Detailed Description
In order that the above objects, features and advantages of the application will be readily understood, a more particular description of the application will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. The present application may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the application, whereby the application is not limited to the specific embodiments disclosed below.
As shown in fig. 1, 2 and 3, in one embodiment, a radiator 100 is provided, the radiator 100 is provided with a main liquid inlet 110, a split-flow channel 120, a heat dissipation channel 130, a confluence channel 140 and a main liquid outlet 150, the main liquid inlet 110 is communicated with the split-flow channels 120, the number of the heat dissipation channels 130 is at least two, the split-flow channels 120 are communicated with one end of each heat dissipation channel 130, the other end of each heat dissipation channel 130 is communicated with the confluence channel 140, the confluence channel 140 is communicated with the main liquid outlet 150, and the split-flow channels 120 and the confluence channel 140 are located on the same side of the heat dissipation channels 130 along a first direction (as shown in a direction in fig. 1).
When the radiator 100 in the above embodiment is used, the to-be-radiated member is placed in the outer wall area of the pair of the radiator 100 and the radiating channels 130, and the cooling liquid is input into the diversion channels 120 through the main liquid inlet 110, so that the cooling liquid in the diversion channels 120 is diverted into each radiating channel 130, and then the cooling liquid in each radiating channel 130 can exchange heat with the to-be-radiated member through the radiator 100 at the same time, and the temperature of the cooling liquid in each radiating channel 130 is the same, so that the radiating efficiency and radiating uniformity of the radiator 100 are improved. And the cooling liquid after heat exchange with the heat dissipation part can be converged into the converging channel 140 and discharged through the main liquid outlet 150, so that the convenience of the radiator 100 is improved. In addition, compared with the existing liquid cooling radiator, on the one hand, the split flow channel 120, the radiating channel 130 and the converging channel 140 are integrated in the radiator 100, and the split flow channel 120 and the converging channel 140 are located on the same side of the radiating channel 130, so that the size of the radiator 100 is reduced, and the production cost of the radiator 100 is reduced. On the other hand, the cooling liquid is split and then converged, so that the flowing stroke of the cooling liquid in the radiator 100 is reduced, the resistance of the cooling liquid is reduced, the pressure drop is reduced, and the reliability of the radiator 100 is improved.
The positional relationship between the heat dissipation channels 130 can be flexibly adjusted according to the needs of use. For example, the respective heat dissipation channels 130 can be disposed at intervals in the second direction (as shown in the B direction in fig. 1) or the third direction (as shown in the C direction in fig. 1). The shape and dimensions of the split channel 120, the heat dissipation channel 130 and the converging channel 140 can be flexibly adjusted according to the use requirement. For example, one heat dissipation channel 130 may correspond to one to-be-dissipated heat piece, or a plurality of heat dissipation channels 130 may correspond to one to-be-dissipated heat piece, or one heat dissipation channel 130 may correspond to a plurality of to-be-dissipated heat pieces.
The first direction may be a height direction, a width direction, or a length direction of the heat sink 100. In this embodiment, the first direction is the height direction of the heat sink 100, the second direction is the length direction of the heat sink 100, and the third direction is the width direction of the heat sink 100.
As shown in fig. 2 and 3, further, along the second direction, the main liquid inlet 110 and the main liquid outlet 150 are arranged at intervals, each heat dissipation channel 130 is arranged between the main liquid inlet 110 and the main liquid outlet 150 at intervals, and the dimension of the split channel 120 along the third direction tends to decrease from the side of the split channel 120 close to the main liquid inlet 110 towards the side of the split channel 120 close to the main liquid outlet 150; the dimension of the confluence channel 140 in the third direction tends to decrease from the side of the confluence channel 140 near the main liquid outlet 150 toward the side of the confluence channel 140 near the main liquid inlet 110. In this way, the flow of the cooling liquid in the split channel 120 tends to decrease from the side of the split channel 120 near the main liquid inlet 110 toward the side of the split channel 120 near the main liquid outlet 150, while the fluid cross-sectional area in the split channel 120 tends to decrease, so as to ensure that the pressure of the cooling liquid in the split channel 120 remains stable, and similarly, the flow of the cooling liquid in the converging channel 140 tends to decrease from the side of the converging channel 140 near the main liquid outlet 150 toward the side of the converging channel 140 near the main liquid inlet 110, while the fluid cross-sectional area in the converging channel 140 tends to decrease, so as to ensure that the pressure of the cooling liquid in the converging channel 140 remains stable, and further ensure that the cooling liquid can be more uniformly dispersed in each heat dissipation channel 130, so as to improve the heat dissipation uniformity of the heat sink 100. In other embodiments, the dimensions of the split channel 120 and the converging channel 140 along the third direction can be flexibly adjusted according to the actual use requirement. For example, from the side of the confluence channel 140 near the main liquid outlet 150 toward the side of the confluence channel 140 near the main liquid inlet 110, the size of the diversion channel 120 in the third direction increases first and then decreases or decreases first and then increases. In this way, the cooling liquid in each cooling channel 130 is unevenly distributed, thereby meeting the cooling requirements of different parts to be cooled and improving the adaptability of the radiator 100.
The dimension of the split channel 120 along the third direction tends to decrease from the side of the split channel 120 near the main liquid inlet 110 toward the side of the split channel 120 near the main liquid outlet 150, which may be linear or nonlinear. The dimension of the converging channel 140 in the third direction tends to decrease from the side of the converging channel 140 near the main liquid outlet 150 toward the side of the converging channel 140 near the main liquid inlet 110, which may be linear or non-linear.
As shown in fig. 2, alternatively, the inner side wall of the side of the flow dividing channel 120 away from the flow converging channel 140 and the inner side wall of the side of the flow converging channel 140 away from the flow dividing channel 120 are disposed along the second direction. In this way, the inner side wall of the side where the split flow channel 120 and the converging channel 140 are close to each other can be correspondingly inclined, so that the split flow channel 120 and the converging channel 140 can be enclosed to be rectangular, the volume of the radiator 100 is further reduced, and the production cost of the radiator 100 is reduced.
As shown in fig. 2, alternatively, two adjacent inner side walls of the diversion channel 120 are in transitional connection through a first cambered surface 121. In this way, the first cambered surface 121 can guide the cooling liquid, so that the cooling liquid can smoothly flow at the corners in the diversion channels 120, the phenomenon that the cooling liquid forms vortex at the corners of the diversion channels 120 to influence the cooling liquid distribution in each cooling channel 130 is avoided, and the reliability of the radiator 100 is improved.
As shown in fig. 2, alternatively, two adjacent inner side walls of the converging channel 140 are in transitional connection through a second cambered surface 141. In this way, the second cambered surface 141 can guide the cooling liquid, so that the cooling liquid can smoothly flow at the corners in the converging channel 140, the cooling liquid is prevented from forming vortex at the corners of the converging channel 140 to influence the cooling liquid distribution in each cooling channel 130, and the reliability of the radiator 100 is improved.
As shown in fig. 2 and 3, in one embodiment, along the second direction, the main liquid inlet 110 and the main liquid outlet 150 are disposed at intervals, each heat dissipation channel 130 is disposed between the main liquid inlet 110 and the main liquid outlet 150 at intervals, one end of each heat dissipation channel 130, which is close to the split channel 120, is provided with a split liquid inlet 131 communicated with the split channel 120, and the inner diameter of each split liquid inlet 131 tends to increase from the main liquid inlet 110 toward the main liquid outlet 150. In this way, the flow rate of the cooling liquid in the split flow channels 120 tends to decrease from the main liquid inlet 110 toward the main liquid outlet 150, and the inner diameter of each split flow inlet 131 tends to increase, so that the flow rate of the cooling liquid entering each heat dissipation channel 130 is kept uniform, and the heat dissipation uniformity of the heat sink 100 is improved.
The heat sink 100 may be formed by integrally forming the heat sink in the direction of the heat sink, or may be formed by assembling the heat sink in the direction of the heat sink.
As shown in fig. 2 and 3, in one embodiment, the heat sink 100 includes a branch-and-confluence member 160, a sealing member 170, and a first heat sink member 180; the branch converging piece 160 is provided with a main liquid inlet 110, a flow dividing groove 122, a heat dissipation groove 133, a converging groove 142 and a main liquid outlet 150, the converging groove 142 and the flow dividing groove 122 are arranged on one side of the branch converging piece 160 at intervals, the heat dissipation grooves 133 are at least two, each heat dissipation groove 133 is arranged on one side of the branch converging piece 160 far away from the flow dividing groove 122 at intervals, the sealing piece 170 is arranged on one side of the branch converging piece 160 near the flow dividing groove 122, so that the sealing piece 170 can be matched with the inner wall of the flow dividing groove 122 to form a flow dividing channel 120, the sealing piece 170 can be matched with the inner wall of the converging groove 142 to form a converging channel 140, and the first heat dissipation piece 180 is arranged on one side of the branch converging piece 160 near the heat dissipation groove 133, so that the first heat dissipation piece 180 can be matched with the inner wall of the heat dissipation groove 133 to form a heat dissipation channel 130. In this way, the radiator 100 may be assembled into a whole after the sealing member 170, the branch and confluence member 160 and the first heat dissipation member 180 are respectively processed, thereby improving the convenience of the processing of the radiator 100.
Wherein the seal 170 may be a sealing plate, a sealing sheet, or other sealing structure. The branch-converging member 160 may be a branch-converging plate, a branch-converging block, or other branch-converging structure. The first heat sink 180 may be a heat sink, or other heat dissipating structure.
As shown in fig. 2, 3 and 4, further, a second heat dissipation member 190 is disposed on a side of the first heat dissipation member 180 adjacent to the branch/collector member 160, and the second heat dissipation member 190 is disposed corresponding to the heat dissipation groove 133. In this way, the second heat dissipation element 190 can be correspondingly located in the heat dissipation channel 130, so that the first heat dissipation element 180 and the second heat dissipation element 190 can be in contact with the cooling liquid, the contact area between the heat sink 100 and the cooling liquid is increased, the cooling liquid is ensured to be capable of sufficiently exchanging heat with the heat dissipation element to be dissipated, and the heat dissipation efficiency and reliability of the heat sink 100 are improved.
As shown in fig. 2 and 4, optionally, each heat dissipation groove 133 is correspondingly provided with at least two second heat dissipation elements 190, and at least two second heat dissipation elements 190 are disposed along the extending direction of the heat dissipation groove 133. In this way, the area, corresponding to the second heat dissipation element 190, on the side, away from the branch and converging element 160, of the first heat dissipation element 180 can be set to be the heat dissipation element alone, so that each heat dissipation channel 130 can dissipate heat of at least two heat dissipation elements simultaneously, and the applicability and heat dissipation efficiency of the heat sink 100 are improved.
The second heat sink 190 may be a pin-fin (pin fin) heat sink structure, a heat sink fin, or the like. The number of the second heat dissipation elements 190 can be flexibly adjusted according to the actual use requirement. In particular, in the present embodiment, the number of the second heat dissipation elements 190 is twice the number of the heat dissipation channels 130, and each of the second heat dissipation elements 190 includes at least two heat dissipation fins.
As shown in fig. 2 and 4, alternatively, the main liquid inlet 110 and the main liquid outlet 150 are both located at one side of the branch and collector 160 near the first heat sink 180, the first heat sink 180 is provided with a liquid inlet through hole 181 and a liquid outlet through hole 182, the liquid inlet through hole 181 is correspondingly communicated with the main liquid inlet 110, and the liquid outlet through hole 182 is correspondingly communicated with the main liquid outlet 150.
