 . Of course, in other embodiments, when the second through hole is replaced by two single holes that are not connected to each other, it is also possible to prevent the jumper tube from easily detaching from the second side plate 22, but this arrangement will result in a U-shaped The heating tube 3 needs to pass through the second side plate 22, the plurality of fins 12, and the first side plate 21 from the outer surface of the second side plate 22 one by one in order to complete the installation, especially when the side plate 2 and the evaporation When the device 1 needs to be fixed first, the installation process will be particularly cumbersome and difficult; but in the technical solution of this embodiment, it is only necessary to first pass the U-shaped heating tube 3 through the fins 12, and then install the first side plate 21 The second side plate 22 and the first end 32 and the second end 33 of the U-shaped heating tube 3 can be respectively penetrated and connected correspondingly, so that the whole installation process is very convenient.

The above is only a preferred embodiment of the present utility model, and does not therefore limit the scope of the patent of the present utility model. Under the inventive concept of the present utility model, the equivalent structural transformation made by using the specification of the utility model and the contents of the accompanying drawings, or Direct/indirect application in other related technical fields is included in the patent protection scope of the present utility model.
