Problems solved by technology
[0003] This technology has a simple structure and low cost; but when the temperature of the cooling air a is low, the speed of the centrifugal fan motor cannot be reduced to reduce the air volume of the cooling air a, and thus the power consumption of the cooler system cannot be reduced
Therefore, the air volume of the cooling air a remains unchanged, so that the temperature of the cooling air c0 is also relatively low, and the temperature is not constant; it is not conducive to heating

Embodiment Construction
[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0026] combined with image 3 , with Figure 4 , with Figure 5 , with Image 6 .
[0027] When the present invention is specifically implemented, a centrifugal fan cooling system includes a primary cooler 1, a secondary cooler 2, a tertiary cooler 3, an oil and gas barrel, a centrifugal fan, a frequency converter, a controller, a compressor, a TA and TQ two temperature sensors, a primary cooler 1 is placed at the air outlet on the top of the centrifugal fan, and the hot fluid a2 flowing out from the oil and gas barrel passes through the primary cooler 1 to exchange heat with the cooling air bh2 discharged from the centrifugal fan Afterwards, thermal fluid b2 and cooling air c2 are generated, and then cooling air c2 flows out of the cooling system, and the thermal fluid b2 flows into the secondary cooler 2 for heat exchange with cooling air a, generating ...

The invention relates to a cooling system of a centrifugal fan. The cooling system comprises a primary cooler 1, a secondary cooler 2, a ternary cooler 3, an oil-gas bucket, the centrifugal fan, a frequency converter, a controller, a compressor, a TA temperature sensor and a TQ temperature sensor. The primary cooler 1 is put at the position of an exhaust port in the top of the centrifugal fan, after hot fluid a2 flowing out of the oil-gas bucket and cooling air bh2 exhausted from the centrifugal fan suffer from heat exchange through the primary cooler 1, hot fluid b2 and cooling air c2 are generated, then the cooling air c2 flows of the cooling system, after the hot fluid b2 flows into the secondary cooler 2 to suffer from heat exchange with cooling air a, hot fluid c2 and cooling air b2 are generated, then the hot fluid c2 flows out of the cooling system to enter the compressor, and hot compressed air 2 flowing out of the oil-gas bucket flows into the ternary cooler 3. Compared with the prior art, the cooling system has the beneficial effects that the power consumption of the cooling system is reduced, and the temperature of the cooling air c2 is increased.
Description
technical field [0001] The invention relates to the technical field of a centrifugal fan cooling system, in particular to a centrifugal fan cooling system. Background technique [0002] Such as figure 1 The compressor inhales air to compress, and generates a large amount of heat during the compression process, and the hot fluid C0 enters the compressor for cooling and lubrication; then discharges the hot mixture O to the oil and gas barrel, and then the oil and gas barrel separates the hot mixture O into heat Fluid a0 and hot compressed air 0. The hot fluid a0 flows to the temperature control valve and cooler 2. When the temperature of the thermal fluid a0 is lower than the set temperature of the temperature control valve, the thermal fluid a0 enters the compressor; when the temperature of the thermal fluid a0 is greater than the set temperature of the temperature control valve, the thermal fluid a0 enters the cooler 2 to exchange heat with the cooling air a, Generate the...
