[0014] Optionally, two ends of the heat dissipation copper tube extend out of the base and are respectively fixed to the water inlet flange and the water outlet flange.

[0015] Optionally, the lower end of the heat conducting plate extends into the base and is connected to the heat dissipating copper tube.

[0016] Optionally, a connection block is fixed to the outer side of the shell, and a control unit is installed on the outer side of the connection block.

[0017] Optionally, the wiring board is provided with wiring electrodes, the shell is provided with wires electrically connected to the wiring board, and the honeycomb layer and the heat conducting plate are provided with wire holes for the wires to pass through.

[0018] Compared with the prior art, the utility model has at least the following beneficial effects:
