Background

In vehicles such as automobiles, a radiator is an important component of a cooling system. The radiator is generally composed of three parts, namely a liquid inlet chamber, a radiating core body and a liquid outlet chamber. After components such as engine are cooled by the cooling liquid, the cooling liquid can enter the radiator from the liquid inlet chamber, and then heat exchange is carried out between the cooling liquid and cold sources such as outside air through the radiating core body, so that heat is radiated out. The cooled cooling liquid flows out of the radiator from the liquid outlet chamber for subsequent recycling.

Detailed Description

In order to make the technical problem solved by the present invention, the technical solution adopted by the present invention and the technical effect achieved by the present invention clearer, the technical solution of the present invention will be further explained by combining the drawings and by means of the specific implementation manner.

In the description of the present invention, unless expressly stated or limited otherwise, the terms "connected," "connected," and "fixed" are to be construed broadly, e.g., as meaning permanently connected, detachably connected, or integral to one another; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In the present disclosure, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact between the first and second features, or may comprise contact between the first and second features not directly. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

In the description of the present embodiment, the terms "upper", "lower", "left", "right", and the like are used in the orientation or positional relationship shown in the drawings only for convenience of description and simplicity of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.

The present embodiment provides a heat sink, as shown in fig. 1-3, the heat sink includes an inlet chamber 1, a heat dissipation core 2 and an outlet chamber 3, which are sequentially connected. Wherein, be provided with inlet 11 on the feed liquor room 1, heat dissipation core 2 is provided with liquid outlet 31 including setting up many cooling tubes 21 between feed liquor room 1 and play liquid room 3 on the play liquid room 3. The radiator also comprises a piston part 7, the piston part 7 is movably arranged in the liquid inlet chamber 1 and divides the inner cavity of the liquid inlet chamber 1 into a liquid inlet cavity 12 communicated with the liquid inlet 11 and a sealing cavity 13 not communicated with the liquid inlet 11, part of radiating pipes 21 are communicated with the liquid inlet cavity 12, and the rest radiating pipes 21 are communicated with the sealing cavity 13. The piston member 7 moves within the inlet chamber 1 to adjust the volume of the inlet chamber 12 and to change the number of the radiating pipes 21 communicated with the inlet chamber 12.

According to the arrangement, after the cooling liquid to be cooled enters the radiator from the liquid inlet 11, the cooling liquid flows through the radiator along the liquid inlet cavity 12, the radiating pipe 21 communicated with the liquid inlet cavity 12 and the liquid outlet chamber 3 in sequence so as to radiate the heat. It can be seen that in this process, the heat dissipation pipe 21 communicating with the liquid inlet chamber 12 is the actual heat dissipation element in the heat sink, and the sum of the heat dissipation areas is the effective heat dissipation area of the heat sink. Therefore, when the piston member 7 moves in the liquid inlet chamber 1, the volume of the liquid inlet chamber 12 changes, and the number of the heat dissipation pipes 21 communicated with the liquid inlet chamber 12 changes, the effective heat dissipation area of the heat dissipation device can be adjusted. As a result, under a low-temperature environment, the heat dissipation can be reduced by adjusting the effective heat dissipation area of the heat sink, and the situation that the temperature of the cooling liquid is too low due to too large heat dissipation amount is avoided.

It should be noted that, although the cooling fluid is introduced into the radiating pipes 21 communicating with the sealed chamber 13 when the radiator is initially activated, the cooling fluid is filled in all parts of the radiator including the radiating pipes 21 after the radiator is operated for a certain period of time. At this time, if the cooling liquid to be cooled still flows through the heat dissipation pipe 21 communicated with the sealed cavity 13 and flows out from the heat dissipation pipe, the cooling liquid enters the liquid outlet chamber 3 from the heat dissipation pipe 21 communicated with the liquid inlet chamber 12, and then it is required to dissipate heat and flow out through a route (referred to as a first route) of "the inner cavity of the liquid outlet chamber 3-the heat dissipation pipe 21 communicated with the sealed cavity 13-the heat dissipation pipe 21 communicated with the sealed cavity 13-the inner cavity of the liquid outlet chamber 3-the liquid outlet 31".

Obviously, compared to the path (called the second path) in which the cooling liquid flows out directly through the "inner cavity of the liquid outlet chamber 3 — the liquid outlet port 31", the flow of the cooling liquid in the first path is relatively very slow, substantially close to the blocked state, because the length of the first path is too long compared to the second path. At this time, most of the cooling liquid does not flow through the first route, so the heat dissipation area of the heat dissipation pipe 21 (the heat dissipation pipe 21 communicating with the sealed cavity 13) on the first route can be ignored and is not used as the effective heat dissipation area of the heat sink.

In this embodiment, as shown in fig. 1 and 2, the radiator is vertically arranged as a whole, and a plurality of radiating pipes 21 are arranged at intervals in the vertical direction. When the radiator is placed behind the air inlet grille of the vehicle, the plurality of radiating pipes 21 can be simultaneously contacted with air during the running of the vehicle, and the radiating effect is better. Further, the liquid inlet 11 is disposed at the lower portion of the liquid inlet chamber 1, and the liquid outlet 31 is disposed at the upper portion of the liquid outlet chamber 3. Under the action of the piston member 7, an inlet chamber 12 and a sealing chamber 13 are formed at the lower part and the upper part of the inner cavity of the inlet chamber 1, respectively. Of course, in other embodiments, the heat sink may be disposed horizontally or obliquely according to actual use requirements, and is not limited to this embodiment.

Alternatively, as shown in fig. 6, the radiating pipe 21 is a flat oval pipe, and the cross section of the pipe is a flat oval, so that a larger radiating area can be ensured. Meanwhile, the plurality of radiating pipes 21 are parallel to each other, so the arrangement of the flat elliptical pipes can make the arrangement of the radiating pipes 21 more dense, the number of the radiating pipes is more, and the adjustability of the radiating area is better.

In a specific structure, as shown in fig. 1, the heat sink further includes a driver 4 and a lead screw 6. The screw rod 6 is arranged in the liquid inlet chamber 1 along the arrangement direction of the radiating pipes 21 (namely, the axial direction of the screw rod 6 is consistent with the arrangement direction of the radiating pipes 21), the output end of the driving piece 4 is in transmission connection with the screw rod 6 to drive the screw rod 6 to rotate, and the piston piece 7 is in threaded connection with the screw rod 6. At this time, the driving part 4 drives the screw rod 6 to rotate, so that the piston part 7 can move along the screw rod 6, thereby adjusting the volume of the liquid inlet cavity 12, changing the number of the radiating pipes 21 communicated with the liquid inlet cavity 12 and realizing the adjustment of the effective radiating area of the radiator.

It is understood that the length of the screw shaft 6 should be not less than the arrangement length of the plurality of radiating pipes 21 to enable the maximum adjustment range of the effective radiating area to be obtained when the piston member 7 moves along the screw shaft 6.

Further, as shown in fig. 1, a first bearing 8 and a second bearing 9 are respectively sleeved at two ends of the screw rod 6 to ensure the stability of the rotation of the screw rod 6. Further, for ease of use, a first bearing housing may be provided to mount the first bearing 8, or a second bearing housing may be provided to mount the second bearing 9.

Optionally, as shown in fig. 1 and 3, a limiting protrusion 61 is disposed on the screw rod 6, and the limiting protrusion 61 is configured to abut against the piston member 7 when the piston member 7 moves to the preset position, so as to limit the piston member 7 from moving further, which is more convenient for use. In this embodiment, the limiting protrusion 61 is disposed on the screw rod 6 located in the liquid inlet chamber 12. When the piston member 7 reaches the preset position and abuts against the limiting protrusion 61, the volume of the liquid inlet cavity 12 cannot be reduced, so that a minimum effective heat exchange area can be ensured, and excessive adjustment is avoided. Optionally, the stop protrusion 61 is an annular protrusion. Further, as shown in fig. 1, for the convenience of manufacturing, a portion of the lead screw 6, which cannot be reached by the piston member 7, may be provided as a polish rod due to the restriction of the restricting protrusion 61.

Optionally, as shown in fig. 1, the heat sink further includes a transmission gear 5, the transmission gear 5 includes a driving gear 51 and a driven gear 52 that are in transmission connection, an output end of the driving member 4 is in transmission connection with the driving gear 51 to drive the driving gear 51 to rotate, and the driven gear 52 is fixedly sleeved at one end of the lead screw 6 to drive the lead screw 6 to rotate. When the driving piece 4 runs, the driving piece can drive the screw rod 6 to rotate sequentially through the driving gear 51 and the driven gear 52, the transmission is accurate, and the work is reliable. It will furthermore be appreciated that by presetting the transmission ratio of the transmission gear 5, a rotational speed suitable for the operation of the screw 6 can be provided, avoiding that the screw 6 rotates too fast or too slow. In this embodiment, driving piece 4 and drive gear 5 all set up in feed liquor room 1, and the structure is very compact.

In this embodiment, the driving member 4 is a servo motor, which has high operation precision, strong overload resistance, and low heat and noise. Further, if the piston piece 7 is in the initial position of the piston piece 7 when abutting against the limiting protrusion 61, the displacement of the piston piece 7 after the screw rod 6 rotates for a certain number of turns can be calculated by combining the data such as the rotating speed of the servo motor, the transmission ratio of the transmission gear 5, the screw pitch of the screw rod 6 and the like, so that the real-time position of the piston piece 7 is obtained, and the adjustment is more accurate.

Optionally, as shown in fig. 4, a sealing ring 71 is sleeved on the outer wall of the piston member 7, and the piston member 7 forms a sliding seal with the inner wall of the liquid inlet chamber 1 through the sealing ring 71, so as to prevent the cooling liquid from entering the sealing chamber 13 from the liquid inlet chamber 12. Further, the sealing ring 71 is provided with a plurality of circles of arc-shaped sealing protrusions 711, so that multiple sealing can be formed. Meanwhile, the bulge is arc-shaped, so that a certain guiding effect can be achieved when the sealing ring 71 moves, and the sealing ring 71 can move more smoothly.

In this embodiment, the arc sealing protrusion 711 is provided with two rings to ensure the sealing effect and simplify the manufacturing process. Further, taking the direction shown in fig. 4 as an example, the plurality of radiating pipes 21 are uniformly distributed at intervals along the up-down direction, and the height dimension H of each radiating pipe 21 is the same. The end of the heat pipe 21 connected to the liquid inlet chamber 1 is flush with the inner wall of the liquid inlet chamber 1, so as to facilitate the processing and the smooth movement of the sealing ring 71.

In terms of specific dimensions, as shown in fig. 4 (fig. 4 is a schematic structural view when the piston member 7 moves to the first position), the distance L between the centers of the two arc-shaped sealing protrusions 711 is smaller than the distance D between the two adjacent heat dissipation pipes 21 (i.e., the height of the inner wall of the liquid inlet chamber 1 between the two adjacent heat dissipation pipes 21), so that the two arc-shaped sealing protrusions 711 can stably abut against the inner wall of the liquid inlet chamber 1 to ensure good sealing. Further, as shown in fig. 5 (fig. 5 is a schematic structural view when the piston member 7 moves to the second position), the distance L between the centers of the two arc-shaped sealing protrusions 711 is greater than the height H of the radiating pipe 21, so that when the two arc-shaped sealing protrusions 711 move to the position of the inner cavity of the radiating pipe 21, the arc-shaped sealing protrusions 711 can still be ensured to abut against the inner wall of the fluid inlet chamber 1, and the sealing failure caused by the gap between the arc-shaped sealing protrusions 711 and the end of the radiating pipe 21 can be avoided. Furthermore, it can be understood that, by the above dimension setting, it is ensured that the at least one arc-shaped sealing protrusion 711 abuts against the inner wall of the liquid inlet chamber 1 when the sealing ring 71 moves, thereby ensuring the reliability of the sealing.

In summary, the present embodiment provides a heat sink, which forms the liquid inlet chamber 12 and the sealing chamber 13 by disposing the piston member 7 to separate the liquid inlet chamber 1, so that the cooling liquid to be cooled flows through the heat sink sequentially along the liquid inlet 11, the liquid inlet chamber 12, the heat dissipation pipe 21 communicated with the liquid inlet chamber 12, and the liquid outlet chamber 3, so as to dissipate heat. When the piston member 7 moves in the liquid inlet chamber 1 to change the volume of the liquid inlet chamber 12 and the number of the heat dissipation pipes 21 communicated with the liquid inlet chamber 12, the adjustment of the effective heat dissipation area of the heat sink can be realized. As a result, under a low-temperature environment, the heat dissipation can be reduced by adjusting the effective heat dissipation area of the heat sink, and the situation that the temperature of the cooling liquid is too low due to too large heat dissipation amount is avoided.

The embodiment also provides a vehicle which comprises the radiator and can be used for radiating the cooling liquid of components such as an engine.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
