It should be noted that the air-cooled heat dissipation flow type semiconductor refrigeration system of the present invention may be a vertical structure or a horizontal structure, and the vertical structure will be described in detail in the detailed description of the present invention.

As a preferred embodiment of the present invention, as shown in fig. 1, the liquid driving device 5 includes a liquid flow pipeline 51 and a pumping device 52 disposed outside the storage container 1, the storage container 1 is provided with a liquid inlet 11 and a liquid outlet 12, the liquid inlet 11 and the liquid outlet 12 are connected through the liquid flow pipeline 51, the liquid flow pipeline 51 and the inner cavity of the storage container 1 form a closed flow liquid path, and the pumping device 52 is disposed on the flow liquid path. The pumping device 52 drives the drinking liquid in the storage container 1 to be pumped from the liquid outlet 12 through the liquid flow pipeline 51 and then to flow from the liquid inlet 11, so that the drinking liquid in the storage container 1 is in an external circulation flow state, and the heat convection motion of the drinking liquid in the storage container 1 is promoted. The liquid inlet 11 and the liquid outlet 12 of the storage container 1 may be formed by communicating the liquid inlet 11 and the liquid outlets 12 through a liquid flow pipeline 51 in a one-to-one correspondence manner, or communicating one liquid inlet 11 with a plurality of liquid outlets 12 through a shunt pipeline, or communicating a plurality of liquid inlets 11 to one liquid outlet 12 through the liquid flow pipeline 51. The arrangement of the pumping device 52 on the flowing liquid path may be that the pumping device 52 is arranged on a pipeline of the liquid flowing pipeline 51, or that an inlet of the pumping device 52 is directly connected with the liquid outlet 12, and an outlet of the pumping device 52 is connected with the liquid flowing pipeline 51 and communicated with the liquid inlet 11.

Further, the local turbulence creating structure includes: the liquid inlet 11 of the storage container 1 is arranged at the upper part of the storage container 1, and the liquid outlet 12 is arranged at the lower part of the storage container 1, so that local turbulence of liquid in the storage container 1 is formed by utilizing the height difference impact of the liquid inlet 11 and the liquid outlet 12 in the working process, the heat convection motion of the drinking liquid in the storage container 1 is promoted, and the drinking liquid is favorably and uniformly cooled. Thus, during the cooling operation, the drinking liquid is pumped out of the liquid outlet 12 in the lower part of the storage container 1 by the pumping device 52 and is fed from the liquid inlet 11 in the upper part of the storage container 1 into the upper part of the storage container 1 via the liquid flow line 51, so that the drinking liquid in the lower part of the storage container 1 is continuously pumped out, and the newly cooled drinking liquid in the upper part of the storage container 1 is continuously filled, and is continuously circulated, and the liquid flow path 7 formed by the liquid driving device 5 and the storage container 1 is a convection movement path of forced circulation outside the container. Since the drinking liquid in the lower part of the storage container 1 is continuously pumped out, the drinking liquid in the storage container 1 needs to be continuously filled in the lower part, so that the drinking liquid in the storage container 1 integrally has a tendency of continuously moving from top to bottom, and the movement is different from a natural heat convection movement track, namely a forced heat convection movement which is designed and relatively accurately controls the movement track of the drinking liquid. That is to say, in the technical scheme of the present invention, the movement track of the drinking liquid in the storage container 1 is relatively accurately controlled, so that the movement of the drinking liquid is compliant and forms a forced heat convection movement, and forced convection heat exchange of the drinking liquid is formed and promoted, thereby effectively improving the refrigeration efficiency, rapidly reducing the temperature of the drinking liquid, significantly improving the refrigeration efficiency, simultaneously making the temperature of the drinking liquid uniform, avoiding the phenomena of low bottom temperature and high top temperature, and effectively improving the use experience of users.

As a preferred embodiment of the present invention, as shown in fig. 2, a flow guide plate 6 is further covered on the outside of one side of the cold guide member 4 exposed to the inner cavity of the storage container 1, a flow guide channel is formed between the flow guide plate 6 and the cold guide member 4, and the liquid flow pipeline 51 is led into the storage container 1 to reach the flow guide channel. The drinking liquid in the storage container 1 is directly communicated into the flow guide channel through the liquid flow pipeline 51 to be in contact with the cold guide piece 4 for refrigeration, the flowing speed of the drinking liquid near the cold guide piece 4 is increased, the heat exchange coefficient between the drinking liquid and the fins is improved, and the refrigeration efficiency is improved. Wherein, guide plate 6 can be vertical setting, inserts the end of intaking of liquid flow line 51 to the top of leading cold spare 4 through inlet 11, will drink liquid direct switch-on after the outside flow to the water conservancy diversion passageway with lead cold spare 4 contact and cool off, utilize the action of gravity of drinking liquid self, make and drink liquid and flow to water conservancy diversion passageway bottom back from the top of leading cold spare 4 and flow out, increase and drink liquid and lead the contact time of cold spare 4, improve refrigeration efficiency. In order to improve the structural stability of the liquid flow line 51 in the storage container 1, the top of the baffle 6 may be provided with a through hole through which the liquid flow line 51 passes.

As a preferred embodiment of the present invention, as shown in fig. 3, the liquid driving device 5 is disposed on the inner wall of the storage container 1, and the suction port 53 and the pump outlet 54 of the liquid driving device 5 are both located in the inner cavity of the storage container 1, wherein the suction port 53 faces the cold guide member 4, and the pump outlet 54 has a pumping direction which is at an angle to the pumping direction of the suction port 53, so as to drive the drinking liquid around the cold guide member 4 to move away from the cold guide member 4 during operation, and to enable the drinking liquid in other areas in the storage container 1 to be guided to move towards the cold guide member 4. The liquid driving apparatus 5 may be arranged such that only one liquid driving apparatus 5 is disposed on the inner wall of the storage container 1, or a plurality of liquid driving apparatuses 5 are distributed on a single or a plurality of inner walls of the storage container 1.

Preferably, the cold conductor 4 is located on the refrigeration side wall 1a of the storage container 1, and the liquid driving device 5 is arranged on the drainage side wall 1b opposite to the refrigeration side wall 1a, and directly draws away or impacts the newly cooled drinking liquid near the inner surface of the cold conductor 4, so as to promote the thermal convection movement of the drinking liquid in the storage container 1. Furthermore, the liquid driving device 5 can be a centrifugal pump, so that the use safety and the service life of the liquid driving device 5 are improved.

Specifically, referring to the structure shown in fig. 3, in this structural form, the liquid driving device 5 adopts a centrifugal pump to drive the drinking liquid to move in the storage container 1, the cold guide member 4 is positioned on the refrigeration side wall 1a of the storage container 1 and is arranged on the drainage side wall 1b opposite to the refrigeration side wall 1a, and the pump outlet 54 faces upward (generally, the pumping direction of the pump outlet 54 and the suction direction of the suction port 53 have an angle of 0-90 degrees, and the invention is arranged to be perpendicular to each other in fig. 3). This arrangement makes it possible for the liquid drive 5 to drive the drinking liquid around the cold guide 4 in the storage container 1 in a direction away from the cold guide, while at the same time causing the drinking liquid in other regions of the storage container 1 to be guided in a direction towards the cold guide 4. In this way, during the cooling operation, the drinking liquid around the suction opening 53 is continuously sucked in by the liquid drive 5 and pumped out of the pump outlet 54, so that the newly cooled drinking liquid around the cold-conducting part 4 is continuously moved in the direction away from the cold-conducting part 4, and the uncooled drinking liquid in the region away from the cold-conducting part 4 is continuously filled, and thus continuously circulated, a forced circulation movement of the drinking liquid is formed. Since the drinking liquid near the cold guide member 4 is continuously pumped away, the drinking liquid in other areas in the storage container 1 needs to continuously move towards the cold guide member 4 to fill the area near the cold guide member 4, and the movement track of the drinking liquid can be controlled relatively accurately. Because the liquid near the cold-conducting piece 4 is continuously pumped out, the liquid in other areas in the liquid storage container 1 is continuously guided to move towards the cold-conducting piece 4 to fill the area near the cold-conducting piece 4, so that the liquid in the liquid storage container 1 integrally presents two internally circulating liquid flow paths 7 shown in fig. 2 at two sides of the suction opening 53 of the liquid driving device 5, and forced heat convection movement for relatively accurately controlling the movement track of the liquid is formed. Meanwhile, as the liquid driving device 5 continuously drives the liquid to move, local turbulence is formed around the suction port 53 and the pump outlet 54 of the liquid driving device 5 due to liquid impact, the cold energy diffusion and the liquid mixing are further enhanced, the refrigeration efficiency is improved, and the phenomenon of uneven liquid cooling effect in the liquid storage container is avoided.

Furthermore, although pump outlet 54 of liquid drive device 5 is shown facing upwards in fig. 3, it could also face downwards as a variant, which does not correspond to the formation of liquid flow path 7. In order to make the two liquid flow paths 7 more smooth, the pump outlet 54 of the liquid driving device 5 may have two pump outlets 54 facing upwards and two pump outlets 54 facing downwards, so that the two liquid flow paths 7 circulating inside the upper and lower chambers are formed more smoothly, and the local turbulence formed at the same time is more dispersed, which is beneficial to improving the cooling efficiency and the temperature uniformity.

It should be noted that the liquid driving device 5 of the present invention is not limited to the above two embodiments, and for example, an impeller may be provided in the storage container 1 to control the thermal convection motion and local turbulence of the drinking liquid by stirring.

The cold guide 4 may be detachably and hermetically connected to the storage container 1, or may be formed integrally with the storage container 1. For example, a cold guide mounting opening is formed on the side wall of the storage container 1, mounting holes matched with each other are formed on the periphery of the cold guide mounting opening and the cold guide plate 41, the cold guide 4 is mounted on the side wall of the storage container 1 to close the cold guide mounting opening and is hermetically mounted through a sealing ring, and the detachable mounting form is favorable for cleaning and maintenance of storage container internal parts such as the storage container 1 and the cold guide 4.

One side of the heat sink 31 is in contact with the hot end of the semiconductor refrigeration chip 2, and the other side is connected with the cooling air driving device 32, and the cooling air driving device 32 can take away the heat of the heat sink 31, so as to achieve the purpose of heat dissipation. Specifically, the heat sink 31 may be heat-dissipating aluminum or heat-dissipating copper, and the cooling air driving device 32 may be a fan.

Further, a heat-absorbing liquid mist diffusing device 33 is provided on the cooling wind path between the cooling wind driving device 32 and the heat sink 31, and the heat-absorbing liquid mist diffusing device 33 is provided on the cooling wind path at a position before the cooling wind enters the heat sink 31 or on a section passing through the heat sink 31. For example, a grid net is arranged between the cooling air driving device 32 and the heat sink 31, a plurality of heat absorption liquid mist spreading devices 33 are arranged on the grid net, the spreading direction of the liquid mist is consistent with the air supply direction of the cooling air driving device 32, when the cooling air driving device 32 works, the heat absorption liquid mist spreading devices 33 are opened, the liquid mist is sprayed by using spray heads of the heat absorption liquid mist spreading devices 33, the liquid mist can be blown to the surface of the heat sink 31 by cooling air, the heat of the heat sink 31 is carried away by evaporation of the liquid mist, and the heat energy generated by the hot end of the semiconductor refrigeration chip 2 is conducted faster and has higher heat dissipation efficiency, so that the temperature difference between the hot end and the cold end of the semiconductor refrigeration chip 2 is smaller, and the refrigeration performance of the semiconductor refrigeration chip 2 is improved. The heat-absorbing liquid mist diffusing device 33 is not limited to the illustrated structure, and may be disposed on the heat sink 31, and the heat-absorbing liquid mist diffusing device 33 may directly spray the liquid mist onto the heat sink 31 to achieve the effect of absorbing heat and reducing temperature.
