Description

Technical field

[0001] The present invention relates to a water cooling radiator, in particular a water cooling radiator with a built-in water pump. State of the art

[0002] A water-cooled radiator is configured to dissipate heat using a coolant circulated by a pump. Compared to air cooling, water-cooled radiators offer the advantages of quiet operation, stable cooling, and reduced environmental impact. The heat dissipation capacity of a water-cooled radiator is proportional to the flow rate of the coolant (water or another liquid). This flow rate is directly related to the pump's power output. Furthermore, water has a high heat capacity, giving the water-cooled system excellent heat dissipation capabilities.

[0003] A prior art water cooling radiator assembly typically consists of a water cooling radiator, a water cooling block, and a water line. The water line connects the water cooling radiator to the water cooling block. The water line allows water to circulate within the water cooling radiator and the water cooling block. After absorbing heat from the water cooling block, the water flows to the water cooling radiator to dissipate the heat, and then returns to the water cooling block. According to the prior art, the water cooling radiator of the assembly includes a water reservoir. This reservoir does not function as a water pump, resulting in slow water flow within the water cooling radiator and low heat dissipation efficiency.Furthermore, there is no partition in the water reservoir, which shortens the distance the water flows through the water cooling radiator, preventing effective cooling and heat dissipation. Therefore, the water cooling radiator requires a modification to meet current technical standards.

[0004] For the prior art, reference is made to publication US 2009 / 0 044 929 A1, which discloses a liquid cooling module comprising a sealed unit, a heat dissipation module, an outlet pipe and an inlet pipe, wherein the heat dissipation module includes a water cooling radiator according to the preamble of one of claims 1 or 2.

[0005] Furthermore, another conventional liquid cooling heat dissipation arrangement is known from document US 2006 / 0 185 378 A1, which comprises a cooling plate module, a liquid cooling module and a liquid drive module. Object of the invention

[0006] In view of the disadvantages of the prior art embodiment, the main objective of the present invention is to create a water cooling radiator with a built-in water pump, which effectively solves the problem of the insufficient heat dissipation of the prior art water cooling radiator and the inability to effectively cool and dissipate heat for water.

[0007] To achieve the above-mentioned objectives, the following technical solutions are used in the present invention: According to one aspect of the present invention, a water-cooling radiator according to claim 1 is provided, comprising a first water collection container, a second water collection container, and several cooling tubes. The cooling tubes are formed with cooling fins. Two ends of the cooling tubes are connected to the first water collection container and to the second water collection container, respectively. The first water collection container consists of a box housing, a box cover, and a water pump cover. The box housing is made of heat-dissipating metal. A water pump chamber is formed within the box housing. A partition is provided in the box housing. The partition divides the interior of the box housing into a water inlet chamber and a water outlet chamber, which are separate from each other. The water outlet chamber is connected to the water pump chamber. The box housing has a water inlet and a water outlet. The water inlet is connected to the water inlet chamber.The water outlet is connected to the water pump chamber. A sealed water pipe connection is installed at each water inlet and outlet. The box cover is attached to the box housing and configured to seal the openings of the water inlet and outlet chambers. The box cover has multiple mounting slots. The ends of some cooling pipes are hermetically sealed in certain mounting slots and connected to the water inlet chamber. The ends of other cooling pipes are hermetically sealed in other mounting slots and connected to the water outlet chamber. The water pump cover is attached to the box housing and configured to seal an opening of the water pump chamber. A water pump is mounted on the inside of the water pump cover. An impeller is attached to an output shaft of the water pump. The impeller is installed in the water pump chamber and is driven to rotate by the water pump.

[0008] According to a further aspect of the present invention, a water-cooling radiator according to claim 2 is provided, comprising a first water collection container, a second water collection container, and several cooling tubes. Two ends of the cooling tubes are connected to the first water collection container and to the second water collection container, respectively.

[0009] The cooling pipes are formed with cooling fins. The first water collection tank consists of a box housing, a box cover, and a water pump cover. The box housing is made of heat-dissipating material. A partition is provided within the box housing. This partition divides the interior of the box housing into a separate water inlet chamber and a water outlet chamber. The box housing has a water inlet and a water outlet. The water inlet is connected to the water inlet chamber. A sealed water pipe connection is installed at each water inlet and outlet. The box housing has several mounting slots. The ends of some cooling pipes are hermetically sealed in certain mounting slots and connected to the water inlet chamber. The ends of other cooling pipes are hermetically sealed in other mounting slots and connected to the water outlet chamber.The box cover is attached to the box housing and is configured to seal the openings of the water inlet chamber and the water outlet chamber. The box cover incorporates a water pump chamber. The water outlet chamber is connected to the water pump chamber. The water outlet is connected to the water pump chamber. The water pump cover is attached to the box cover and is configured to seal an opening of the water pump chamber. A water pump is attached to the inside of the water pump cover. An impeller is attached to an output shaft of the water pump. The impeller is installed in the water pump chamber and is driven to rotate by the water pump.

[0010] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, the following is evident from the technical solutions mentioned above: The water pump chamber is formed as a single unit within the housing or housing cover and, together with the water pump, impeller, and pump cover, forms a water pump structure with excellent airtightness, effectively combining the water pump and the primary water reservoir. This significantly increases the water flow velocity within the water-cooling radiator, improving heat dissipation efficiency. Furthermore, a baffle within the housing directs hot water away from the water inlet, greatly increasing the water flow within the radiator. This allows the water to be cooled effectively for heat dissipation, thereby significantly enhancing the overall heat dissipation performance of the product.
