Description

Technical Field

[0001] The utility model relates to the technical field of radiators, and particularly relates to a water radiator and a water-cooled radiator using a blower. Background Art

[0002] With the rapid development of technologies such as machinery, microelectronics, and computers, chips have played an increasingly important role in daily production and life. When a chip is working, it will generate a large amount of heat. Excessive temperature will affect the working performance of the chip, so it is necessary to dissipate heat from the chip.

[0003] At present, the mature heat dissipation means include two types: air cooling and liquid cooling. The chip liquid-cooled radiator has the advantages of being quiet, having stable temperature reduction, and having little dependence on the environment. The traditional liquid-cooled radiator consists of three parts: a cold head, a cold radiator, and a fan. Among them, the cold head is directly in contact with the chip and is responsible for absorbing the heat emitted by the chip. The water pump in the cold head is responsible for providing the power for the coolant to flow. After the coolant absorbs heat in the cold head, it flows into the cold radiator through the water pipe under the action of the water pump; the cold radiator is installed in the chassis and is responsible for dissipating the heat absorbed by the cold liquid outside the chassis. After the coolant is cooled in the cold radiator, it then flows back to the cold head through the water pipe, and this cycle continues; the fan is installed on the cold radiator and is responsible for accelerating the air flow speed in the cold radiator and improving the heat dissipation efficiency.

[0004] However, the existing water-cooled radiator products usually have the following problems: 1. When the water radiator is used with an ordinary fan, since the air outlet of the ordinary fan does not blow air straight out but is a spiral air flow, it causes the air duct in the chassis to be disordered, and the overall heat dissipation efficiency of the chassis decreases; 2. The water radiator generally needs to be used in combination with a dust-proof net, resulting in it being difficult for the water radiator to be blown through. The existing solution is to increase the number of fans, but the cost is high.

[0005] Therefore, the present application provides a water radiator and a water-cooled radiator using a blower to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a water radiator and a water-cooled radiator using a blower for the defects and deficiencies in the prior art.

[0007] The technical solution adopted by the utility model is: a water radiator using a blower, which includes a water radiator body and a blower arranged on the water radiator body. The blowing surface of the blower faces the water radiator body, and the blower is fixedly arranged on one side of the water radiator body;

[0008] The blower includes a housing with an accommodation space, at least one set of impeller assemblies, and at least one set of drive motors.

[0009] Optionally, the impeller assembly includes a plurality of blades arranged along the length direction of the housing and a plurality of annular plates evenly arranged along the length direction of the blades. The cross-section of the blade is arc-shaped. Through holes for the blades to pass through are formed in the annular plates, and the through holes are evenly distributed along the circumferential direction of the annular plates. After the output shaft of the driving motor extends into the housing, it is fixedly connected to one of the annular plates.

[0010] Optionally, the number of both the impeller assembly and the driving motor is two groups. The two groups of impeller assemblies are both arranged along the length direction of the housing. The two groups of impeller assemblies are symmetrically arranged on the upper and lower sides inside the housing, and the blade directions in the two groups of impeller assemblies are opposite. The two groups of driving motors are both fixed on one side of the housing, and the two groups of driving motors are respectively used to drive the two groups of impeller assemblies to rotate.

[0011] Optionally, a partition plate is arranged between the two groups of impeller assemblies. The two ends of the partition plate are respectively fixedly connected to the two ends of the housing. The partition plate includes two arc-shaped plates arranged oppositely. The two arc-shaped plates respectively form a first flat part, a first arc part, a second arc part, and a second flat part in sequence from the air inlet towards the air outlet to cooperate with guiding the air flow.

[0012] Optionally, the housing includes a left support plate and a right support plate arranged oppositely, and an upper housing and a lower housing arranged between the left support plate and the right support plate. The two ends of the impeller assembly are respectively rotatably connected to the left support plate and the right support plate. Both the upper housing and the lower housing are arc-shaped, and the concave parts of the upper housing and the lower housing are arranged oppositely.

[0013] Optionally, the water discharge body includes a frame, water chambers symmetrically arranged on both sides of the frame, a plurality of water channels arranged between the two water chambers, and a heat sink group arranged between adjacent two water channels. The water chamber has a chamber for accommodating the coolant inside. The plurality of water channels are evenly distributed between the two water chambers, and the plurality of water channels are all communicated with the water chambers so that the coolant in one of the water chambers can flow into the other water chamber through the water channels.

[0014] Optionally, the heat sink group includes a plurality of heat sink fins connected in sequence. The heat sink fins are V-shaped, and the top and bottom of the heat sink fins are both in contact with the water channels.

Detailed implementation manners

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying Figures 1-6 drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] It should be noted that the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "back", "side", "circumferential" and the like of the present utility model indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model. In addition, the terms such as "first" and "second" are only used to distinguish multiple components or structures with the same or similar structures, and do not represent a special limitation on the setting order or connection relationship.

[0029] This embodiment relates to a water pump using a blower. Referring to Figures 1-6 FIG. [not provided in the original, assume it's a figure number], it includes a water pump body 10 and a blower 20 arranged on the water pump body 10. The blowing surface of the blower 20 faces the water pump body 10, and the blower 20 is fixedly arranged on one side of the water pump body 10.

[0030] The blower 20 includes a housing 21 having an accommodation space, at least one set of impeller assemblies 22, and at least one set of drive motors 23. The housing 21 is arranged along the length direction of the water pump body 10. An air inlet and an air outlet are respectively formed on both sides of the housing 21. Both ends of the impeller assembly 22 are rotatably connected to both ends of the housing 21. The drive motor 23 is arranged on one side of the housing 21, and the output shaft of the drive motor 23 is fixedly connected to the impeller assembly 22 to drive the impeller assembly 22 to rotate.

[0031] It can be understood that by driving the impeller assembly 22 to rotate through the drive motor 23, when the impeller assembly 22 rotates, the air flow enters the interior of the impeller assembly 22 from the air inlet of the housing 21 and is discharged from the other side of the impeller assembly 22, so that the air flow blows towards the water radiator body 10 from the air outlet. Compared with the cooperation of an ordinary fan and the water radiator body 10, in this embodiment, the blower 20 is used instead of an ordinary fan, which can generate an air flow with a larger air volume, and it is easier to blow through the water radiator body 10, thereby accelerating the air flow inside the water radiator body 10, improving the heat dissipation efficiency. Moreover, after the air flow with a large air volume blows through the water radiator body 10, it can guide the air duct inside the chassis, making the air duct inside the chassis regular, and further improving the heat dissipation efficiency.

[0032] Further, the impeller assembly 22 includes a plurality of blades 221 arranged along the length direction of the housing 21 and a plurality of annular plates 222 uniformly arranged along the length direction of the blades 221. The cross-section of the blade 221 is arc-shaped. Through holes for the blades 221 to pass through are formed in the arc-shaped plate 241, and the through holes are uniformly distributed along the circumferential direction of the annular plate 222. And the output shaft of the drive motor 23 extends into the housing 21 and is fixedly connected to one of the annular plates 222. It should be noted that after the output shaft of the drive motor 23 extends into the housing 21, it is fixedly connected to the outermost annular plate 222, and the end of the blade 221 away from the drive motor 23 is rotatably connected to the inner wall of the housing 21.

[0033] It can be understood that by forming a plurality of through holes for the blades 221 to pass through in the arc-shaped plate 241, a plurality of blades 221 can cooperate to form a long cylindrical shape, so that when the drive motor 23 drives the outermost annular plate 222 to rotate, the blades 221 are driven to rotate, thereby generating an air flow with a large air volume.

[0034] Further, the number of both the impeller assembly 22 and the drive motor 23 is two groups. The two groups of impeller assemblies 22 are both arranged along the length direction of the housing 21. The two groups of impeller assemblies 22 are symmetrically arranged on the upper and lower sides inside the housing 21, and the directions of the blades 221 of the two groups of impeller assemblies 22 are opposite. The two groups of drive motors 23 are both fixedly installed on the same side of the housing 21, and the two groups of drive motors 23 are respectively used to drive the two groups of impeller assemblies 22 to rotate.

[0035] It can be understood that through the arrangement of the two groups of impeller assemblies 22 and the two groups of drive motors 23, an air flow with a larger air volume can be generated, further accelerating the air flow inside the water radiator body 10, and the structure is compact. While achieving a larger air volume, the volume of the entire blower 20 will not be increased. Compared with using an ordinary fan to blow the water radiator body 10, this embodiment can generate an air flow with a larger air volume at low cost and low space occupation, thereby improving the heat dissipation efficiency.

[0036] Further, a partition plate 24 is provided between the two groups of impeller assemblies 22. The partition plate 24 is arranged along the length direction of the housing 21, and both ends of the partition plate 24 are fixedly connected to both ends of the housing 21 respectively. The partition plate 24 includes two arc-shaped plates 241 arranged oppositely. The two arc-shaped plates 241 are successively formed with a first flat portion 2411, a first arc portion 2412, a second arc portion 2413, and a second flat portion 2414 from the air inlet towards the air outlet direction to cooperate with guiding the air flow so that the air flows generated by the two groups of impeller assemblies 22 will not interfere with each other.

[0037] It can be understood that through the arrangement of the partition plate 24, when the two groups of drive motors 23 drive the two groups of impeller assemblies 22 to rotate, the air flows generated by the rotation of the two groups of impeller assemblies 22 will not interfere with each other at the air outlet, thereby avoiding the situation of wind loss caused by the interference of the two groups of air flows, and further ensuring the heat dissipation efficiency.

[0038] Further, the housing 21 includes a left support plate 211 and a right support plate 212 arranged oppositely, and an upper housing 213 and a lower housing 214 arranged between the left support plate 211 and the right support plate 212. Both ends of the impeller assembly 22 are rotatably connected to the left support plate 211 and the right support plate 212 respectively. The upper housing 213 and the lower housing 214 are both arranged in an arc shape, and the recessed portions of the upper housing 213 and the lower housing 214 are arranged oppositely.

[0039] It can be understood that through the cooperation between the left support plate 211, the right support plate 212, the upper housing 213, and the lower housing 214, a whole and stable housing 21 is formed, enabling the impeller assembly 22 to rotate stably within the housing 21. At the same time, the arc-shaped upper housing 213 and lower housing 214 can better guide the air flow inside, thereby ensuring the stability of the air flow blown out from the air outlet.

[0040] Further, the water discharge body 10 includes a frame 11, water chambers 12 symmetrically arranged on both sides of the frame 11, a plurality of water channels 13 arranged between the two water chambers 12, and a heat sink group arranged between adjacent two water channels 13. Among them, both of the two water chambers 12 have chambers for accommodating the coolant. The plurality of water channels 13 are evenly distributed between the two water chambers 12, and the plurality of water channels 13 are all communicated with the water chambers 12 so that one of the water chambers 12 can flow into the other water chamber 12 through the water channels 13.

[0041] It can be understood that through the arrangement of the water chambers 12, the water channels 13, and the heat sink group, when working, the air flow generated by the impeller assembly 22 blows into the heat sink group from the air outlet, accelerating the air flow inside the heat sink group, thereby being able to dissipate the heat in the coolant faster and improving the heat dissipation efficiency.

[0042] Furthermore, the heat sink group includes a plurality of heat dissipation fins 14 connected in sequence. The heat dissipation fins 14 are arranged in a V shape, and both the top and bottom of the heat dissipation fins 14 are in contact with the water channel 13.

[0043] It can be understood that a plurality of V-shaped heat dissipation fins 14 connected in sequence are arranged between two adjacent water channels 13. The contact area between the heat dissipation fins 14 and the water channel 13 is relatively large, enabling the heat of the coolant to be evenly transferred to the heat dissipation fins 14 when the coolant enters the water chamber 12 through the water channel 13. At the same time, the gaps existing in the V-shaped heat dissipation fins 14 are more conducive to heat dissipation, thereby improving the heat dissipation efficiency.

[0044] Further, a fan 20 fixing plate 15 is provided on the water radiator body 10. A positioning hole 151 is opened on the fan 20 fixing plate 15, and a mounting hole 215 corresponding to the positioning hole 151 is opened on the housing 21.

[0045] Through the cooperation among the fan fixing plate 15, the positioning hole 151, and the mounting hole 215, the fan 20 can be fixed to the side wall of the water radiator body 10, so that the fan 20 can stably blow air to the water radiator body 10, ensuring the heat dissipation efficiency.

[0046] In addition, this embodiment further provides a water-cooled radiator, which includes a cold head assembly 30, the above-described water radiator with a fan 20, and a pipe assembly 40 for connecting the cold head assembly 30 and the water radiator body 10. Among them, the cold head assembly 30 includes an integrally formed water-cooling block and a water pump. The water-cooling block is used to contact the chip to absorb the heat generated by the chip during operation, and a water-cooling cavity for accommodating the water-cooling liquid is provided inside the water-cooling block. The pipe assembly 40 includes a liquid inlet pipe 41 and a liquid return pipe 42. Both ends of the liquid inlet pipe 41 and the liquid return pipe 42 are connected to the water chamber 12 and the water-cooling block. The water pump is used to transport the water-cooling liquid in the water-cooling cavity to the water chamber 12 through the liquid inlet pipe 41 and then send the water-cooling liquid back to the water-cooling cavity through the liquid return pipe 42 to realize the recycling of the water-cooling liquid.

[0047] During use, the water-cooling block absorbs the heat generated by the chip operation and transfers the heat to the water-cooling liquid inside it. At this time, under the action of the water pump, the water-cooling liquid flows into the water chamber 12 through the liquid inlet pipe 41 and then enters the water channel 13. The heat carried by the water-cooling liquid is transferred from the water channel 13 to the heat dissipation fins 14 when passing through the water channel 13. At this time, the impeller assembly 22 is driven to rotate by the driving motor 23, so that the impeller assembly 22 generates an air flow with a large air volume and blows it towards the heat sink group on the water radiator body 10, accelerating the air flow between the heat dissipation fins 14 in the heat sink group, thereby dissipating the heat of the cooling liquid in the water channel 13, that is, reducing the temperature of the cooling liquid in the water radiator body 10. At this time, the cooling liquid in the water chamber 12 is sent back into the water-cooling block 31 through the liquid return pipe 42, realizing the recycling of the water-cooling liquid, and thus realizing the continuous heat dissipation of the chip. At the same time, since the air flow volume generated by the impeller assembly 22 is large, it can blow through the water radiator body 10 and can guide the air duct in the chassis, making the air duct air flow in the chassis regular, and further improving the heat dissipation efficiency.

[0048] The above is only used to illustrate the technical solution of the present invention rather than to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention shall be covered by the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
