Description

Technical Field

[0001] The utility model relates to the technical field of generator sets, in particular to an air-cooled and water-cooled dual-cycle generator set. Background Technique

[0002] A generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy. It consists of a power system, a control system, a sound insulation system, a shock absorption system, and an exhaust system. It is driven by a water turbine, a steam turbine, a diesel engine, or other power machinery, and converts the energy generated by the flow of water, air flow, fuel combustion, or nuclear fission into mechanical energy and transmits it to the generator, and then the generator converts it into electrical energy and outputs it for use on electrical equipment.

[0003] In the Chinese patent with the publication number CN219492398U, an air-cooled and water-cooled dual-cycle diesel generator set is disclosed. It controls the air flow to quickly pass through the machine box through the air-cooling device, quickly taking away a large amount of heat, thereby achieving the effect of cooling. The water-cooling device quickly circulates the water flow through the surrounding water pipes in the box, taking away a large amount of heat, and then dissipating heat through an external cooling water tank, thereby achieving the effect of rapid cooling. The air-cooled and water-cooled dual-cycle cooling system can more efficiently dissipate heat from the diesel power generation device, so that the diesel generator set has higher working efficiency and long-term stable operation.

[0004] This device uses a relatively large number of fans to achieve the actions of synchronous air intake and air supply on the machine box, which makes the air flow rapidly flow in the machine box. However, both the water-cooling device and the air-cooling device use the method of exhausting air near the machine box to achieve cooling, and the heat surrounds the machine box and does not dissipate. It will circulate in the water-cooling device and the machine box under the action of multiple fans, thereby reducing the efficiency of the water-cooling device in preparing cold water and the heat dissipation efficiency of the generator set in the machine box. For this reason, we provide an air-cooled and water-cooled dual-cycle generator set to solve the above problems. Content of the Utility Model
