[0036] The airflow output by the ventilation hood 204 can be discharged into the interior of the heat exchange base 1 and discharged from the gaps in the heat dissipation plate 102 .

[0037] Specifically, the heat exchange base 1 further includes: a cover plate 104 connected to the opening of the liquid storage bin 103, and a plurality of air holes 105 are provided on the cover plate 104;

[0038] The heat exchange pump 5 is arranged on the cover plate 104 .

[0039] Specifically, the airflow baffle 205 divides the interlayer space between the ventilation hood 204 and the cooling barrel 202 into a plurality of airflow cavities 207, and the air outlets of the airflow cavities 207 are connected to the interior of the heat exchange base 1. Figure 4 As shown, the airflow in the ventilation hood 204 is discharged from the outlets of the plurality of airflow cavities 207 into the inner circle of the liquid storage bin 103 , and further, the airflow passes through the gaps between the plurality of heat dissipation plates 102 and is discharged to the outside.

[0040] The air path of the ventilation hood 204 cools the cooling barrel 202 and the heat exchange base 1 in turn, forming a gradient heat dissipation.

[0041] Specifically, a plurality of support rods are provided at the bottom of the cooling barrel 202 .

[0042] Specifically, the heat exchanger 4 includes: a heat exchange tube 403, a heat exchange partition 405 is arranged inside the heat exchange tube 403, the heat exchange partition 405 can divide the space inside the heat exchange tube 403 into a plurality of chambers, and a flow port 406 is provided between the heat exchange partition 405 and the inner wall of the heat exchange tube 403, and the chambers can be connected through the flow port 406.

[0043] The heat exchange tube 403 is provided with an end cover 401 , and the end cover 401 is provided with a liquid exchange interface 402 , which is communicated with the chamber.

[0044] In this embodiment, the heat exchange baffle 405 can divide the interior of the heat exchange tube 403 into two chambers, both of which are connected to the liquid exchange interface 402, and the chambers are connected through the flow port 406. Figure 2 shown.

[0045] A plurality of heat exchange fins 404 are disposed on the outer wall of the heat exchange tube 403. The heat exchange fins 404 increase the contact area between the heat exchanger 4 and the material, and the heat exchange baffle 405 inside the heat exchange tube 403 can extend the flow path of the coolant, and the combined effect of the two improves the heat exchange efficiency.

[0046] Specifically, the tank cover 3 is provided with a material interface 301 and a heat exchange interface 302, and the heat exchange tube 403 is inserted into the heat exchange interface 302.

[0048] The specific use principle of the utility model is as follows:

[0049] After the heat exchange pump 5 is started, the coolant in the liquid storage tank 103 of the heat exchange base 1 is pumped into the liquid exchange interface 402 of the heat exchanger 4. The coolant flows through the chambers separated by the heat exchange baffle 405 in the heat exchange tube 403 in sequence, and flows between the chambers through the flow port 406. In this process, the heat exchange fins 404 on the outer wall of the heat exchange tube 403 exchange heat with the material in the tank, and the coolant after absorbing the heat of the material returns to the liquid storage tank 103 through the pipeline, forming a closed-loop liquid circuit circulation.

[0050] The cooling barrel 202 is sealed and filled with coolant. The liquid storage tank 201 conducts heat to the cooling barrel 202 through the tank wall. The heat sink 203 increases the contact area between the liquid storage tank 201 and the coolant in the cooling barrel 202, thereby enhancing the heat transfer effect. The external air source is injected into the ventilation hood 204 through the air inlet 206. The airflow is evenly distributed to a plurality of airflow cavities 207 by the airflow baffle 205. The airflow contacts the outer wall of the cooling barrel 202, thereby enhancing the heat dissipation of the cooling barrel 202.

[0051] Furthermore, the airflow discharged from the airflow cavity 207 enters the interior of the heat exchange base 1, passes through the gap of the heat sink 102, performs secondary heat dissipation on the coolant in the liquid storage tank 103, and is finally discharged from the gap of the heat sink 102, thereby achieving coordinated heat dissipation of the air path and the liquid path.
