The invention relates to the technical field of heat dissipation equipment, and discloses heat dissipation equipment for electromechanical equipment. The heat dissipation equipment comprises a heat dissipation box, the left side surface of the heat dissipation box is fixedly connected with a 
water storage tank, and the inner wall of the 
water storage tank is fixedly provided with a first heat 
insulation layer. Cold water in the 
water storage tank can enter the circulating 
water pipe by starting the water pump and finally enters the 
water storage tank again, in the whole circulating process, the cold water flows in the circulating 
water pipe all the time, heat in the heat dissipation box can be absorbed, heat in the equipment is absorbed away under the action of the first 
air pump, and under the action of the second 
air pump, the 
cold air in the inner cavity of the heat dissipation box is blown into the equipment, the 
cold air is input into the equipment while internal heat of the equipment is absorbed, the equipment can be timely and rapidly cooled, and more cold water can flow in the inner cavity of the heat dissipation box through the multi-section overlapping design of the circulating 
water pipe in the inner cavity of the heat dissipation box, so that the heat 
absorption efficiency can be improved.
