[0031] The present application will be further described in conjunction with the embodiments.

[0032] Embodiment:

[0033] Referring to the drawings shown in the accompanying drawings, Figure 1 - the accompanying drawings, Figure 8 The double-core parallel type automobile oil cooler shown in the accompanying drawings is used for cooling the engine oil and lubricating oil in the automobile to ensure the performance of the engine oil and lubricating oil circulating in the automobile, comprising a box body 100, a cavity 101 is formed in the box body 100, the cavity 101 is filled with cooling liquid, and the box body 100 is also connected with a liquid inlet pipe and a liquid outlet pipe (not shown in the figure) respectively, which are used for replacing the cooling liquid in the cavity 101, the replacement of the cooling liquid can ensure that the cooling liquid in the cavity 101 is always at a lower temperature, thereby better heat exchange with the engine oil or lubricating oil, thereby realizing efficient cooling and temperature reduction, and the cavity 101 is also provided with an air outlet pipe, a one-way valve is installed on the air outlet pipe, and a filter membrane is also provided in the air outlet pipe, which allows gas to pass through but not liquid, and the inside of the cavity 101 is connected with rubber rings 110 on both sides, and the outer wall of the box body 100 is also connected with pipe fittings 120, which are provided with two, used as an oil inlet pipe and an oil outlet pipe respectively, and connected into the automobile oil circuit to ensure the normal use of the oil circuit.

[0034] Particularly, in order to ensure the effective cooling of the oil, two pipe cores 200 are arranged in the box body 100, the pipe cores 200 are also part of the oil circuit, in this case, the pipe cores 200 also have the function of temporarily storing oil, and the oil in the pipe cores 200 can have sufficient time to exchange heat with the cooling liquid in the cavity 101 to ensure sufficient cooling of the oil. The pipe cores 200 are arranged in two groups and located inside the cavity 101, the outer wall of the pipe cores 200 is uniformly connected with a plurality of ribs 210, the inside of the pipe cores 200 is respectively provided with an oil accumulation groove 201 at both ends, and the end of the pipe cores 200 is also connected with a connecting pipe 220 which is in communication with the oil accumulation groove 201, the two oil accumulation grooves 201 are communicated by a plurality of spiral grooves 202 in the middle, it is worth noting that the end of the pipe core 200 is fixedly installed with the connecting pipe 220, the connecting pipe 220 can be in communication with the two pipe fittings 120 arranged on the outer wall of the box body 100, so that the oil in the oil circuit can enter the inside of the arranged pipe core 200, it is worth noting that the pump body is installed on the pipe fitting 120 used as the oil inlet pipe to ensure that the oil in the oil circuit can flow in the predetermined direction, when the oil in the oil circuit enters the pipe core 200, it will be temporarily stored in the oil accumulation groove 201 and enter the spiral groove 202, it is worth noting that in combination with the rotating connection between the outer wall of the connecting pipe 220 and the outer wall of the moving ring 330, when the oil in the flow state flows in the spiral groove 202, the pipe core 200 will rotate in the cavity 101, in combination with the plurality of ribs 210 fixedly connected to the outer wall of the pipe core 200, they will also move together, thereby increasing the flow of the cooling liquid in the cavity 101, thereby enabling the cooling liquid to fully exchange heat with the oil flowing in the pipe core 200, and it is worth noting that when the oil flows in the spiral groove 202, the oil can constantly change position to avoid the phenomenon that the oil in the static state cannot fully exchange heat with the cooling liquid, while the other pipe core 200 which does not communicate with the oil circuit is in a static state and is located at one side of the cavity 101, through the rotation of the other pipe core 200, it will make the cooling liquid in the cavity 101 fully flow, which can also ensure that the oil temporarily stored in the pipe core 200 fully exchanges heat with the cooling liquid, then when it is reconnected with the oil circuit, in combination with the pump body installed on the oil inlet pipe, it will re-inject the oil to be cooled in the pipe core 200, the oil in it which has been fully cooled will be re-injected into the oil circuit.

[0035] In the case, if the position of the pipe core 200 is fixed, only a single oil passage can be cooled, and the cooling efficiency is limited, therefore, in the case, the pipe core 200 is provided with two groups, and a driving mechanism is also provided, which is used to adjust the position of the pipe core 200 inside the cavity 101, through the adjustment, only one pipe core 200 needs to be ensured to be in communication with the oil passage of the automobile, and the normal use of the oil or lubricating oil can be ensured, and it is worth noting that when the driving mechanism adjusts the position of the pipe core 200, the oil in the oil passage is at rest by default, that is, the pump body at the oil inlet pipe is in a non-running state, specifically, the driving mechanism includes a moving plate 420 located outside the box body 100, the moving plate 420 is fixedly connected with the output end of the external cylinder, and the two ends of the moving plate 420 are connected with two clamping plates 400 through connecting rods 410 respectively, and the inside of the clamping plate 400 is provided with a circular hole 401.

[0036] In particular, in order to ensure that the driving mechanism can keep the pipe core 200 in communication with the oil passage after adjusting the pipe core 200, and in the case, the pipe core 200 and the pipe 120 arranged on the box body 100 are in stable communication, a connecting ring 300 is also arranged, which is elastically connected to the two ends of the pipe core 200 and is in sliding fit with the inside of the circular hole 401, the inner end of the connecting ring 300 is connected with a ring-shaped capsule 320, the ring-shaped capsule 320 is filled with inert gas, the inner end of the ring-shaped capsule 320 is connected with a moving ring 330, and the ring-shaped capsule 320 is in communication with the capsule 140 adhered to the inner wall of the cavity 101 through the hose 310, and the ring-shaped capsule 320 is also in communication with the external air pump through the one-way pipe 311, and the circular pipe 340 fixedly connected to the outer end of the connecting ring 300 is also included, specifically, the outer wall of the end portion of the pipe core 200 is also fixedly installed with a circular ring 230, and the circular ring 230 and the outer wall of the connecting pipe 220 form a lap joint groove 203; the outer wall of the moving ring 330 and the inner wall of the lap joint groove 203 are in sliding fit, the moving ring 330 always slides in the lap joint groove 203, and the connecting pipe 220 and the pipe 120 are in communication through the middle part of the moving ring 330, the middle part of the ring-shaped capsule 320 and the circular pipe 340 fixedly connected to the connecting ring 300;

[0037] And it is worth mentioning that when the tube core 200 is not in communication with the pipe 120, the end of the outer wall of the circular tube 340 is in contact with the inner wall of the cavity 101, sealing the inside of the tube core 200, the outer wall of the circular tube 340 is in sliding fit with the inner wall of the cavity 101, and the circular tube 340 can be sealed by the inner wall of the cavity 101; and when the circular tube 340 is sealed, the annular capsule 320 is compressed, and the inert gas in its interior enters the capsule 140 from the hose 310 and enters the cavity 101 through the plurality of through holes provided on the capsule 140, in this way, the flowability of the coolant in the cavity 101 can be effectively increased, thereby effectively exchanging heat with the oil in the tube core 200, realizing sufficient cooling of the oil in the tube core 200; when the external cylinder drives the tube core 200 to adjust the position, the circular tube 340 will be in communication with the pipe 120, at this time the annular capsule 320 restores, and the inert gas is injected into its interior through the provided one-way pipe 311, and in this state, the elastic force of the annular capsule 320 can ensure the stable contact between the circular tube 340 and the pipe 120, ensuring its communicatability.

[0038] And it is worth mentioning that when the external cylinder adjusts the position of the tube core 200 in the cavity 101, part of the circular tube 340 is in communication with the pipe 120, and part of it is exposed in the cavity 101, which may cause oil leakage, therefore, in this case, a rubber ring 110 is also provided at this position, which forms a relatively sealed space with the inner wall of the cavity 101, used for temporarily storing the leaked oil from the pipe 120, and the leaked oil during the adjustment of the position of the tube core 200 can be temporarily stored, and because the rubber ring 110 is still in the cavity 101, and the cavity 101 is filled with coolant, the leaked oil in the rubber ring 110 can still be well cooled, and it is worth mentioning that when the driving mechanism adjusts the position of the tube core 200, the oil in the oil circuit remains stationary, and the amount of leaked oil is not much, therefore most of the oil can still be well cooled in the tube core 200, the bottom surface of the rubber ring 110 is provided with an oil outlet groove 111, and the oil outlet groove 111 is also connected with an oil conveying pipe 130; and the oil conveying pipe 130 is in communication with one of the two pipes 120, here the pipe 120 refers to the oil outlet pipe.

[0039] In the case, in order to ensure the flowability of the coolant in the cavity 101 during the whole oil cooling process, the lap plate 500 is arranged outside the pipe core 200 and is in sliding fit with the inner wall of the cavity 101, and the compression capsule 510 is fixedly installed on the inner wall of the cavity 101; when the external cylinder drives the arranged pipe core 200 to move in the cavity 101, the outer wall of the arranged lap plate 500 contacts and extrudes the outer wall of the compression capsule 510, and the gas in the compression capsule 510 enters the cavity 101 through the plurality of gas outlets on the outer wall, when the driving mechanism drives the arranged pipe core 200 to adjust the position, the lap plate 500 arranged on one side of the pipe core 200 also moves together and extrudes the compression capsule 510 installed in the cavity 101, so that the inert gas in the compression capsule 510 enters the coolant, increases the flow of the coolant in the cavity 101, and makes the coolant fully exchange heat with the oil.

[0040] In the case, in order to ensure the intelligence of the driving mechanism, the triggering unit is further included, which includes a metal sheet fixedly installed on the ring 230 and a metal protrusion fixedly installed on the connecting ring 300; when the annular capsule 320 is extruded, the metal sheet and the metal protrusion are lapped, and when the contact time of the two is 3s, the external cylinder is reversely moved, and of course the contact time is not limited to a specific time, which is related to the length of the pipe core 200 and the time required for the pump body to replace the oil in the pipe core 200, and specifically, the contact time is enough to make the pump body replace all the oil in the pipe core 200, and then the external cylinder in the driving mechanism is reversely moved, so that different pipe cores 200 are connected to the oil circuit, and thus the oil is efficiently cooled.

[0041] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalent ones; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present application.
