The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
A heat dissipation device comprises a heat dissipation pipe, a first liquid collection pipe, a second liquid collection pipe, at least one piston arranged in the first liquid collection pipe and/or the second liquid collection pipe, and a piston driving device for driving the piston to move; the first liquid collecting pipe is communicated with the second liquid collecting pipe through a plurality of radiating pipes; the first liquid collecting pipe is provided with at least one liquid inlet, the second liquid collecting pipe is provided with at least one liquid outlet, and the total number of the liquid inlets and the liquid outlets is not less than 3; the piston driving means is capable of driving the piston to move inside the first header pipe and/or the second header pipe, thereby separating the first header pipe and/or the second header pipe into separate pipe sections.
As described above, the heat sink of the present invention includes the piston, and the flow rate of the coolant of each cooling circuit can be adjusted by adjusting the piston. Specifically, a plurality of holes are distributed on the first liquid collecting pipe and the second liquid collecting pipe, each hole is communicated with one end of the corresponding radiating pipe, a liquid inlet is formed in the first liquid collecting pipe, a liquid outlet is formed in the second liquid collecting pipe, recommended positions of the liquid inlets are near two ends of the first liquid collecting pipe, and similarly, the liquid outlets are also the same; a piston is arranged in the first liquid collecting pipe and/or the second liquid collecting pipe, and the outer surface of the piston is matched with the inner surface of the first liquid collecting pipe or the second liquid collecting pipe, so that the fluid in the first liquid collecting pipe or the second liquid collecting pipe is isolated; the piston may be movable inside the first header pipe and/or the second header pipe by the piston driving means.
Specifically, the following technical schemes are mainly adopted:
the number of the liquid inlets is 1, the number of the liquid outlets is 2, and a piston is arranged between the two liquid outlets;
the number of the liquid inlets is 2, the number of the liquid outlets is 1, and a piston is arranged between the two liquid inlets;
the number of the liquid inlets and the liquid outlets is 2, and a piston is arranged between every two liquid inlets and every two liquid outlets.
These schemes will be described in detail later by specific embodiments.
In a further aspect, the number of at least one of the liquid inlets or the liquid outlets is greater than or equal to 3, in this case, a piston may be respectively disposed between every two adjacent liquid outlets or every two adjacent liquid inlets, so as to divide the heat dissipation apparatus into more independent working sections for concentrated heat dissipation of more heat generating devices. In addition, the sectional shape of the inner surface of the header pipe is not particularly limited, but in the present invention, the sectional shape of the inner surface of the header pipe as a whole assumes a circular shape. The circular tube is mainly used for conveying water, gas, oil and other general low-pressure fluids, is also used as an oil well tube, an oil conveying tube and the like of the petroleum industry, particularly a marine oil field, and also accords with the flexible arrangement design. Furthermore, the radiating pipe in the invention adopts the flat pipe, the single pipe of the flat pipe has small thickness, compact size and small occupied area, and the installation space can be saved.
In the invention, the position of the piston in the first liquid collecting pipe and/or the second liquid collecting pipe can be adjusted, so that when a certain loop requires large heat dissipation capacity and another loop requires small heat dissipation capacity, the number of the heat dissipation pipes of the loop requiring large heat dissipation capacity can be increased by adjusting the position of the piston, and the effect of free heat dissipation of the heat dissipation device to different loops is realized. In addition, because the quantity of the radiating pipes can be adjusted, the pressure loss of the loop can be reduced, and the flow of the loop can be increased due to the pressure loss reduction, so that the radiating capacity of the loop is further increased.
The embodiments of the present invention will be described in detail below with reference to a radiator in an automobile as an example.
Generally, the heat dissipation of a heating element in an automobile has peaks and valleys, and the peaks and valleys of the heat dissipation of the heating element are different. The structure of the existing radiator is fixed, so the performance of the radiator for radiating the heat of the cooling circuit of the heating element is not changed no matter how the required radiating capacity of the heating element is changed; therefore, to ensure the proper operation of the heat generating component, the design is usually matched with a radiator with corresponding performance for each loop according to the maximum heat dissipation requirement of the loop.
Thus, the prior art heat sink solution causes the following problems: in the use process, the heat dissipation capacity of the radiator in the first loop is insufficient, and the heat dissipation capacity of the radiator in the second loop is more surplus; when the heat dissipation capacity of the second loop radiator is insufficient, the heat dissipation capacity of the first loop radiator is more surplus; that is, although the total heat dissipation capacity is redundant, the heat dissipation performance of each circuit is insufficient. In order to meet the heat dissipation requirements of the heating elements in the loops, the radiators in the loops are respectively matched with the radiators according to the maximum heat dissipation requirement of the loops, so that the total mass and volume of the radiators become very large, and the arrangement difficulty, the manufacturing cost and the dynamic property and the economical efficiency of automobile products are negatively influenced.
The heat dissipation device provided by the invention can realize that the whole heat dissipation device can adjust the flow of the cooling liquid of each cooling circuit by adjusting the position of the piston in the first liquid collecting pipe and/or the second liquid collecting pipe. Therefore, under the condition of ensuring that the heat dissipation performance of each loop is met, the weight and the volume of the radiator are reduced by reducing the total heat exchange capacity of the radiator, the arrangement difficulty and the manufacturing cost are finally reduced, and the use performance of the product is improved.
Referring to fig. 1 to 7, a heat dissipation device, a heat dissipation system and an automobile according to the present invention are described.

As shown in fig. 3, two ends of the first liquid collecting pipe 121 are respectively provided with one liquid inlet 1211, two ends of the second liquid collecting pipe 122 are respectively provided with one liquid outlet 1222, the first liquid collecting pipe 121 and the second liquid collecting pipe 122 are respectively provided with a piston 13, a piston driving device for driving the piston 13 to move is further provided, and the piston 13 moves between the two liquid inlets 1211 and the two liquid outlets 1222.

Therefore, in all the embodiments described above, the present embodiment is the most preferred embodiment. The radiators of all loops are integrated into one radiator, and the performance that all cooling loops share the whole radiator is realized, so that the defects of large weight and size, high arrangement difficulty and cost and low product use performance of the conventional radiator technical scheme are overcome.
Utilize position adjustable piston 13, realize the free distribution of 11 figure of each return circuit cooling tubes, thereby realize that whole heat abstractor can adjust the flow of each cooling circuit's coolant liquid, and realize the free regulation of each return circuit pressure loss, thereby reasonable efficient has utilized whole heat abstractor's heat dispersion, realized when certain return circuit heat dissipation demand is high and certain return circuit heat dissipation demand is low, through adjusting piston 13 the position alright realize the adjustment of heat-sinking capability between each return circuit, current radiator performance inequality has been avoided, and the problem of unable coordination, and current radiator need realize the problem of flow control in the return circuit with the help of extra choke valve.
Further, the two pistons 13 move synchronously.
It should be noted that, when the two pistons 13 move synchronously, the internal fluid in the whole heat dissipation device can be divided into two parts to form two independent and adjustable heat dissipation areas, so as to ensure the heat dissipation effect.
Specifically, as shown in fig. 4 to 7, the heat dissipating device 1 further includes a heat dissipating fin 15, and the heat dissipating fin 15 is in contact with the outer sides of two adjacent heat dissipating pipes 11.
It should be noted that the heat dissipation speed can be increased by using the heat dissipation fins 15, and therefore, the present invention employs heat dissipation fins. The contact area of the radiating fins and the air is large, and therefore more heat can be taken away.
Further, the fitting length of the piston 13 and the first header pipe 121 or the second header pipe 122 in the moving direction of the piston 13 is greater than the length of the radiating pipe 11 in the moving direction of the piston 13 and is less than the distance between two adjacent radiating pipes 11 in the moving direction of the piston 13.
In this embodiment, the size of the piston 13 is determined by the width of the radiating pipe 11 and the interval between two adjacent radiating pipes 11, and when the piston 13 satisfies the above requirements, the fluid in the first header pipe 121 and/or the second header pipe 122 can be better isolated, thereby improving the radiating performance of each cooling circuit.
The fluid in the first header 121 and/or the second header 122 can be better isolated by three conditions: the fluid in the first header 121 can be better isolated; the fluid in the second header 122 can be better isolated; and the fluid in the first header 121 and the second header 122 can be better isolated.

The sealing ring 16 is arranged at the joint of the screw rod 141 and the first liquid collecting pipe 121 or the joint of the screw rod 141 and the second liquid collecting pipe 122, and the sealing performance of the first liquid collecting pipe 121 or the second liquid collecting pipe 122 can be ensured by using the sealing ring 16, so that the heat dissipation effect is improved.
As described above, a speed reducer, a coupling, or the like may be added between the motor and the screw 141. The liquid collecting pipe is provided with a groove 123, and the shape of the groove 123 is not limited, and may be straight or spiral in the direction opposite to the spiral direction of the screw rod 141. The groove 123 primarily restricts the rotational movement of the piston 13, thereby converting the rotational movement of the piston 13 into linear movement of the piston 13.
The piston driving device may be driven by a flexible body such as a rope. Furthermore, besides the above solutions, a limit block may be disposed on the piston 13 to limit the rotation of the piston 13, that is, the solutions that can limit the rotation of the piston 13 may be applied to the present invention, and therefore, the details are not repeated herein.
