The utility model discloses a cooling device with a water pump and a fan coaxially driven. The cooling device comprises a double-shaft motor and a water pump head. By arranging the heat dissipation mechanism, the double-shaft motor is started to facilitate cooling liquid to enter the annular micro-channel through the liquid inlet pipe, meanwhile, the fan impeller rotates to blow out cold air dissipated from the surface of the annular micro-channel to achieve the cooling effect, and the problems that on one hand, the heat dissipation fan and the water pump are arranged in a split mode, the occupied space is large, and the cooling effect is poor are solved. Particularly, compact integration is difficult to realize in miniaturized equipment, so that lightweight development of the equipment is seriously restricted; on the other hand, the overall energy consumption of the system is obviously increased due to independent driving of double motors, in addition, long-distance pipeline connection not only causes pressure loss of cooling liquid and reduction of heat exchange efficiency, but also brings higher leakage risk due to increase of sealing joints, and meanwhile, a distributed structure enables daily maintenance and overhaul processes to be complicated, so that the service life of the system is prolonged. The operation and maintenance cost is further improved, and the effects of improving the heat exchange efficiency and reducing the energy consumption are achieved.

The utility model discloses a liquid cooling heat pipe radiator, include: radiator main part, including liquid cooling board, heat pipe, radiating fin, heat dissipation frame and fan, the heat pipe is located the bottom of liquid cooling board, the radiating fin is located the outside of heat pipe, the middle part of liquid cooling board is connected with liquid delivery tube, and the both ends of liquid delivery tube are connected with water inlet pipe and water outlet pipe respectively, the middle part of water outlet pipe is provided with the pump body, cleaning assembly sets up in the middle part of heat dissipation frame and fan, including the support frame of fixed heat dissipation frame upper end, can solve in the long -term operation process of fan, external dust will be attached to the surface of radiating fin with airflow, forms the dense dust layer, thereby makes dust accumulation to hinder the direct contact of radiating fin and air, reduces the heat exchange efficiency, then, liquid cooling system is the problem that needs to improve fan speed or prolongs the working time for the compensation heat dissipation efficiency reduction, and then aggravates dust adsorption and increases the energy consumption.
