[0026] Both sides of the lower end of the electrophoresis tank body 1 have inner concave parts 5 , and the side view projection shape of the heat dissipation cavity 2 is consistent with the contour shape of the lower end surface of the electrophoresis tank body 1 .

[0028] Among them, Figure 3 As shown, mounting pages 13 are provided on both sides of the electrophoresis tank body 1, and connecting pages 22 are provided on both sides of the heat dissipation cavity 2. When the heat dissipation cavity 2 is installed under the electrophoresis tank body 1, the mounting page plates 13 and the connecting page plates 22 are connected and installed with each other by bolts, so that the upper end surface of the heat dissipation cavity 2 is tightly installed and contacted with the bottom of the electrophoresis tank body 1; a pad 21 for moving the electrophoresis tank body 1 is provided at the inner recess 5 of the electrophoresis tank body 1.

[0032] In some embodiments, Figure 3 As shown, multiple groups of partitions 23 can be provided, and multiple groups of partitions 23 are each provided with multiple plate holes. The partitions 23 can be made of metal materials. The partitions 23 divide the interior of the heat dissipation cavity 2 into different heat dissipation channels, forming multiple fast airflows flowing through both sides of the partitions 23, which can improve the heat dissipation efficiency inside the heat dissipation cavity 2.
[0033] In some embodiments, Figure 3 As shown, sealing plates 3 are provided on both sides of the electrophoresis tank body 1 to block the outside of the air inlet through hole 201 .

[0035] It should be noted that, by providing a rotatable sealing plate 3 and providing a filtering hole inside the air inlet hole 201, the sealing plate 3 can be rotated to adjust the size of the air inlet channel of the air inlet hole 201 according to actual needs of heat dissipation.
[0036] In some embodiments, Figure 3 As shown, rotating parts 6 are provided on both sides of the lower end of the heat dissipation cavity 2, and the contour of the rotating part 6 is the same as the contour of the inner recess 5. The exhaust mechanism 4 is arranged on the top of the rotating part 6, and the interior of the exhaust mechanism 4 is connected with the interior of the heat dissipation cavity 2.
[0037] In some embodiments, Figure 3 As shown, the exhaust mechanism 4 includes a vertically mounted cylinder and an exhaust fan 41 mounted inside the cylinder, and the upper end of the cylinder extends into the heat dissipation cavity 2.
[0038] In addition, when the electrophoresis apparatus needs to be kept warm, by closing the air inlet holes 201 and the exhaust fan 41, the air between the electrophoresis tank body 1 and the heat dissipation cavity 2 can be used as a heat preservation layer outside the electrophoresis tank body 1, thereby reducing heat loss.
