The views shown in fig. 5 and 6 are in the same direction. Fig. 7 is a schematic view of another angle of an assembly structure of the fixing bracket 3 with the radiator fan 32 and the condenser 31 in the refrigerator according to some embodiments of the present invention; fig. 8 is a schematic view of another angle of a fixing bracket 3 in a refrigerator according to some embodiments of the present invention; and the orientation of the views shown in fig. 7 and 8 coincide. Fig. 9 is an exploded view of a fixing bracket and an assembly structure of a heat dissipation fan and a condenser of a refrigerator according to some embodiments of the present invention.

The fixed support 3, the heat radiation fan 32 and the condenser 31 form a pre-assembled integrated piece to form an air duct structure for passing through heat radiation air flow, so that the air flow completely flows through the condenser 31, the heat radiation efficiency is improved, the structure is more compact, and the assembly process is simplified.

The fixing bracket 3 is disposed in the transverse middle of the heat sink bin 12, and divides the heat sink bin 12 into a first heat dissipation chamber 121 and a second heat dissipation chamber 122 along the transverse direction of the box body. One side of the fixed support 3 facing the first heat dissipation cavity is provided with a fan fixing structure, and one side of the fixed support 3 facing the second heat dissipation cavity is provided with a condenser fixing structure. I.e. the side of the fan fixing structure facing the compressor 2 and the side of the condenser fixing structure facing the evaporating dish 4. And the fixed bracket 3 is disposed in the front-rear direction.

The heat dissipation fan 32 is mounted on the fan fixing structure for promoting the formation of heat dissipation airflow which enters from the outside of the case and is blown through the first heat dissipation chamber 121 and the second heat dissipation chamber 122 and then is discharged out of the case. The condenser 31 is mounted on a condenser mounting structure and is cooled by a heat dissipating airflow. The air current loops through compressor 2, condenser 31 and evaporating dish 4, dispels the heat to each part in proper order, has improved the radiating efficiency.

The fixed support 3 is respectively provided with a fan fixing structure and a condenser fixing structure on two sides so as to be used for assembling the cooling fan 32 and the condenser 31 to form an integrated air duct structure, so that the space occupied by the cooling fan 32 and the condenser 31 is smaller. The arrangement structure of the components in the heat radiator bin is more compact, a larger arrangement space is provided for the compressor 2 and the evaporating dish 4, and the heat radiation efficiency is favorably improved. Compared with the prior art in which the condenser is disposed above the evaporating dish 4, the structure of the present embodiment reduces the dimension of the heat sink bin 12 in the height direction.

The fixing bracket 3 includes a bracket main body 33 and a wind deflector 34. The holder main body 33 has a square tubular shape and extends in the lateral direction of the case 1, that is, in the left-right direction. The cylindrical shape of the bracket main body is used for allowing the heat dissipation airflow to pass through. A wind shield 34 extends from the front end of the bracket main body 33 for blocking the front regions of the first and second

heat dissipation chambers

121 and 122 to prevent the return air of the heat dissipation air, and only allows the air to blow through the cylinder of the bracket main body 33.

The fan fixing mechanism includes a plurality of fan fixing claws 331 of the holder main body 33 protruding toward the first heat dissipation chamber 121 to clamp the casing of the heat dissipation fan 32 with the fan fixing claws 331, and a part of the casing of the heat dissipation fan 32 is embedded in the holder main body.

The inner section of the cylinder of the bracket body 33 facing the first heat dissipation chamber 121 is adapted to the shape of the casing of the heat dissipation fan 32, so as to prevent the heat dissipation fan 32 from being installed incorrectly. That is, the portion of the bracket main body 33 that is engaged with the heat dissipation fan 32 by providing a structure such as a rib and a groove. If the heat dissipation fan 32 is not assembled in the pre-designed direction, it cannot be fitted due to structural interference, thereby preventing assembly errors. The fan fitting structure limits the installation space of the heat dissipation fan 32 to be approximately in a direction cylindrical space, and the heat dissipation fan 32 has an error insertion prevention structure. The fan fixing clamping jaw 331 fixes the heat dissipation fan 32, and if the heat dissipation fan 32 needs to be detached, the fan fixing clamping jaw 331 is shifted to detach the fan 32, so that the fan is very convenient to mount and detach.

The fan fixing claws 331 may be configured and positioned according to the structure of the casing of the heat dissipation fan 32, and may be provided on the peripheral wall of the bracket main body 33 to project in the direction of the compressor 2, for example. The cooling fan 32 is assembled with the support main body 33 through a clamping structure, so that the assembly and disassembly are convenient, the working procedures are reduced, and the assembly efficiency is improved.

Damping foam (not shown) is arranged between the shell of the heat radiation fan 32 and the inner cylinder wall of the bracket main body 33. The vibration generated when the cooling fan 32 rotates can be reduced by the damping foam, and the sealing performance between the casing of the cooling fan 32 and the bracket main body 33 can be improved. The axial flow fan is preferably used as the heat radiation fan 32, the axial direction extends in the left-right direction, and the air supply direction is from the first heat radiation cavity 121 to the second heat radiation cavity 122 after passing through the bracket main body 33.

One or more wire winding buckles 332 are arranged on the periphery of one side of the bracket main body 33 facing the first heat dissipation cavity 121 and used for winding the overlong cable of the heat dissipation fan 32. The winding buckle protrudes from the peripheral wall of the holder main body 33 for winding. The cooling fan 32 is too long and placed in the cooling fan compartment 12, which may cause messy components and reduced reliability during long-term use. The present embodiment utilizes the wire winding buckle to solve the problem of the arrangement of the above-mentioned cables. After the cooling fan 32 is installed to the bracket main body 33, the cable of the cooling fan 32 is wound by a circle or several circles through the winding buckle 332 so as to avoid the overlong of the fan cable, and finally the cable is guided through the winding buckle 332 and finally connected to the terminal in the socket at the top of the cooling fan bin 12, so that the cable of the cooling fan 32 is prevented from being burnt out when the pipeline of the condenser 31 is welded. The winding mode of the fan cable is convenient and fast, and the safety risk which may occur actually is avoided.

The condenser fixing structure includes a plurality of condenser fixing claws 337 protruding toward the second heat dissipation chamber 122 from the bracket body 33 to catch the condenser 31 with the condenser fixing claws 337. The condenser 31 may preferably be a micro-channel condenser, thereby saving the space occupied by the condenser 31 and facilitating the cooperation with the holder main body 33. Gaps among micro channels of the micro-channel condenser are consistent with the direction of heat dissipation airflow, and all the heat dissipation airflow needs to pass through the condenser 31, so that the heat exchange efficiency is improved.

The configuration and position of the condenser fixing jaw 337 may be set according to the structure of the condenser 31. For example, the condenser fixing claws 337 may protrude at upper and lower portions of the bracket main body 33. At least part of the condenser 31 is embedded inside the holder body 33 to facilitate the air flow. That is, the shape of the condenser 31 is matched with the cylinder inner interface of the bracket main body 33 facing the second heat dissipation chamber 122, so that the efficiency of heat dissipation airflow passing through the condenser 31 is improved, and the structure is more compact. The condenser 31 is assembled with the bracket main body 33 through a clamping structure, so that the assembly and disassembly are convenient, the working procedures are reduced, and the assembly efficiency is improved. The condenser 31 is integrally embedded into the bracket main body 33 and is positioned inside the air duct, so that heat dissipation airflow is fully utilized, and the space of the evaporating dish 4 can be prevented from being occupied.

In assembling, the condenser 31, the heat dissipation fan 32 and the fixing bracket 3 may be assembled in advance to form an integrated pre-assembly, and then the pre-assembly is integrally installed in the housing 1.

The fixing bracket 3 may also be provided with mounting catches 334 and fixing screw posts 335. Wherein the mounting buckle 334 is arranged at the bottom of the fixing bracket 3 and is used for being clamped with the bottom plate of the heat sink bin 12. The fixing screw column 335 is disposed at the rear of the fixing bracket 3, and is used for fixing with the rear wall plate of the heat sink bin 12 by screws. The mounting buckle 334 and the fixing screw column 335 can enable the fixing support 3 to be reliably assembled with the box body 1, and the mounting and dismounting are gradually changed, so that the mounting and dismounting processes are reduced.

The top of the fixing bracket 3 is further opened with a guide groove 336 for passing through a refrigeration pipeline for connecting the compressor 2 and the condenser 31. The fixing bracket 3 may further have a rib and groove structure as required for the circuit and the pipeline communicating the first heat dissipation chamber 121 and the second heat dissipation chamber 122 to pass through.

A blocking member may be further provided in the cylinder of the holder main body 33 so that the cooling fan 32 is spaced apart from the condenser 31.

Based on the foregoing description, it can be understood by those skilled in the art that by sequentially arranging the compressor 2, the fixing bracket 3 and the evaporating dish 4 in the right and left direction of the cabinet 1 in the heat sink bin 12, the height of the heat sink bin 12 is effectively reduced compared to the prior art in which a condenser is arranged in the evaporating dish, thereby making more space for the storage compartment 11 of the refrigerator, and thus making the storage compartment 11 have a larger storage space.

Further, through on installing condenser 31 and cooling fan 32 fixed bolster 3, support main part 33 is square tube-shape both sides and assembles through the joint structure with cooling fan 32 and condenser 31 respectively, and the air that flows into in cooling fan storehouse 12 all can flow through condenser 31, cools off condenser 31, has guaranteed condenser 31's cooling effect.

So far, the technical solution of the present invention has been described in connection with the foregoing embodiments, but it is easily understood by those skilled in the art that the scope of the present invention is not limited to these specific embodiments. Without departing from the technical principle of the present invention, a person skilled in the art may split and combine the technical solutions in the above embodiments, and may make equivalent changes or substitutions for related technical features, and any changes, equivalents, improvements, etc. made within the technical concept and/or technical principle of the present invention will fall within the protection scope of the present invention.
