[0028] In the embodiments shown in the drawings, the indications of direction, such as up, down, left, right, front and back, are used to explain the structure and movement of various elements of the present application, and are not absolute but relative. These indications are appropriate when the elements are in the positions shown in the drawings. If the positions of the elements change, the indications of direction will also change accordingly.

[0029] Referring to Figure 1 and Figure 2 , the refrigeration air duct structure provided by an embodiment of the present application mainly comprises a flow dividing member 1, a refrigeration structure 2 and a fan 3. The flow dividing member 1 is provided with a hot gas inlet 113, a flow guide groove 114, an air inlet groove 122 and a cold gas outlet 115. The flow guide groove 114 is in communication with the hot gas inlet 113 and the air inlet groove 122 respectively, and is used to guide the hot gas input from the hot gas inlet 113 to the air inlet groove 122. The cold gas outlet 115 is not in communication with the hot gas inlet 113, the flow guide groove 114 and the air inlet groove 122. The refrigeration structure 2 is used to cool the hot gas and form cold gas, and the refrigeration structure 2 is arranged opposite to the cold gas outlet 115. The fan 3 is arranged opposite to the air inlet groove 122, and the fan 3 is used to guide the hot gas in the air inlet groove 122 to the refrigeration structure 2, and make the cold gas formed by cooling via the refrigeration structure 2 flow out from the cold gas outlet 115.

[0030] In the refrigeration air duct structure, the hot gas flows into the flow guide groove 114 from the hot gas inlet 113, and under the guidance of the flow guide groove 114, enters the air inlet groove 122, and the fan 3 arranged opposite to the air inlet groove 122 starts to work, to generate air flow driving force, to guide the hot gas flow in the air inlet groove 122 to the refrigeration structure 2, and then the refrigeration structure 2 cools the hot gas flowing to it, and the cold air formed by cooling of the refrigeration structure 2 flows out from the cold air outlet 115 under the guidance of the air flow driving force generated by the fan 3. Since the cold air outlet 115 is not communicated with the hot gas inlet 113, the flow guide groove 114 and the air inlet groove 122, the effective separation of the hot and cold air flow can be realized, so that the refrigeration air duct structure can effectively cool the hot air, and ensure that the transmission between the hot air and the cold air does not interfere with each other. Since the hot gas inlet 113, the flow guide groove 114, the air inlet groove 122 and the cold air outlet 115 are integrated on the flow distribution piece 1, the channel planning of the hot air and the cold air is realized by reasonable design, the use of additional components is reduced, and the complexity of the overall structure is reduced.

[0031] In a specific embodiment, the flow distribution piece 1 includes a first part 11 and a second part 12 connected together, the hot gas inlet 113, the flow guide groove 114 and the cold air outlet 115 are arranged on the first part 11, and the air inlet groove 122 is arranged on the second part 12. The second part 12, the fan 3 and the refrigeration structure 2 are arranged in sequence, the first part 11 is located on one side of the fan 3 and the refrigeration structure 2, and is arranged at an inclined angle with the stacking direction of the second part 12, the fan 3 and the refrigeration structure 2.

[0032] The second part 12, the fan 3 and the refrigeration structure 2 are arranged in sequence, and the first part 11 is arranged at an inclined angle with the stacking direction of the second part 12, the fan 3 and the refrigeration structure 2. This layout can make full use of space, so that the overall structure of the refrigeration air duct structure is compact and reasonable, the space utilization is improved, and the first part 11 is arranged at an inclined angle, which can make the hot gas naturally transition from the flow guide groove 114 to the air inlet groove 122 of the second part 12, improving the flowability of the air flow.

[0033] In a specific embodiment, the flow guide groove 114 includes a main groove section 1141 and two sub-groove sections 1142 in communication. The main groove section 1141 is in communication with the hot gas inlet 113, and the two sub-groove sections 1142 are arranged side by side and spaced apart. The two sub-groove sections 1142 are respectively in communication with the gas inlet groove 122, and the cold gas outlet 115 is located between the two sub-groove sections 1142. The hot gas first enters the main groove section 1141 of the flow guide groove 114 from the hot gas inlet 113 on the flow distribution member 1, and then flows to the sub-groove sections 1142. Since the two sub-groove sections 1142 are arranged side by side and spaced apart, the hot gas is divided into two streams at the connection between the main groove section 1141 and the sub-groove sections 1142, and then enters the two sub-groove sections 1142, and further enters the gas inlet groove 122. This flow distribution design can make the hot gas more evenly distributed, which helps to maintain the stability of the airflow in the entire refrigeration air duct structure. Through the reasonable layout between the hot gas inlet 113, the main groove section 1141, the sub-groove sections 1142, the gas inlet groove 122, and the cold gas outlet 115, the entire refrigeration air duct structure is more compact and reasonable.

[0034] Please refer to Figures 2 to 3 In the above embodiment in which the two sub-groove sections 1142 are arranged side by side and spaced apart, the two sub-groove sections 1142 are respectively in communication with the gas inlet groove 122, and the cold gas outlet 115 is located between the two sub-groove sections 1142. The cold gas outlet 115 includes a gas passing opening 1151 and a gas outlet opening 1152 in communication. The first part 11 includes a first bottom plate 111 and two first partition plates 112.

The second part 12 includes a second bottom plate 121. The gas inlet 123 is arranged on the second bottom plate 121. The second bottom plate 121 is connected to the first bottom plate 111 in a circular arc transition.

[0035] Specifically, since the two first partition plates 112 are connected at an angle on the side close to the hot gas inlet 113, the hot gas entering from the hot gas inlet 113 is naturally guided and divided into the two sub-groove sections 1142 formed between the two first partition plates 112 and the first bottom plate 111. Through the design of the first bottom plate 111, the first partition plate 112, and the second bottom plate 121, a specific and feasible structure is provided for the flow distribution member 1 having two sub-groove sections 1142 and the cold gas outlet 115 located between the two sub-groove sections 1142. Through the reasonable layout and connection mode between the components, the refrigeration function is realized while the occupied space of the air duct structure is further reduced, which is conducive to the miniaturization and integration of the refrigeration system.

[0036] Please refer to Figure 2 And Figure 4 In the specific embodiment, the refrigeration structure 2 comprises the refrigeration fin 21, the heat conduction block 22 and the semiconductor refrigeration fin 23 which are sequentially stacked, the refrigeration fin 21 is stacked with the fan 3 and is arranged opposite to the cold air outlet 115, thereby forming an effective refrigeration conduction path.

[0037] Please refer to Figures 1 to 4 In the specific embodiment, the refrigeration structure 2 comprises the frame 24 which is connected with the second part 12 and forms the air outlet channel 1153 which is communicated with the cold air outlet 115 between the second part 12, the refrigeration fin 21, the heat conduction block 22 and the semiconductor refrigeration fin 23 are all arranged in the frame 24, and the refrigeration fin 21 is communicated with the cold air outlet 115 through the air outlet channel 1153.

[0038] The refrigeration fin 21, the heat conduction block 22 and the semiconductor refrigeration fin 23 are all arranged in the frame 24, the frame 24 plays an integrated and protective role, and the air outlet channel 1153 formed between the frame 24 and the second part 12 provides an orderly channel for the flow of the cold air, so that the cold air can flow more concentratedly and smoothly to the cold air outlet 115.

[0039] In the embodiment, the inner wall of the frame 24 is filled with the foam between the heat conduction block 22 and the frame 24, the foam can effectively prevent the heat transfer between the heat conduction block 22 and the frame 24, so as to improve the refrigeration transfer efficiency between the heat conduction block 22 and the refrigeration fin 21.

[0040] In the specific embodiment, the second part 12 is provided with the frame positioning column 124 and the fan positioning column 125 on the side opposite to the air inlet groove 122, the frame 24 is provided with the frame positioning hole 241 matched with the frame positioning column 124, the fan 3 is provided with the fan positioning hole 31 matched with the fan positioning column 125, and the frame positioning column 124 and the fan positioning column 125 are respectively inserted into the frame positioning hole 241 and the fan positioning hole 31. The cooperation of the frame positioning column 124 and the frame positioning hole 241 and the cooperation of the fan positioning column 125 and the fan positioning hole 31 provide accurate positioning reference for the installation and cooperation of the frame 24, the fan 3 and the flow divider 1, which is relatively simple and intuitive in operation.

When the semiconductor refrigeration fin 23 is powered on, the side close to the heat conduction block 22 absorbs heat and conducts the heat to the refrigeration heat dissipation fin 21 through the heat conduction block 22, while the side of the semiconductor refrigeration fin 23 away from the heat conduction block 22 generates heat. The hot-end heat dissipation fin 25 is in contact with the hot side of the semiconductor refrigeration fin 23 to absorb heat. After the heat dissipation fan 4 is started, the heat on the hot-end heat dissipation fin 25 is taken away by convection and dissipated to the external environment, thereby ensuring the refrigeration efficiency of the semiconductor refrigeration fin 23.
