Abstract
A high-voltage frequency converter evaporation cooling system operation maintenance structure belongs to the technical field of high-voltage frequency converter cooling system maintenance. Comprises a breather pipe (1), an air bag (2), a storage tank (3) and a cooling liquid connecting pipe (4); the cooling liquid connecting pipe (4) is connected with the storage tank body 3, the air bag (2) is connected with the vent pipe (1), and the air bag (1) is arranged in the inner cavity of the storage tank body. The advantage lies in, the mode that causes gasbag deformation through the inside and outside pressure differential of gasbag realizes the injection of cooling medium and discharges, and the operation is high-efficient, convenient, also can realize the drainage and irrigation of working medium through the inflater.
Description
Technical Field
The utility model belongs to the technical field of high-voltage inverter cooling system maintains, especially, a high-voltage inverter evaporation cooling system operation maintenance structure is provided.
Background
The evaporative cooling technology is a novel efficient cooling technology which utilizes high-insulation low-boiling-point organic working media to cool heating components in a phase change heat exchange mode. The organic working medium is used for replacing air of the traditional cooling technology as a cooling medium, self-circulation can be realized without other equipment, and the device is more energy-saving, more environment-friendly and more reliable. When the high-voltage inverter evaporative cooling system is overhauled, a cooling working medium in the cooling device needs to be discharged, and the cooling working medium is filled back into the device after the overhaul is finished. The existing maintenance method is manually completed by utilizing gravity through a container and a funnel, and is time-consuming, labor-consuming, low in working efficiency and easy to consume working media. The patent provides a convenient and efficient operation and maintenance method suitable for a high-voltage variable-frequency evaporative cooling system.
Disclosure of Invention
An object of the utility model is to provide a high-voltage inverter evaporation cooling system operation maintenance structure, the cooling medium can be convenient in cooling device, discharge fast and the purpose of pouring into when realizing overhauing. The maintenance method is convenient and quick to operate; the cooling liquid is convenient to manage, and the loss of the cooling liquid can be effectively controlled.
The utility model comprises a breather pipe 1, an air bag 2, a storage tank 3 and a cooling liquid connecting pipe 4. The cooling liquid connecting pipe 4 is connected with the storage tank 3, the air bag 2 is connected with the vent pipe 1, and the air bag is arranged in the inner cavity of the storage tank body. The rapid transfer and discharge of the cooling medium are realized by the deformation of the air bag 2 caused by the pressure difference between the inside and the outside of the air bag 2. The method comprises the following specific steps:
1. preparation before use: the inflating device is connected with the vent pipe 1, inflates the air bag 2 of the maintenance device, discharges the gas in the inner cavity of the storage tank 3 as much as possible, and keeps the gas in the tank in an emptying state.
2. Collecting cooling liquid: carry out sealing connection with cooling device tapping hole with the coolant liquid connecting pipe 4 of overhauing the device, discharge the coolant liquid into and overhaul the container, available air exhaust device connects breather pipe 1 this moment, evenly bleeds to gasbag 2, accelerates the discharge of coolant liquid.
3. And (3) filling back the cooling liquid: after the cooling device is overhauled, a cooling liquid connecting pipe 4 of the overhauling device is hermetically connected with a liquid injection port of the cooling device; the aerating device is connected with the breather pipe 1, the air is inflated into the air bag 2 of the maintenance device, and the cooling liquid is discharged and injected into the cooling device.
The utility model has the advantages that:
1. the atmospheric pressure difference inside and outside the air bag is utilized to accelerate the discharge and injection of the cooling liquid, and the air bag cooling device has the advantages of being simple in operation, saving in time, high in working efficiency and the like.
2. The cooling liquid of the cooling device directly flows into the maintenance device, so that the storage and management are convenient, and the loss of the cooling liquid is less.
