As shown in Figures 1 to 6, the refrigeration equipment of this embodiment includes a cabinet 1, an air duct assembly 2 and a refrigeration system, wherein a refrigeration cavity 101 for storing items is formed in the cabinet 1. Normally, the cabinet 1 includes an outer shell and an inner liner, a foaming layer is formed between the outer shell and the inner liner, and a refrigeration cavity 101 is formed in the inner liner. The refrigeration system usually includes a compressor, a condenser, a throttling device, and an evaporator 3 that are connected together. The cold energy released by the evaporator 3 is exchanged with the air in the refrigeration cavity 101 to achieve refrigeration. 3 is set in the air duct assembly 2. The air duct assembly 2 has an air outlet 201 and a return air outlet 202. The air in the refrigeration cavity 101 enters the air duct assembly 2 and exchanges heat with the evaporator 3 to form cold air and then enters the refrigeration cavity 101 for refrigeration.

Among them, due to the sinking effect of the cold air, in the actual cooling process, after the cold air formed by the heat exchange enters the refrigeration cavity 101, the cold air will sink to the bottom of the refrigeration cavity 101, causing the refrigeration cavity 101 to fail. The large temperature difference between the upper and lower parts causes uneven temperature distribution. In order to solve the above-mentioned problems, a heat conduction component is provided in the refrigeration cavity 101, and the heat conduction component is arranged in the refrigeration cavity 101 along the height direction.

Specifically, after the refrigeration cavity 101 is provided with heat conduction components along the height direction, in the actual cooling process, the cold air output from the air outlet 201 sinks to the bottom of the refrigeration cavity 101 due to gravity, and the heat conduction of the heat conduction components It can transfer the cold energy at the bottom of the refrigeration cavity 101 to the upper part of the refrigeration cavity 101. In this way, the upper part of the refrigeration cavity 101 is cooled by a heat transfer component to ensure the uniformity of temperature distribution in the refrigeration cavity 101 . In addition, since the refrigeration cavity 101 is equipped with a heat conduction component, in the process of outputting cold air through the air outlet 201, the conduction function of the heat conduction component can be used to utilize the distribution form of the heat conduction component in the height direction during the cooling process. The cooling capacity is more evenly transmitted to the various parts of the refrigeration cavity 101, so as to reduce the uneven distribution of the cooling capacity caused by the direction of the wind, and it is more conducive to improving the overall cooling effect.

By arranging heat conduction parts in the refrigeration cavity of the cabinet, the heat conduction parts are distributed along the height direction as a whole. During the refrigeration process, the temperature of the upper part of the refrigeration cavity will be higher than the temperature of the lower part due to the rising of the hot air under the cold wind, and the heat conduction is used The components conduct cold energy, and the heat conduction components can absorb cold energy from the bottom of the refrigeration cavity and transfer it upward to release the cold energy, thereby making the upper and lower temperature distribution of the refrigerating cavity more uniform, so as to improve the cooling effect and optimize the user experience.

Further, there are multiple forms for the specific manifestation of the heat conduction component, so as to realize the transfer of the cold energy in the upper and lower height directions. For example, the heat conduction component includes: the heat conduction vertical plate 4, which is arranged in the refrigeration cavity along the height direction.体101中。 Body 101. Specifically, the thermal conductive vertical plate 4 is made of a material with good thermal conductivity. For materials such as aluminum or copper, the heat-conducting vertical plate 4 can be attached to the back or both side walls of the refrigeration cavity 101. The conduction effect of the heat-conducting vertical plate 4 in the height direction enables the cooling capacity to be evenly distributed along the height direction, effectively Reduce the impact of uneven distribution of cooling capacity on storage to optimize the cooling effect.

Wherein, according to need, in order to increase the coverage area of the heat conduction component to further improve the uniformity of the cooling capacity, as shown in FIG. 7, the heat conduction component further includes: a thermally conductive top plate 41 (not shown), and the thermally conductive top plate 41 is disposed on the refrigeration cavity 101 At the top of the, the cold conducted by the heat conducting vertical plate 4 is conducted to the heat conducting top plate 41 in a thermal conduction manner, so as to realize the thermal conduction connection between the heat conducting top plate 41 and the heat conducting vertical plate 4. Specifically, the heat-conducting top plate 41 is installed on the top of the refrigeration cavity 101. During the process of outputting cold air through the air outlet 201, the heat-conducting top plate 41 absorbs the cold energy and quickly conducts and distributes it to the top of the refrigeration cavity 101. The cooling capacity can use the principle of cold air sinking from the top to more evenly cool the lateral area of the refrigeration cavity 101. Since the heat conducting top plate 41 is thermally connected to the heat conducting vertical plate 4, when the bottom of the refrigeration cavity 101 collects more cold energy On the one hand, the heat-conducting vertical plate 4 conducts cooling in the longitudinal height direction and releases the cold for uniform cooling. At the same time, the heat conducted by the heat-conducting vertical plate 4 is further transferred to the heat-conducting top plate 41, and the heat-conducting top plate 41 is used on the top. Cool off.

In addition, the heat-conducting vertical plate 4 and the heat-conducting top plate 41 can also be an integral structure, for example, the heat-conducting vertical plate 4 and the heat-conducting top plate 41 formed by bending an aluminum plate into an integrated structure. Preferably, in order to improve the heat transfer efficiency, the heat-conducting component can also be Heat pipes are arranged on the vertical plate 4 and/or the heat-conducting top plate 41, and the express heat transfer capability of the heat pipe is used to realize that the cold at the bottom of the refrigeration cavity 101 is more quickly distributed on the heat-conducting vertical plate 4 and/or the heat-conducting top plate 41, and the heat pipe The end or a certain part of it is arranged at the bottom of the refrigeration cavity 101 to ensure that the heat pipe can directly absorb the cold at the bottom of the refrigeration cavity 101.

Still further, the air duct assembly 2 includes: an air duct cover 21, which is arranged in the refrigeration cavity 101 and close to the back of the refrigeration cavity 101, and a circulating air is formed between the air duct cover 21 and the back of the refrigeration cavity 101 Channel, the air channel cover 21 is provided with an air outlet 201 and a return air outlet 202; the fan 22 is arranged in the circulating air channel; wherein the evaporator 3 is also arranged in the circulating air channel. Under the action of the fan 22, the air in the refrigeration cavity 101 enters the circulating air passage through the air return port 202, exchanges heat with the evaporator 3 to form cold air, and is output from the air outlet 201 to the refrigeration cavity 101.

Specifically, the cold air output from the air outlet 201 is blown upwards, so that on the one hand, it can ensure that the cold air can be effectively delivered to the top area of the refrigeration cavity 101, and on the other hand, the bottom area of the refrigeration cavity 101 is realized by sinking the cold air. In this way, in the cold air output process, the uniform distribution of the cold energy can be realized at the initial stage. Since the air outlet 201 is located at the bottom of the refrigeration cavity 101 and close to the back, the output from the air outlet 201 After the cold air flows upward, the cold air moves to the top of the refrigeration cavity 101 and flows downward along the front area of the refrigeration cavity 101 under the action of gravity, so as to realize the circulation of cold air in the refrigeration cavity 101 and ensure uniform cooling capacity. distributed.

Perform refrigeration. In this way, in actual use, when the fan 22 starts running, the heat-conducting vertical plate 4 can be cooled by the cold air conveyed in the circulating air channel and the cold air output from the air outlet 201, so as to quickly cool the cooling cavity 101 When the fan 22 stops rotating, the remaining cold energy of the evaporator 3 itself is used to cool the heat conducting vertical plate 4 by means of heat radiation. In this way, the bottom of the heat-conducting vertical plate 4 can transfer the cold accumulated at the bottom of the refrigeration cavity 101 upward, and at the same time, the cold released by the evaporator 3 is also absorbed and utilized by the heat-conducting vertical plate 4 and further releases the cold into the refrigeration cavity 101. In this way, on the one hand, uniform cooling can be ensured, and on the other hand, energy consumption can be reduced.

Furthermore, in order to effectively increase the heat exchange area and heat exchange time between the air in the refrigeration cavity 101 and the evaporator 3, the evaporator 3 has a plate structure, and the evaporator 3 is longitudinally arranged in the circulating air channel along the height direction to evaporate The evaporator 3 is sandwiched between the back of the refrigeration cavity 101 and the air duct cover 21.
