Embodiment Construction
[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0023] Cooling circulation system provided by the present invention, such as figure 1 As shown, it includes the first refrigeration cycle unit 1 , the second refrigeration cycle unit 2 , ... until the Nth refrigeration cycle unit, and the bypass cooling unit 3 . All refrigeration units and bypass cooling units perform liquid circulation and cooling to a common oil tank 4 . Each refrigeration cycle unit refrigerates various types of cooling equipment, and the pressure design and flow design of the circulation pipeline are related to the type of cooling equipment and cooling capacity requirements. The flow and temperature of the refrigerating cycle unit, and the flow and temperature of the bypass cooling unit are controlled by a controller 5 (see figure 2 ) to be controlled.
[0024] Taking the first refrigeration cycle unit 1 as an example, the int...

The invention relates to a cooling circulation system of liquid cooling equipment and a cooling method. The system comprises a plurality of refrigerating cycle units arranged in parallel and a bypass cooling unit, which share an oil tank and a controller, wherein each of the refrigerating cycle units mainly comprises a motor pump group, a control valve bank, the oil tank and an accessory; the revolving speed of the motor is controlled through variable power or voltage signals provided by the controller; a filter and an electromagnetic directional valve are connected in series on an oil delivery pipeline; the oil liquid is fed to a cooling request device through a reversing valve; an oil return pipeline is connected with the oil tank through the reversing valve; a flowmeter, a temperature sensor, and a pressure sensor are arranged on the oil delivery pipeline; another temperature sensor is arranged on the oil return pipeline. According to the cooling circulation system disclosed by the invention, the bypass cooling unit is used for cooling the oil tank bypass. The invention further provides a novel hydraulic circulating system which controls the revolving speed of the motor to control the flow, and further provides a novel cooling circulation method, namely bypass cooling. Therefore, the size of the equipment is reduced, and the equipment cost is lowered.
Description
technical field [0001] The invention belongs to the technical field of liquid cooling, and in particular relates to a cooling circulation system of liquid cooling equipment and a cooling method for the circulation system. Background technique [0002] Liquid cooling is a common cooling method for equipment. The replacement of some large equipment requires higher and higher cooling requirements. For example, with the development of my country's aviation and national defense, the functions and performance of cooling equipment have been improved to varying degrees, and the heat generation of internal electronic equipment has gradually increased. During routine inspection, maintenance, or commissioning of cooling equipment, external cooling protection equipment is required to cool internal electronic equipment, which is called liquid cooling equipment in the industry. Usually, with the development of different types of cooling equipment, the external liquid cooling equipment of...
