Problems solved by technology

[0002] Radio and television transmission equipment, whether it is a traditional analog transmitter or a rapidly developing digital transmitter, its power amplifier final stage amplification unit has the characteristics of high power, high energy consumption, and low efficiency, and generates high heat during operation, and Excessive temperature of expensive MOS power amplifier pins not only reduces efficiency, but also often causes damage
At this stage, mainstream digital transmitters at home and abroad mostly use natural air cooling, circulating water cooling and heat pipe cooling systems, and the transmitter room mostly uses air-conditioning cooling and fan pumping heat to dissipate heat. These cooling methods are noisy, dusty, and inefficient. Low, long-term operation leads to a high failure rate of the transmitter equipment, and the most important thing is that the power consumption is large, which leads to high operation and maintenance costs of the transmitting station

Embodiment Construction

[0022] like figure 1 As shown, a new high-power radio and television high-power digital transmitter submerged high-efficiency oil-cooled heat dissipation device includes a power amplification unit, and also includes an oil-cooled cabinet 1, a heat exchanger 15, a water tower radiator 17, and an air-cooled radiator 14. Cooling oil is filled in the cooling cabinet 1, and the power amplifying unit 4 is arranged in the oil cooling cabinet 1 and immersed in the cooling oil, and the cooling oil is dimethyl silicone oil.

[0023] The oil-cooled cabinet 1 adopts a double-layer nested structure made of SUS304 with a thickness of 2.5mm. There is a keel armor between the two layers of SUS304, and the interior is filled with non-combustible heat-insulating materials. The front of the oil cooling cabinet 1 is provided with an oil inlet 20 and an oil outlet 21, and the side is provided with a control box port, a signal line port and a power line port. Oil outlet 21 is connected with heat e...

Abstract

The invention discloses a novel immersed efficient oil-cooling heat dissipation device for a radio and television high-power digital transmitter. The system comprises a power amplification unit, an oil cooling cabinet, a heat exchanger, a water tower radiator and an air cooling radiator, cooling oil is contained in the oil cooling cabinet, the power amplification unit is arranged in the oil cooling cabinet and immersed in the cooling oil, and the oil cooling cabinet is provided with an oil inlet and an oil outlet; wherein the oil outlet is respectively connected with a heat exchanger and an air-cooled radiator, the heat exchanger is connected with a water tower radiator, the air-cooled radiator and the heat exchanger are respectively connected with the oil inlet, the heat exchanger is connected with the water tower radiator, and the air-cooled radiator, the heat exchanger and the oil-cooled cabinet form a parallel loop. The power amplification unit directly transmits heat to the cooling oil, the cooling oil absorbs the heat and performs heat exchange through the heat exchanger or the air-cooled radiator, and the cooling oil flowing into the oil-cooled cabinet is kept in a lower range, so that the working temperature of the power amplification unit in the oil-cooled cabinet is constant, and the effect of overall efficient heat dissipation is achieved.
