Description
Technical Field
[0001] The utility model belongs to the technical field of heat dissipation structures, and in particular relates to a heat dissipation structure of an outdoor unit of a central air conditioner. Background Art

[0014] The beneficial effect of this improvement is that the overflow pipe is connected to a hose used for drainage, and when there is too much condensed water in the condensed water collection box, it can overflow through the overflow pipe.
[0015] For the control of this device:
[0016] As a further improvement of the above technical solution: a water level sensor is provided inside the condensate collection box, and the water level sensor is electrically connected to the controller.
[0017] The beneficial effect of this improvement is that the water level sensor is used to detect the water level height in the condensate collection box. When the water level inside the condensate collection box is low, the controller will not control the electric control valve and the micro boost pump to open.
[0018] To drain the condensate collection tank:
[0019] As a further improvement of the above technical solution: a drainage bolt is provided at the bottom of the condensate collection box.
[0020] The beneficial effect of this improvement is that when all the condensed water in the condensed water collection box needs to be drained, the water in the condensed water collection box can be drained by simply unscrewing the drain bolt.
