The working principle of the invention is as follows: when the oil cooler is used, lubricating oil to be cooled and air to be cooled are respectively led into medium channels in the oil cooler and the air cooler, cooling water is led into the three-way manifold 15 from a first water outlet channel 24 of the water tank 23 through a water tank 23 of the circulating water mechanism, the cooling water entering the three-way manifold 15 respectively enters the air cooler and the oil cooler from a first water outlet end 27 and a second water outlet end 28 of the three-way manifold, the air to be cooled and the lubricating oil to be cooled of the medium channels in the air cooler and the oil cooler are cooled, and then the cooling water returns to the water tank 23 from outlets of the air cooler and the oil cooler so as to circulate.
The working principle of the air cooler is as follows: by controlling the two-position three-way electromagnetic valve 2, the cooling water introduced into the gas cooler is reversed, when water is introduced into the second water inlet channel 1, water is not introduced into the third water inlet channel 3, and similarly, when water is introduced into the third water inlet channel 3, water is not introduced into the second water inlet channel 1; when water is introduced into the second water inlet passage 1, because the flow rate of the second water inlet passage 1 is greater than the flow rate of the second water outlet passage 7, the water pressure in the chamber in the cooling water cavity 4 where the second water inlet passage 1 is located is gradually increased, at this time, water is not introduced into the third water inlet passage 3, the third water outlet passage 6 discharges water, the water pressure in the chamber where the third water inlet passage 3 is located is reduced, so that the sliding plate 11 and the sealing plate 12 move towards the chamber where the third water inlet passage 3 is located, and further the cleaning mechanism moves, the outer side wall of the medium passage and the inner side wall of the cooling water cavity 4 are brushed by the brushes on the cleaning mechanism, scale brushes attached to the brushes are removed, and when water is introduced into the third water inlet passage 3, the brushes on the cleaning mechanism move towards the chamber where the second water inlet passage 1 is located, through two-position three way solenoid valve 2 can realize the brush is in the purpose that reciprocating motion scrubbed in the gas cooler, the incrustation scale that brushes away passes through second outlet channel 7, third outlet channel 6 follow discharge in the cooling water cavity 4, prevent pile up the incrustation scale on the medium passageway, reduce the cooling effect.
Meanwhile, when the second water inlet channel 1 leads water into the cooling water cavity 4, water is not led into the cavity where the third water inlet channel 3 is located, and only water is drained, and most of the cooling water with the increased temperature is drained, and after the third water inlet channel 3 leads water into the cooling water cavity 4, compared with the cooling water cavity 4 which is not separated by the sealing plate 12, the temperature of the mixed water in the third water inlet channel 3 is lower, so that the cooling effect is increased, and the same is true in the second water inlet channel 1.
By connecting the sliding plate 11 and the sealing plate 12, the sliding plate 11 may support the sealing plate 12, and when only the sealing plate 12 is provided, the sealing plates 12 may be stuck to the media channels due to uneven moments, which may cause damage to the side walls of the media channels and the side walls of the cooling water chamber 4 in severe cases, and when two sealing plates 12 are arranged in parallel, probably because the friction between the sealing plate 12 and the medium channel is increased, the water pressure required for pushing the sealing plate 12 to move is increased, and the cleaning effect is reduced, the sliding plate 11 can support the sealing plate 12, compared with the friction between the sliding plate 11 and the sealing plate 12 when two sealing plates 12 are arranged in parallel and the medium channel, the friction is smaller, and the operation reliability of the device is improved.

In the present invention, the first elastic member 19 may be a spring.
The working principle of the descaling mechanism is as follows: in the invention, the cooling water cavity 4 and the medium channel are made of stainless steel, because the magnesium rod 13 is more active than stainless steel, when the magnesium rod 13, the medium channel and the cooling water cavity 4 are in the same electrolyte, electrons on the magnesium rod 13 are transferred to the cooling water cavity 4 and the medium channel, so that the cooling water cavity 4 and the medium channel are at a more negative and same potential to replace the cooling water cavity 4 and the medium channel to be consumed by corrosion.
The descaling mechanism, the anti-blocking mechanism and the cooling principle of a medium to be cooled in a medium channel of the oil cooler are the same as those of the oil cooler, after lubricating oil is introduced into the medium channel of the oil cooler, the lubricating oil is discharged from the medium channel after passing through a bent channel formed by a baffle 21 in the medium channel, and as the baffle 21 is made of a magnetic material, when the lubricating oil flows through the baffle 21, scrap iron in the lubricating oil is adsorbed on the baffle 21, so that the lubricating oil is filtered, and the scrap iron in the lubricating oil is prevented from damaging an internal mechanism of the compressor.
