[0043] refer to Figures 1 to 4 At least one embodiment provides a high-pressure resistant radiator specifically for high-pressure screw compressors, comprising: an oil cooling mechanism 1, which includes an oil inlet pipe 11, an oil outlet pipe 12, and an oil cooling component 13. The oil inlet pipe 11 is connected to the oil outlet pipe 12 through the oil cooling component 13, so that the cooling oil can fully contact the oil cooling mechanism 1, serving as a channel for the cooling oil. The faster the cooling oil flows, the higher the pressure and the faster the cooling speed. An air cooling mechanism 2, which is in contact with the oil cooling mechanism 1 on its side, includes an air inlet pipe 21, an air outlet pipe 22, and an air cooling component 23, so that the cooling air can fully contact the air cooling mechanism 2, thereby improving the cooling efficiency. Both the oil cooling mechanism 1 and the air cooling mechanism 2 are vacuum brazed to improve their pressure resistance.

[0044] In some embodiments, the oil inlet pipe 11 and the oil outlet pipe 12 are located on the same side of the oil cooling component 13; the pipe wall of the oil inlet pipe 11 and the pipe wall of the oil outlet pipe 12 are in contact.

[0045] In some embodiments, the wall of the oil inlet pipe 11 is in contact with the wall of the air outlet pipe 22; the oil outlet pipe 12 is separated from the air cooling mechanism 2; the oil cooling component 13 is provided with a plurality of oil channels 14 for transmitting cooling oil through the plurality of oil channels 14, thereby increasing the contact area between the brazed partition 16 and the cooling oil and thus improving the cooling efficiency.

[0046] In some embodiments, an oil manifold 15 is provided on the side of the oil heat sink 13 away from the oil inlet pipe 11 and the oil outlet pipe 12, which serves as an intermediate pipe for the transmission of cooling oil; the oil manifold 15 is connected to the oil channel 14 and is used to receive and supply cooling oil.

[0047] In some embodiments, the oil inlet pipe 11 is connected to a portion of the oil channel 14 to supply oil to the oil manifold 15; the oil outlet pipe 12 is connected to another portion of the oil channel 14 so that the oil inlet pipe 11 is connected to the oil outlet pipe 12 through the oil channel 14 and the oil manifold 15 to form a channel for transporting cooling oil.

[0048] In some embodiments, the air inlet pipe 21 and the air outlet pipe 22 are located at both ends of the air radiator 23; the air outlet pipe 22 is in contact with the oil inlet pipe 11; the air inlet pipe 21 is in contact with the oil manifold pipe 15; and the oil radiator 13 is in contact with the air radiator 23.

[0049] In some embodiments, the heat sink 23 is provided with a plurality of air channels 24; the air inlet pipe 21 is connected to the air outlet pipe 22 through the air channels 24 to form a channel for transporting cooling gas.

[0050] In some embodiments, the cross-sections of the oil channel 14 and the gas channel 24 are both rectangular; both sides of the oil channel 14 and the gas channel 24 include metal partitions 16, which are vacuum brazed to the sides of the oil heat sink and the gas heat sink to increase the pressure resistance of the partitions 16.

[0051] In some embodiments, the oil passage 14 and the gas passage 24 are separated; the partition 16 is made of FAZ20X, an aluminum alloy that contains seven layers of aluminum by mass, which improves the aluminum metal recovery rate.

[0052] Working principle: Before using the high-pressure screw compressor-specific high-pressure resistant radiator, install it in the required position. Connect the oil inlet pipe 11 and oil outlet pipe 12 to the compressor's cooling oil supply device, and connect the intake pipe 21 and exhaust pipe 22 to the compressor's cooling gas supply device. When using the high-pressure screw compressor-specific high-pressure resistant radiator: The compressor's cooling oil supply device supplies cooling oil to the oil inlet pipe 11. The cooling oil passes through part of the oil passage 14 to the oil manifold 15, and then through another part of the oil passage 14 of the oil radiator 13 to the oil outlet pipe 12. The cooling oil in the oil outlet pipe 12 returns to the compressor's cooling oil supply device. Simultaneously, the cooling gas supplied by the compressor's cooling gas supply device passes through the intake pipe 11 to the exhaust passage 24, and then returns to the compressor's cooling gas supply device through the exhaust pipe 22. This achieves cooling of the compressor's cooling gas supply device and cooling oil supply device, enabling continuous cooling of the compressor.
