[0023] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0024] like Figures 1 to 5As shown, a portable oil cooler includes: a casing 1, a connecting base 2, tracks 3, oil cooling pipes 4, a drive base 5, and an exhaust fan 6. The casing 1 has an opening at its bottom and on one vertical surface. Inside the casing 1, oil cooling pipes 4 extend in a ring shape from top to bottom in one direction. A storage box 14 is located within the opening at the bottom of the casing 1. The connecting base 2 is located on the side of the storage box 14 away from the casing 1. Baffles 35 are located on the opposite sides of the connecting base 2. Two parallel tracks 3 are arranged below the connecting base 2 and between the two baffles 35. Each track 3 is connected end-to-end. The track 3 is arranged in a circular loop, with several guide wheels 31 arranged sequentially in one direction. Each of the two guide wheels 31 has a hole, and a drive shaft 51 runs through the hole. The ends of the two drive shafts 51 away from the two guide wheels 31 are connected to a corresponding drive base 5. Each guide wheel 31 has an annular groove on the side facing the drive base 5. A limiting ring 36 is embedded in the annular groove of the guide wheel 31. A fixing rod 361 is fixedly connected to the limiting ring 36 and the connecting base 2.

[0025] This utility model uses a track 3 to move the casing 1 of the oil cooler. When the track 3 moves on the ground, it has a large contact area with the ground, which can better engage the ground and make the movement more stable. In addition, it can avoid shaking of the casing 1 and oil cooling pipes 4 above. Therefore, it can further reduce secondary damage to this utility model during the movement. The track 3 of this utility model moves by driving the base 5, which can reduce the need for manual pushing.

[0026] With the above structure, it should be further explained that the track 3 used in this utility model is composed of several hard rubber sheets arranged in sequence and wrapped in a chain. Therefore, the teeth on the outer surface of the guide wheel 31 can engage with the gaps between the hard rubber sheets. When the guide wheel 31 is rolling, the teeth on the outer surface engage with the gaps between the hard rubber sheets, thereby driving it to move back and forth in one direction.

[0027] A hinged door 11 is provided at the vertical opening of the chassis 1. Several hinges are connected between a vertical edge of the hinged door 11 and the edge of the opening on the vertical surface of the chassis 1, and are arranged sequentially from top to bottom along both sides. The hinged door 11 opens and closes in a fan shape outward from the vertical opening of the chassis 1 through the several vertically arranged hinges. The hinged door 11 has a window, and a glass plate 12 is inlaid in the window. Two vertically arranged clamping plates 13 are provided at the edge of the hinged door 11 away from the hinges. A closing plate 10 is clamped between the two clamping plates 13. A protrusion is provided on the side of the two clamping plates 13 that is in close contact with the closing plate 10. The two clamping plates 13 are respectively embedded in the closing plate 10 by the protrusions. The closing plate 10 swings in a fan shape in one direction through the two clamping plates 13. Several magnets are inlaid on the side of the closing plate 10 facing outward from the chassis 1.

[0028] With the above structure, it should be further explained that the opening and closing door 11 is set so that when the oil cooling pipe 4 is damaged or deformed, the inside of the chassis 1 can be repaired by opening the opening and closing door 11.

[0029] Furthermore, in the closed state of the opening and closing door 11, in order to further inspect the oil cooling pipe 4 and know at any time whether any abnormality has occurred, the opening and closing door 11 is also provided with a hollow window, and the window is inlaid with a transparent glass plate 12. The glass plate 12 not only provides a visual observation, but also prevents the internal heat from escaping to the outside.

[0030] When the opening and closing door 11 covers the vertical opening of the chassis 1, the closing plate 10 on the edge is attached to the outside of the chassis 1, and several magnets of the closing plate 10 are attracted to the outer surface of the chassis 1, thereby achieving the effect of closing and locking. The use of magnetic attraction to fix it makes it easy to open and close the opening and closing door 11.

[0031] The closing plate 10 has an embedding groove on the side away from the chassis 1. A control panel 101 is installed in the closing plate 10 through the embedding groove. A wiring plug is provided in the embedding groove of the closing plate 10 and is electrically connected to the control panel 101. The wiring plug of the closing plate 10 extends into the chassis 1 through a conduit and is connected to the connecting base 2.

[0032] With the above structure, it should be further explained that the control panel 101 used in this utility model is the only tablet computer that can be controlled by touch screen. The control panel 101 can be touched and start the relevant commands, and wirelessly transmit the commands to the control unit 20. Then, the control unit 20 can control the electrical components of this utility model to start and stop.

[0033] When the control panel 101 is normally inserted into the recessed slot of the closed plate 10, it is electrically connected to the wiring plug inside the recessed slot. At this time, the control panel 101 is in a power-connected state (charging state), and the control panel 101 can also be operated in this state. When it is necessary to move the present invention, the control panel 101 can be pulled out and operated as a wireless remote control device to transmit the movement command to the present invention.

[0034] The power supply for the closing plate 10 is provided by the control unit 20, which passes the electrical conduit through the chassis 1 and extends it outside the chassis 1 until it is connected to the wiring plug of the closing plate 10.

[0035] A round hole is provided on the top of the chassis 1. An exhaust fan 6 is fixed at the edge and above the round hole of the chassis 1. A mesh layer is provided at the edge of the opening above the exhaust fan 6. The side of the exhaust fan 6 away from the mesh layer faces the inside of the chassis 1.

[0036] With the above structure, it should be further explained that the mesh layer above the exhaust fan 6 can prevent external dust from falling into the chassis 1, and the exhaust fan 6 can further exhaust the heat carried out by the oil cooling pipe 4 to the outside, avoiding heat accumulation and thus reducing the heat dissipation effect.

[0037] The storage box 14 is connected to the base 2 by a conduit; the oil cooling pipe 4 is fixed inside the box 1 by several support brackets.

[0038] With the above structure, it should be further explained that the oil cooling pipe 4 is arranged in a ring and extends in one direction. This structure can increase the heat absorbed by the oil cooling pipe 4 after it is bent from top to bottom, so that the surface of the oil cooling pipe 4 can have full contact with the outside, thereby further increasing the heat dissipation, and also allowing the exhaust fan 6 to exhaust the heat outward.

[0039] The storage box 14 is equipped with a liquid pumping motor 42, which is connected to one end of the oil cooling pipe 4. The other vertical surface of the box 1 is equipped with a fixing plate 15, which has at least two openings. One side of one of the two openings is connected to an external infusion pipe and is connected to the other end of the oil cooling pipe 4. The other opening is connected to the liquid pumping motor 42 by a conduit.

[0040] With the above structure, it should be further explained that the liquid pumping motor 42 of this utility model is a liquid pumping pump. It draws the cooling oil inside the external oil cooling pipe 4 until it is drawn out to the oil cooling pipe 4 which is only placed in a bent position. It dissipates heat and removes heat from the cooling oil. After the oil cooling pipe 4 is placed in a bent position, it returns to the outside and circulates to remove heat.

[0041] A baffle 35 is fixed on the front and rear sides of the connecting base 2. The inner side of the connecting base 2 is hollow, and an insertion port is opened on one side of the connecting base 2. The opening of the insertion port of the connecting base 2 is covered by a cover plate. At least four guide rails 21 are provided inside the connecting base 2. One end of the four guide rails 21 in the connecting base 2 extends to the edge of the opening of the insertion port, and the other end extends in the opposite direction. A control unit 20 is slidably inserted into the connecting base 2 through the four guide rails 21. An electrical conduit is connected to the outside of the control unit 2 and extends to the outside of the connecting base 2, and is electrically connected to the external power supply.

[0042] With the above structure, it should be further explained that the baffle 35 can block external obstacles and prevent them from getting stuck in the track 3, which would cause the track 3 to jam and be damaged.

[0043] The control unit 20 is slid inward through the opening of the insertion port of the connecting base 2. In order to limit and fix the control unit 20, a sliding groove matching the four guide rails 21 is provided below the control unit 20. Therefore, after the control unit 20 is inserted into the connecting base 2, the four guide rails 21 can limit the left and right space of the control unit 20, thereby preventing left and right swaying. The cover plate of the insertion port can support the control unit 20 to prevent back and forth swaying. At the same time, a heat dissipation sponge is provided inside the insertion port of the connecting base 2. In addition to providing heat dissipation, the heat dissipation sponge can also prevent the control unit 20 from being stuffed up and down, thus preventing collisions when it sways.

[0044] An electrical contact piece is provided on the downward-facing side of the control unit 2 inside the connector base 2, and a contact spring is provided on the side of the connector base 2 facing the electrical contact piece. The electrical contact piece and the contact spring are electrically connected to each other. Several electrical conduits are inserted inside the connector base 2. One end of the several electrical conduits is connected to the contact piece, and the other end of the several electrical conduits extends to the outside of the connector base 2. The control unit 20 is also equipped with a wireless receiving structure and a reserve power supply.

[0045] After adopting the above structure, it should be further explained that the control unit 20 used in this utility model is composed of several circuit boards.

[0046] When the control unit 20 is inserted into the insertion port, the electrical contact piece and the contact spring are pressed and made into contact, thereby achieving a close connection between the two. Since both the electrical contact piece and the contact spring are made of metal, they can transmit electrical energy and signals between them. This invention avoids the use of a plug, which is prone to wear and poor contact due to prolonged plugging and unplugging. Furthermore, the contact spring used in this invention is normally an outward-curving arc, which avoids direct contact between the plug and minimizes contact gaps.

[0047] After the electrical contact piece and the contact spring make contact, the control unit 20 makes an electrical connection to the electrical component of this utility model until the control panel 101 controls its start and stop.

[0048] Each guide wheel 31 has a filling groove on the side away from the limiting ring 36; a clamping plate 32 is provided on the outer side of the filling groove of each guide wheel 31, the clamping plate 32 has a protrusion, and the clamping plate 32 is embedded in the filling groove of the guide wheel 31 by the protrusion; the number of clamping plates 32 is the same as the number of guide wheels 31, and the clamping plates 32 are connected by a crossbar; a limiting rod 34 is provided on the side of each clamping plate 32 away from the guide wheel 31, and one end of the limiting rod 34 is connected by a crossbar between two clamping plates 32, and the other end of the limiting rod 34 is connected to the outside of the connecting base 2; each guide wheel 31 has a tooth on its outer surface, and the tooth engages with the inner side of the track 3; each guide wheel 31 and each limiting ring 36 are respectively held by a guide wheel 31, and are respectively suspended below the connecting base 2 by the limiting rod 34 and the fixing rod 361.

[0049] With the above structure, it should be further explained that the guide wheel 31 is clamped and fixed by the limiting ring 36 and the clamping plate 32 to avoid derailment from left and right during rolling. The limiting rod 34 and the fixing rod 361 are fixed to the outside of the connecting base 2. At the same time, the limiting rod 34 and the fixing rod 361 support the connecting base 2 to prevent the connecting base 2 from squeezing and contacting the track 3 and the guide wheel 31.

[0050] At least four drive bases 5 are provided, arranged in pairs, and located at the front and rear ends between two tracks 3. The two drive bases 5 located at the front or rear each use a drive shaft 51 inserted into the corresponding guide wheel 31. A central wire plate 50 is provided between the two pairs of drive bases 5, and a wire tube extends from each of the two pairs of drive bases 5. The two pairs of drive bases 5 use wire tubes to connect to the central wire plate 50. The central wire plate 50 is electrically connected to the wire tube and is connected to the electrical wire tube extending from the connecting base 2.

[0051] With the above structure, it should be further explained that the two drive bases 5 at the front end are forward rotating motors, which drive the corresponding two guide wheels 31 to move forward and simultaneously output rolling in one direction. At this time, the two drive bases 5 at the rear do not start. When it is necessary to turn, one of the two drive bases 5 stops rolling, while the other drive base 5 continues to operate, rotating axially in one direction with the non-rolling drive base 5 as the center, thereby achieving a special direction.

[0052] The two drive bases 5 located at the rear end operate in the same manner as the two drive bases 5 located at the front end, and will not be described in detail here. The two drive bases 5 located at the rear end are used to drive the present invention to move backward.

[0053] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
