outlets on the oil cooler and the air cooler are respectively communicated with the first water inlet channel 22;

the water pump 25 is disposed on a pipeline through which the water tank 23 and the three-way manifold 15 are communicated.

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 oil 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 oil cooler and the oil cooler from a first water outlet end 27 and a second water outlet end 28 of the cooling water, the air to be cooled and the lubricating oil to be cooled of the medium channels in the oil cooler and the oil cooler are cooled, and then the cooling water returns to the water tank 23 from outlets of the oil 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 reciprocating motion carries out the purpose of scrubbing in the gas cooler, and the incrustation scale that brushes away passes through second outlet channel 7, third outlet channel 6 are followed discharge in the cooling water cavity 4 prevents 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.

The working principle of the anti-blocking mechanism is as follows: when a certain water outlet channel in the cooling water cavity 4 is blocked due to accumulation of scale or impurities, the water pressure of a cavity in the cooling water cavity 4 of the water outlet channel is increased until the bypass valve 16 is triggered to work, high-pressure water is led into the cavity of the mounting seat 20 from the bypass valve 16 to further push the piston 18 to move, the piston 18 further pushes the ejector rod 29 to lift the cooling water cavity 4 from the blocked water outlet channel, the accumulated scale or impurities are ejected to dredge the blocked water outlet channel, after the blocked water outlet channel is dredged, the bypass valve 16 stops working, at the moment, water in the cavity in the mounting seat 20 can be drained out through the pressure relief valve 17, the ejector rod 29 resets under the action of the first elastic piece 19, and when the ejector rod 29 cannot dredge the blocked water outlet channel, the water in the cooling water cavity 4 can also be drained out in an emergency manner through the pressure relief valve 17, the safety 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.

Further, a scraper 1104 is disposed at the boundary between the substrate 1101 and the outer sidewall of the media channel.

By providing the scraper 1104, when the substrate 1101 moves, the scraper 1104 can scrape off the scale attached to the medium passage, and the cleaning effect of the cleaning mechanism is increased.

The water tank 23 is divided into two chambers by the filter plate 26, and water introduced into the water tank 23 from the first water inlet passage 22 is cooled by the filter plate 26 and then discharged from the first water outlet passage 24, so that cooling water can be recycled, and the use cost of the device is reduced.

Further, the scraper 1104 is a ring-shaped structure with a triangular cross section, and the scraper 1104 includes a lateral side, a vertical side, and a vertical side, wherein the vertical side is connected to the substrate 1101, and the lateral side is slidably engaged with the outer sidewall of the media path.

In the invention, the scrapers 1104 can be symmetrically arranged on two sides of the substrate 1101, and the scrapers 1104 are in sliding fit with the outer side walls of the medium channel, so that the scrapers 1104 can be prevented from damaging the side walls where the medium can reach, and when the scrapers 1104 pass through the scale, the triangular blade tips can scrape off the scale.

Further, the filter plate 26 is made of activated carbon.
