DETAILED DESCRIPTION

[0018] The present invention will be further described with reference to the accompanying drawings.

[0019] refer to Figure 1- 4. A 120kW offshore platform low-noise explosion-proof air-to-air cooler. The cooler comprises an air inlet box 1, a cooler housing 2 and an air outlet box 3 which are connected in sequence. The cooler housing 2 is mounted on the generator housing through bolts. A fan assembly 5 is provided at the air inlet 12 of the air inlet box 1. Six primary filters 4 are provided at the air outlet 13 of the air outlet box 3 to filter the air. Cold air is drawn from the outside into the cooler housing 2 through the fan assembly 5. The cooler housing The bottom of 2 is provided with a left cold air inlet 6, a hot air outlet 7 and a right cold air inlet 8 in sequence, and the left cold air inlet 6, the hot air outlet 7 and the right cold air inlet 8 are all connected with the generator chamber. A plurality of heat dissipation pipes are provided in the cooler box 2, and the heat dissipation pipes are arranged above the hot air outlet 7 and perpendicular to the air outlet direction of the hot air outlet 7. The inner walls of the air inlet box 1, the cooler box 2 and the air outlet box 3 are provided with a sound insulation layer, and the sound insulation layer is filled with sound-absorbing cotton 9.

[0020] The utility model draws air from the outside through the fan assembly 5, passes through the air inlet box 1 and then enters the cooler box 2. The hot air in the generator chamber enters the cooler box 2 from the hot air outlet 7 under the action of negative pressure, and exchanges heat with the cold air and the heat dissipation pipe. A part of the hot air is discharged through the air outlet box 3, and the primary filter 4 on the air outlet box 3 plays a filtering role. The cooled air returns to the generator chamber through the left and right cold air inlets to cool the generator. The cooling effect is good, and a sound insulation layer is set on the inner walls of the air inlet box 1, the cooler box 2 and the air outlet box 3 using sound insulation cotton 9 to absorb the noise generated when the cooler is working, thereby achieving the purpose of reducing noise.

[0021] The fan assembly 5 of the present invention includes two low-noise explosion-proof fans 14 arranged in a fan cover 15. The fan cover 15 is at the air inlet 12 of the air inlet box 1. The two low-noise explosion-proof fans 14 are symmetrically arranged front to back, which improves the efficiency of exhaust and accelerates the entry of cold air, improves the cooling efficiency, and reduces noise. A filter 16 is provided on the outside of the fan cover 15 to filter impurities in the air and prevent debris from entering the cooler and affecting its use. On the other hand, an explosion-proof junction box 10 is provided on the outside of the cooler box 2. The use of the explosion-proof junction box 10 and the explosion-proof fans and the use of seamless steel pipes for the heat dissipation pipes also meet the offshore explosion-proof requirements.

[0022] In the present invention, the six primary filters 4 are respectively connected to corresponding positions of the mounting frame 11 by snap buckles. When one of the filters is damaged, it is easy to replace without having to remove all of them, thereby improving the practicality of the device.

[0023] The air inlet box, the cooler box body and the air outlet box body of the utility model are connected by bolts, and all the bolt fasteners of the cooler are sealed with silicone sealant, which improves the corrosion resistance of the device and meets the needs of offshore work.
