Detailed Description
The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings:
as shown in fig. 1, a shipborne multi-medium cooling system is composed of a liquid storage tank 1, a cooling water unit 2, a water-cooling heat exchange unit 3, an oil-cooling heat exchange unit 4, a liquid collecting and separating unit 5 and a control unit 6 which are independent modules, wherein the modules are connected through pipelines and cables and are dispersed in a cabin 7, and enough space is reserved among different modules, so that subsequent maintenance is facilitated.
The system adopts No. 60 cooling liquid and No. 45 transformer oil as heat exchange media, and takes low-temperature water at 7-12 ℃ as a cold source. The seawater pumping device is applied to ships, and can pump seawater at a certain depth to serve as a cold source, so that a refrigerating unit can be avoided, and equipment cost and energy can be saved.
The cooling water unit 2 is composed of a cooling water inlet pipe 21 and a cooling water return pipe 22. Conventional accessories such as flow, temperature and pressure sensors are arranged on the cooling water inlet pipe 21; the ends of the cooling water inlet pipe 21 and the cooling water return pipe 22 are provided with electromagnetic valve branches 23 for balancing the pressure of inlet water and return water.
The water-cooling heat exchange unit 3 consists of three water-cooling plate heat exchangers arranged in parallel 31 and operates in a dual-purpose one-standby mode. The oil-cooled heat exchange unit 4 is composed of three oil-cooled plate heat exchangers 41 arranged in parallel. The cooling water channels of the water-cooling plate heat exchanger 31 and the oil-cooling plate heat exchanger 41 respectively form a circulation loop with the cooling water inlet pipe 21 and the cooling water return pipe 22 through pipelines, and the cooling water carries away heat and is discharged after exchanging heat in each plate heat exchanger.
The heat exchange circulation of the No. 60 cooling liquid in the water-cooling heat exchange unit 31 is as follows: the coolant in the liquid storage tank 1 is sent into the heat exchange medium channel of the water-cooled plate heat exchanger 31 through the filter 11 and the liquid supply pump 12, is cooled by heat exchange with the cooling water and is sent into the liquid distributor 51 of the liquid collecting and distributing unit 5, is sent to the heat exchange of a plurality of electronic equipment loads through the liquid distributor 51, and is sent into the liquid storage tank 1 to complete the circulation after passing through the liquid collector 52 for high-temperature coolant after the heat exchange of a plurality of electronic equipment loads.
The heat exchange circulation of the 45# transformer oil in the oil-cooled heat exchanger 41 is as follows: 45# transformer oil in the equipment is sent into a heat exchange medium channel of the oil-cooled plate heat exchanger through an oil filter 42, an oil supply pump 43 and an oil drying filter 44, and returns to the equipment after exchanging heat with cooling water and reducing the temperature, so that circulation is completed. In order to avoid the influence of expansion and contraction of 45# transformer oil in the circulation process and generated gas on the heat exchange circulation, an expansion oil tank 45 is connected to the circulation pipeline.
The control unit 6 adopts a conventional air-conditioning control principle, collects data such as pressure, flow and temperature through sensors mounted on each pipeline, and controls actuating elements such as a liquid supply pump and a proportional control valve to regulate the system. Because the heat exchange amount of different load demands is different, install electronic proportion control valve and flowmeter respectively on the branch road pipeline that cooling water inlet tube and cooling water wet return and each plate heat exchanger are connected to through the mode of adjusting cooling water flow, adjust the cooling capacity.
