Abstract
The utility model is a cooling tower with the function of anti-freeze and the cooling copper tube in the tower will not be damaged even in environment of extremely low temperature. The utility model comprise a box body whose lower part is water collection groove corresponding with the upper space of the water collection groove; the side of the box body opens up wide, the water collection groove is connected with the spray pump, the upper wall of the box body is provided with a cooling blower, a spray device and a cooling copper tube are arranged between the cooling blower and the water collection groove sequentially from the top down. The utility model is characterized in that: an inlet valve and an outlet valve are positioned between the corresponding entrance and the exit of each cooling copper tube, a backflow tube which is provided with a pump, a temperature censor and a heater connects the inlet of the inlet valve and the inlet of the outlet valve, the temperature censor and the heater are electrically connected with the controller, the two ends of the backflow tube are provided with a control valve.
Description
(1) technical field
The utility model relates to cooling device, is specially the cooling tower with antifreeze function.
(2) background technology
Its structure of existing cooling tower comprises casing, the bottom of described casing is a water leg, the upper space position of corresponding described water leg, the side of described casing is opened wide, described water leg connects the spray water pump, the roof of described casing is provided with cooling blower, is disposed with spray equipment, cooling copper tube from top to bottom between described cooling blower and the described water leg.Cooling water in the cooling copper tube can cool off the higher equipment of required precision, and the cooling water in the water leg can cool off common equipment, thereby can realize different refrigerating functions at the equipment of different required precisions.The shortcoming of this cooling tower is exactly: when stopping work, just have ponding in the bend of cooling tube, and ponding can't be discharged, under the lower condition of temperature, as under the temperature of subzero tens degree in the north, will freeze in the cooling tube, cooling tube is very easily by bursting by freezing.
(3) summary of the invention
At the weak point of existing cooling tower, the utility model provides a kind of cooling tower with antifreeze function, even environment temperature is very low, its inner cooling copper tube can not be damaged by frost yet.
Its technical scheme is such: it comprises casing, the bottom of described casing is a water leg, the upper space position of corresponding described water leg, the side of described casing is opened wide, described water leg connects the spray water pump, the roof of described casing is provided with cooling blower, be disposed with spray equipment from top to bottom between described cooling blower and the described water leg, cooling copper tube, it is characterized in that: be respectively arranged with water intaking valve and outlet valve between the entrance and exit of corresponding every cooling copper tube, between the delivery port of water intaking valve and outlet valve water inlet, be connected with return duct, in the described return duct pump is set, temperature sensor, heater, described temperature sensor, heater and controller electricly connect, and the two ends of return duct are respectively arranged with control valve.
The utility model adopts after the said structure; when shutting down like this; when the temperature in the copper pipe is low; temperature sensor transfers temperature signal to the signal of telecommunication and passes to controller, controller control heater and pump work, thus guarantee circulating of water temperature in the copper pipe and water; copper pipe just can not be damaged by frost yet like this; thereby avoided existing cooling tower, cooling copper tube was exposed to low temperature environment fully when it was shut down, the shortcoming that the water freezing in the pipe causes copper pipe to be damaged by frost.
