Embodiment Construction
[0028] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0029] In order to better understand the present invention, the cooling device provided in the existing water jet propulsion device is briefly described here, figure 1 It is a structural schematic diagram of a serpentine tube radiator provided by an embodiment of the present invention, as figure 1 As shown, a serpentine pipe 11 is provided in the hydraulic pump oil tank 10, and hydraulic oil is stored in the hydraulic pump oil tank 10. When the hydraulic oil is cooled, water is injected into one end of the serpentine pipe 11, and the water flows to the serpentine The pipe 11 flows out from the other end, and the water will cool the hydraulic oil in the hydraulic pump oil tank 10 when flowing through the serpentine pipe 11 .

The invention discloses a radiator and a hydraulic jet propulsion device and belongs to the hydraulic jet propulsion field. The radiator comprises a cooling oil tank which is provided on an outer side wall of an inlet end of an inlet pipe; the cooling oil tank comprises side plates, a cover plate, an oil inlet and an oil outlet. Through the installation of the cooling oil tank on the outer side wall of the inlet end of the inlet pipe and the installation of an oil inlet and an oil outlet on the cooling oil tank, the cooling oil tank is connected between a hydraulic cylinder and a hydraulic pump oil tank so that when a hydraulic control system works, high temperature hydraulic oil flows from the hydraulic cylinder to the cooling oil tank; plenty of water continuously passes through the inlet pipe so that when the high temperature hydraulic oil flows through the cooling oil tank, the heat is taken away by the water in the inlet pipe and therefore the high temperature hydraulic oil is cooled; the water in the inlet pipe is directly utilized for cooling so that there is no need to provide cooling water source which saves production cost; meanwhile, the water flow in the inlet pipe is large so that the heat dissipation effect is better.
Description
technical field [0001] The invention relates to the field of water jet propulsion, in particular to a radiator and a water jet propulsion device. Background technique [0002] The water jet propulsion device is a kind of ship propeller, which provides the thrust of the ship's movement through the reaction force generated by the jet of water. An inverted bucket scoop is arranged at the water nozzle of the water jet propulsion device, and its function is to change the direction of the jet water flow. The reverse bucket scoop is controlled by the hydraulic control system to realize the forward and reverse functions. The hydraulic control system will generate a lot of heat during frequent work, so the hydraulic control system needs to be cooled. [0003] In the existing water-jet propulsion device, a set of serpentine tube radiator is installed in the oil tank of the hydraulic pump. The radiator has two external interfaces, one of which is connected to the cooling water source,...
