Detailed Description

The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the utility model.

Embodiments of the utility model: as shown in fig. 4-17, an air duct module is disclosed, which comprises a housing 31, an air inlet 33 and an air outlet 34 arranged on the housing 31, an air guide piece 37 arranged in the housing 31, and a fan assembly;

the casing 31 has a base 316 and a cover plate 317 matched with the base 316, the air guide 37 has an air guide body 371 clamped and positioned between the base 316 and the cover plate 317 and a communication hole 372 arranged on the air guide body 371, the air guide body 371 divides the casing 31 into an air inlet cavity communicated with the air inlet 33 and an air outlet cavity communicated with the air outlet 34, and the communication hole 372 is communicated with the air inlet cavity and the air outlet cavity; the fan assembly is used for transferring the cold sucked by the air inlet 33 to the air outlet 34.

In this embodiment, the air duct is actually formed by arranging the air guide 37 in the housing 31, and in order to better realize the transmission of the cold energy in the air duct, the air guide 37 is a foam member arranged between the cover plate 317 and the base 316.

The air guide piece 37 is arranged to be a foam piece, so that the air guide piece 37 can be attached to the base 316 and the cover plate 317 more tightly on the basis of reducing cost and weight, the foam piece can bear certain deformation, and the foam piece can be attached to the cover plate 317 or the base 316 only in a pressing mode.

In the prior art, the air deflector is generally integrally injection molded on the base 316, and one end of the air deflector far away from the base 316 is attached to the cover plate 317 to form an air channel between the air deflector, the cover plate 317 and the base 316. One end of the air deflector attached to the cover plate 317 in the prior art is difficult to be completely attached to the cover plate 317, so that a gap exists between the air deflector and the cover plate 317, and when cold is transferred in the air duct, the cold can leak out of the gap, thereby influencing the efficiency of cold transfer in the air duct.

According to the embodiment, the air guide piece 37 made of foam materials is clamped between the cover plate 317 and the base 316, so that two opposite sides of the air guide piece 37 can be attached to the cover plate 317 and the base 316, gaps are avoided between the air guide piece 37 and the cover plate 317 or between the air guide piece 37 and the base 316, leakage of cold energy cannot occur when the cold energy is transmitted in the air duct, and the cold energy can be more efficiently discharged from the air inlet and then the air outlet along the extending direction of the air duct.

The fan assembly in this embodiment includes a turbo fan 32, where the turbo fan 32 has an axial air inlet side 321 and a radial air outlet side 322, and the axial air inlet side 321 and the radial air outlet side 322 are perpendicular to each other. The air duct 35 includes an air inlet duct 351 disposed between the axial air inlet side 321 and the air inlet 33, and an air outlet duct 352 disposed between the radial air outlet side 322 and the air outlet 34.

The air inlet air duct 351 is located in the air inlet cavity or the air inlet air duct 351 directly forms the air inlet air duct 351, and the air outlet air duct 352 is located in the air outlet cavity or the air outlet cavity directly forms the air outlet air duct 352.

In this embodiment, the fan assembly further has a volute 36 disposed on the base 316, the turbine fan 32 is disposed in the volute 36, the volute 36 has a volute air inlet 361 opposite to the axial air inlet side 321, a volute air outlet 362 opposite to the radial air outlet side 322, and a volute cavity communicating the volute air inlet 361 and the volute air outlet 362, the turbine fan 32 is disposed in the volute cavity, the air inlet 351 is formed between the volute air inlet 361 and the air inlet 33, and the air outlet 352 is formed between the volute air outlet 362 and the air outlet 34.

As shown in fig. 13, in this embodiment, for the sake of convenience in mounting and fixing the fan assembly, the turbine fan 32 is fixed on the base 316, and the volute 36 is covered outside the turbine fan 32 and is mounted and fixed on the base 316. The base 316 is provided with a volute locating plate adapted to the volute 36, and the volute 36 is buckled on the volute locating plate.

Because the front side in the opening direction of the volute air inlet 361 needs to be provided with a gap between the front side direction of the volute air inlet 361 and the cover plate 317, in order to avoid the overall thickness of the casing 31 being larger, the base 316 is provided with an outwardly protruding fan mounting portion, the fan mounting portion is provided with a fan mounting groove arranged inwards, the opening of the fan mounting groove faces the cover plate 317, the arrangement of the mounting groove actually provides an avoidance, and the outwardly protruding fan mounting portion is increased only at the mounting position of the fan, so that the thickness of the whole casing 31 is prevented from being increased under the premise of meeting the fan mounting condition.

It will be appreciated that in another embodiment, a fan mounting portion protruding outwards may be provided on the cover plate 317 and at a position of the scroll fan 32, and a fan mounting groove provided toward the base opening may be provided on an inner side of the fan mounting portion.

The volute 36 is disposed at the position of the communicating hole 372, the volute air outlet 362 is opposite to the position of the communicating hole 372, the volute air inlet 361 is directly exposed to the air inlet cavity,

because the turbo fan 32 is used as a power source for transferring cold, the air outlet cavity and the air inlet cavity are relatively arranged at the upper side and the lower side of the communication hole 372 in the vertical direction for realizing high-efficiency transmission of cold.

In order to reduce the thickness of the entire housing 31, in this embodiment, the side of the volute 36 facing the base 316 is not provided with a cover plate, but directly uses the base 316, so that the base 316 forms a side wall enclosing a volute cavity, that is, the volute 36 has a volute body, an open slot is formed on the side of the volute body facing the base 316, the side of the volute body where the open slot is disposed abuts against the base 316, and the base 316 is blocked at the open position of the open slot, so that the volute cavity is formed between the volute body and the base 316.

As shown in fig. 13, the scroll casing 36 needs to be formed into the inner wall of the scroll casing cavity by the base 316, and the scroll casing 36 needs to be generally tightly attached to the base 316, but in the actual manufacturing process, a gap exists between the scroll casing 36 and the base 316, and the existence of the gap can cause the cold to leak out from the side of the air duct, so that the release efficiency of the cold of the air outlet 34 is reduced; and if a complete fit of the volute 36 to the base 316 is required, the difficulty of the machining process is high, and the cost is increased.

As shown in fig. 12 and 15-17, in order to reduce the lateral exposure of the cold energy during the transmission in the air duct, the air guide 37 further has a volute positioning portion 373 provided on the air guide body 371; the volute positioning portion 373 is fixedly attached to the base 316 and has a positioning groove 374 (shown in fig. 17) that is adapted to the volute 36, and the positioning groove 374 has an opening that is exposed toward the communication hole 372, that is, the positioning groove 374 communicates with the communication hole 372.

The volute 36 is positioned in the positioning groove 374 and between the volute positioning portion 373 and the base 316, and a positioning portion through hole 375 is provided on the volute positioning portion 373 opposite to the position of the volute air inlet 361; the positioning portion through hole 375 is used for exposing the volute air inlet 361 outwards, an air guiding gap is formed between the volute positioning portion 373 and the cover plate 317, the positioning portion through hole 375 is exposed towards the air guiding gap, and it can be understood that the air guiding gap is located in the air inlet cavity.

In this embodiment, the volute positioning portion 373 attached to the base 316 is provided outside the volute 36, so that the problem of leakage of cold energy caused by a gap between the volute 36 and the base 316 can be effectively solved.

In this embodiment, the volute positioning portion 373 and the air guiding body 371 are integrally formed and made of foam material, however, in other embodiments, a material with a certain deformation such as rubber may be used, so that the air guiding member 37 can be tightly attached to the cover plate 317 and the base 316 when clamped between the base 316 and the cover plate 317.

In addition, since the storage space 10 is disposed with the opening upwards, and the upper side of the whole storage space 10 is opened, the cooling capacity at the opening position of the storage space 10 is seriously dissipated outwards, and the difference between the cooling capacity at the position of the storage space 10 close to the opening and the cooling capacity of the storage space 10 close to the bottom is caused, which is specifically shown that the cooling capacity is more sufficient in the area close to the bottom of the storage space 10, and the cooling capacity is relatively insufficient at the opening position of the storage space 10.
