Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology, and in particular to a split-type water-cooled radiator. Background Technology

[0002] With the continuous improvement of the computing power of electronic components, especially high-performance processors (such as CPUs), their heat generation has increased significantly, placing higher demands on the performance of heat dissipation systems. Liquid cooling radiators use a motor to circulate the coolant in the cavity and pipes. The heat absorbed by the water block is carried by the coolant to the radiator (also known as the radiator coil) and then blown out of the chassis by a fan, achieving the effect of heat dissipation.

[0003] Existing all-in-one water cooling radiators typically integrate the water block and water pump into the same cavity, which has obvious technical defects. First, since the water block is in direct contact with the CPU heat source, the high temperature of its heat exchange area will be quickly conducted to the adjacent water pump motor, causing the motor to operate at high temperatures for a long time. This can easily lead to aging of the internal components of the water pump and shorten its lifespan. Second, traditional water blocks generally use a copper base and plastic top cover with screw locking and O-ring sealing structure. The O-ring material is prone to aging, embrittlement and deformation under long-term thermal expansion and contraction. After the sealing performance deteriorates, it is easy to cause coolant leakage, which is not conducive to the long-term safe operation of the equipment.

[0004] Therefore, we propose a split-type water-cooled radiator to solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a split-type water-cooled radiator.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a split-type water-cooled radiator, including a radiator, hoses, and a water-cooling head. The water-cooling head has an open chamber, and the heat exchange fins are fixedly installed at the bottom of the inner wall of the chamber and close the opening. A water outlet communicating with the chamber is provided on one side of the water-cooling head. A water pump is provided above the water-cooling head, and the outlet of the water pump is connected to the inlet of the chamber. The radiator is connected to the water-cooling head and the water pump respectively through hoses.

[0007] The heat exchange fins exchange heat with the CPU body. The water pump drives the coolant to flow. The coolant enters the chamber through the water pump outlet and flows through the heat exchange fins to flush the folded fins and remove heat. The hot liquid that absorbs heat flows into the radiator through the outlet of the water cooling head. The radiator releases the heat to the external environment. The cooled liquid then returns from the radiator to the water pump inlet and enters the water cooling head, circulating and absorbing heat for heat exchange.

[0008] Preferably, the water pump is fixedly mounted on the upper surface of the water cooling head via a pump plate, and support legs are fixedly mounted at the four corners of the pump plate, with mounting holes provided on the support legs.

[0009] Preferably, the inlet of the water pump is connected to the outlet of the radiator via a hose, and the outlet of the water cooling head is connected to the inlet of the radiator via a hose.

[0010] Preferably, the inlet head of the water pump is located above the outlet head.

[0011] Preferably, the upper surface of the heat exchange fin is provided with folded FIN sheets. The FIN sheets are multi-layered sheet structures arranged in a wave-like pattern to increase the heat exchange area and improve the heat dissipation effect.

[0012] Preferably, the heat exchange fins seal the opening of the chamber through friction welding, eliminating the need for traditional O-ring seals and screws, thereby improving sealing performance and reducing the risk of coolant leakage.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model of a split water-cooled radiator places the water pump on the upper part of the water cooling head and adopts a split connection method, so that the high temperature of the CPU will not be directly transferred to the water pump motor. At the same time, the coolant is cooled by the radiator after flowing through the water cooling head and then enters the water pump. The structure and flow direction achieve thermal isolation of the water pump, effectively reducing the operating temperature of the water pump and improving its service life and operational stability.

[0015] The heat exchange fins seal the opening of the chamber through friction welding, eliminating the need for traditional O-ring and screw sealing structures. This fundamentally avoids coolant leakage caused by aging of the seals, improving the overall sealing performance and reliability of the device.

[0016] The top cover of the water cooling head is made of metal, which has good thermal conductivity and can be used as an auxiliary heat dissipation path to further reduce thermal resistance. At the same time, the heat exchange fins used have a multi-layer plate-shaped wave structure, which significantly increases the heat exchange area, improves the heat exchange efficiency between the liquid and the metal surface, and enhances the heat dissipation performance.

[0017] Each functional component, such as the water pump, water cooling head, and radiator, has good modular independence, which facilitates later replacement and maintenance. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] like Figures 1-4 As shown, the present invention proposes a split-type water-cooled radiator, including a radiator 1, a CPU body 3, a water block 4, a water pump 5, a pump plate 6, and a connecting hose 2. The device adopts a modular structure design, and the components are connected by the hose 2. The device as a whole adopts a split and modular structure design, with each major component arranged independently and flexibly connected by the hose 2 to form a cooling circuit. It has good installation adaptability. The coolant circulates between the above components to form an efficient closed-loop heat dissipation path, realizing stable and efficient heat transfer and release for the CPU body 3.

[0027] The water cooling head 4 mainly consists of a water outlet 401, a chamber 402, and a heat exchange fin 403. The chamber 402 is located inside the water cooling head 4, and the heat exchange fin 403 is fixedly installed on its bottom inner wall. The heat exchange fin 403 is connected to the inner wall of the chamber 402 by friction welding. The heat exchange fin 403 and the water outlet 401 form a friction weld connection structure, eliminating O-rings and screws and other sealing components, significantly improving the sealing performance of the water cooling head 4 and reducing the risk of coolant leakage. The heat exchange fin 403 is integrated with the chamber 402 by friction welding, which greatly improves the sealing performance of the water cooling head 4 from a structural level and avoids coolant leakage problems caused by aging of sealing components.

[0028] The water outlet 401 is fixedly installed at the upper outlet of the chamber 402 to guide the hot liquid out. The heat exchange fin 403 is in direct contact with the CPU body 3 to absorb the heat generated by the CPU and transfer it to the circulating coolant. The upper surface of the heat exchange fin 403 is provided with folded fins made of aluminum material. The folded fins are arranged in a multi-layered, wave-like pattern, which effectively increases the heat exchange area and improves the cooling efficiency. The heat exchange fin 403 is made of aluminum material with high thermal conductivity. The surface is designed as a multi-layered, wave-like pattern, which not only improves the liquid turbulence effect but also significantly increases the heat exchange area, thereby effectively improving the heat exchange capacity per unit volume.

[0029] Example 2

[0030] like Figures 1-4 As shown, the present invention proposes a split-type water-cooled radiator. Compared with Embodiment 1, this embodiment further includes: a water pump 5 is fixedly mounted above the water cooling head 4 via a pump plate 6. The pump plate 6 has four support legs 601 at its four corners, and the support legs 601 have mounting holes 602 to facilitate the fixed installation of the whole unit with the motherboard or heat dissipation bracket. The outlet of the water pump 5 is connected to the inlet of the chamber 402, so that it drives the coolant to be injected into the water cooling head 4 from top to bottom, effectively flushing the heat exchange fins 403 and removing heat.

[0031] After the high-temperature liquid flows out through the outlet 401, it enters the radiator 1 through the hose 2. The radiator 1 is used to release the heat carried by the liquid to the external environment. After being cooled, the liquid returns to the inlet of the water pump 5 through another section of hose 2, forming a closed-loop cooling cycle. This cycle path is reasonably designed, and the coolant has been cooled before entering the water pump 5, which effectively avoids the high-temperature liquid directly acting on the water pump 5, reduces its heat load, and extends the service life of the water pump 5.

[0032] This structure separates the water pump 5 and the water cooling head 4, and allows the coolant to enter the radiator 1 for cooling after flowing through the heat exchange area before entering the water pump 5. This effectively avoids the high-temperature liquid from directly contacting the water pump 5 motor, reduces the heat load of the water pump 5, extends its service life, and improves the stability of system operation.

[0033] The water cooling head 4 is physically separated from the water pump 5, and a cooling radiator 1 is set in the fluid path for priority cooling, which realizes thermal isolation protection for the water pump 5 from the source and avoids the water pump 5 from operating in a high-temperature environment for a long time.

[0034] It should be noted that the structure of the water pump 5 is a mature existing technology, and its working principle and internal structure are known to those skilled in the art. This utility model only utilizes its function and does not improve its internal structure. Therefore, it will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0035] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
