[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention draws the internal hot air into the ventilation mechanism by setting a first fan. At the same time, the second fan draws the external air into the ventilation mechanism. The hot air and the cold air meet at the intersection, which reduces the gas temperature. The guide plate guides the airflow, so that the cold air enters from the cold air inlet to the bottom of the cabinet and cools down from bottom to top, and the hot air is discharged from the hot air outlet. The above structure can effectively cool the interior of the temperature control cabinet.

[0022] 2. The placement plate is used to place equipment and devices. The through-holes in the plate body allow gas to move from bottom to top, so that the gas can cool the placement plate and the placed devices when it moves. The first cold liquid pipe transports cold liquid, which is transported from the first delivery pipe to the diversion pipe and diverted to different rectangular flow channel cavities, so that the placed devices can be cooled and dissipated by contacting the placement plate. When the cold air passes through the through-holes in the plate body, the liquid in the rectangular flow channel cavity contacts the cold air through its heat transfer surface, so that the gradually heated liquid is cooled by heat exchange. The shape of the rectangular flow channel cavity perfectly adapts to the through-holes in the plate body, making the heat transfer surface larger and more It is easy to be exposed to cold air, and the cavity extension mouth is just between the rectangular flow channel cavities, so that the liquid will enter the next rectangular flow channel cavity only after filling the rectangular flow channel cavity. After the inside is completely filled, the liquid coverage area is increased, so that it has a better cooling and heat dissipation effect on the devices placed above. The liquid finally reaches the first heat exchange tube for heat exchange. After the heat exchange is completed, it is sent back to the first cold liquid tube through the circulation tube for cooling operation. During the heat exchange, the second cold liquid tube and the second heat exchange tube of the other group can connect the cooling process for secondary cooling, making the entire cooling process more comprehensive and can be used in conjunction with wind cooling.

[0044] Working principle: When in use, the first fan 10 draws the internal hot air into the ventilation mechanism 16. At the same time, the second fan 25 draws the external air into the ventilation mechanism 16. The hot air and the cold air intersect at the intersection 27, which reduces the gas temperature. The guide plate 26 guides the airflow, so that the cold air enters the bottom of the cabinet from the cold air inlet 28 and cools down from bottom to top, and the hot air is discharged from the hot air outlet 29. The above structure can effectively cool down the interior of the temperature control cabinet. The placement plate 20 is used to place equipment and devices. The through hole 23 of the plate body plays the role of supplying gas to move from bottom to top, so that the gas can cool the placement plate 20 and the placed devices when it moves. The first cold liquid pipe 30 plays the role of transporting cold liquid. The cold liquid is transported from the first delivery pipe 31 to the diversion pipe 32 and diverted to different rectangular flow channel cavities 33, so that the placed devices can be cooled by contact. The plate 20 is placed and cooled and dissipates heat. When the cold air passes through the through-holes 23 of the plate body, the heat transfer surface 24 of the liquid in the rectangular flow channel cavity 33 contacts the cold air, so that the gradually heated liquid is heat-exchanged and cooled. The shape of the rectangular flow channel cavity 33 perfectly adapts to the through-holes 23 of the plate body, so that the heat transfer surface 24 is larger and easier to contact with the cold air. The cavity extension mouth 34 is just between the rectangular flow channel cavities 33, so that the liquid will enter the next rectangular flow channel cavity 33 only after filling the rectangular flow channel cavity 33. After the inside is completely filled, its liquid coverage area is increased, so that it has better cooling and heat dissipation effect on the devices placed above. The liquid finally reaches the first heat exchange tube 36 for heat exchange. After the heat exchange is completed, it is sent back to the first cold liquid pipe 30 through the circulation pipe 37 for cooling operation. While it is exchanging heat, the second cold liquid pipe 38 and the second heat exchange pipe 39 of the other group can connect the cooling process for secondary cooling.
