4results about How to "Affect cooling efficiency" patented technology

The invention discloses a cooling device for efficient heat dissipation of a gearbox, and relates to the technical field of transmission devices. The radiator fan is rotatably mounted in the radiator main frame and is rigidly connected with the fan motor; one side of the cooling fan is provided with a cooling pipeline which is connected with a temperature control valve, and the other side of the cooling fan is provided with a cooling plate; an air inlet of the radiator is provided with an anti-flocculation net, and an air outlet of the radiator is provided with an air duct which is communicated with the cabin; the heat dissipation plates are of an integral aluminum magnesium alloy structure. The cooling pipeline is a double-layer high-elasticity fiber and steel wire winding rubber pipe; the temperature control valve is of a spring pressure type; the anti-flocculation net comprises an aluminum alloy frame and a diamond net; the surface of the radiator is coated with a graphene-containing coating; the ventilating duct and the exhaust hood are made of military silica gel coating glass fiber cloth; the cooling fan and the like form a penetrating type heat exchange core body; a reinforcing lifting lug is arranged on the main frame; the cooling capacity is guaranteed, the operation stability of the gearbox is improved, and the service life is prolonged.

This utility model discloses a condensing device for an air conditioning refrigeration unit, relating to the field of air conditioning refrigeration technology. It includes a fixed housing with a condenser tube mounted on it. Mounting plates are provided on both sides of the fixed housing, and mounting holes are drilled through the surfaces of both mounting plates. A mounting shell is mounted on the surface of the fixed housing. A heat dissipation mechanism for cooling the condenser tube is provided inside the mounting shell and mounted on the condenser tube. A dustproof mechanism for preventing dust from entering the fixed housing is provided on both the fixed housing and the mounting shell. The dustproof mechanism includes a dustproof mesh shell, which is slidably mounted on the outer wall of the mounting shell. Four studs are fixedly mounted on the surfaces of both the fixed housing and the mounting shell, and the dustproof mesh shell is slidably mounted on the four front studs. This utility model achieves rapid heat dissipation from the condenser tube and prevents dust from affecting its heat dissipation efficiency. It is simple to operate and highly practical.

The utility model relates to the technical field of groove-type plastic-spraying cabling racks, and discloses a dustproof groove-type plastic-spraying cabling rack, which comprises a fixed frame and a cabling groove, knob rods are mounted in vertical plates on two sides of the fixed frame in a threaded manner, and an abutting and clamping plate is mounted at one end of each knob rod. According to the dustproof groove type plastic spraying cabling rack, through cooperative arrangement of a heat dissipation groove, a dustproof net, a fixing frame, a first rotating shaft, a first bevel gear, a brush plate, a first motor, a second bevel gear, a second rotating shaft, a third bevel gear, fan blades, a second motor and a fourth bevel gear, when the dustproof groove type plastic spraying cabling rack is used, the fan blades are driven by the second motor to dissipate heat of a cable in a cabling groove; the controller regularly controls the second motor to suspend, then the first motor is controlled to drive the brush plate to rotate, dust attached to the surface of the dustproof net is brushed off at the same time, then after cleaning is completed, the first motor is stopped, the second motor is started in sequence, and therefore the situation that the dustproof net is blocked, and the heat dissipation efficiency of the wiring groove is affected is effectively prevented.

The application discloses a kind of direct cooling wind power generator self-cleaning type cooling device, including base, the side wall of the base is fixedly connected with installation box, the side wall of the side of installation box away from base is fixedly connected with protection box, the side wall of the side of protection box is equipped with connecting frame, the both sides of the side wall of protection box are fixedly connected with air inlet box, the side wall of the side of air inlet box away from protection box is fixedly connected with cooling box, cooling pipe is equipped in cooling box.The application solves the phenomenon that air dust enters the inside of wind power generator in air-water cooling, by setting cooling box, cleaning groove, filter screen, air inlet box and other structures, the air entering the protection box is blocked by filter screen, cooling pipe and air inlet box, to avoid dust from entering the protection box to affect the use of generator, while cooperating with the cooling cycle of cooling pipe in cooling box and air inlet and suction, the cooling efficiency of generator set can be improved.
