Description

Technical Field

[0001] The utility model relates to the technical field of computers, in particular to a computer CPU radiator. Background Art

[0002] The computer processor is a functional unit that interprets and executes instructions, also known as the central processing unit or CPU. It is the central nervous system of the computer. When the computer is in use, the CPU runs at high speed and generates a lot of heat. Especially when the external ambient temperature is high, the computer CPU dissipates heat slowly and needs to be assisted by a CPU heat sink. Common CPU heat sinks are generally composed of a base, heat pipes, cooling fins and a cooling fan. The cooling fins and heat pipes are combined into one and installed on the surface of the CPU through the base. The cooling fan is installed on the cooling fins. The heat pipe needs to contact the surface of the CPU to achieve the heat conduction function. In order to prevent dust particles from adhering to the surface of the heat pipe during transportation and affecting the heat dissipation effect, the heat pipe is usually packed in the heat sink during packaging. The surface of the heat pipe in contact with the CPU is pasted with a dust-proof film for dust prevention, but the adhesion between the dust-proof film and the heat pipe is not good. The dust-proof film may still fall off during packaging or transportation, thereby affecting the thermal conductivity of the heat pipe. At the same time, in order to improve the thermal conductivity, thermal grease is applied between the heat pipe and the CPU when the radiator is installed. The amount of thermal grease applied needs to be controlled by the user. If too little thermal grease is applied, the heat dissipation effect cannot be achieved. If too much thermal grease is applied, it will overflow from the CPU surface and even penetrate into the CPU, affecting its service life. Inexperienced users often cannot grasp the amount of thermal grease to apply, resulting in a poor product experience. Therefore, the present application provides a computer CPU radiator to meet the needs. Utility Model Content

The expansion portion with a conical structure facilitates the locking hole 18 to pass over the expansion portion on the top of the locking head 13.

[0038] The symmetrical two side walls of the heat-conducting seat 5 are respectively provided with locking grooves 16, and the two ends of the locking grooves 16 are respectively closed structures. A sliding groove 17 is provided at the bottom of the locking groove 16, and one end of the sliding groove 17 is a closed structure, and the other end of the sliding groove 17 is an open structure. The dust cover 7 is a U-shaped structure, and the symmetrical two sides of the inner wall of the dust cover 7 are respectively fixedly connected with locking strips 21, and the locking strips 21 are adapted to the locking grooves 16 and the sliding grooves 17.

Since the two ends of the locking groove 16 are closed structures, the locking strips 21 are in the locking grooves 16. It cannot move, so when the locking strip 21 is embedded in the locking groove 16, the dust cover 7 and the thermal seat 5 are locked and clamped. Since one end of the sliding groove 17 is an open structure, when the locking strip 21 is embedded in the sliding groove 17, the dust cover 7 and the thermal seat 5 are slidably clamped, and since one end of the sliding groove 17 is a closed structure, the dust cover 7 can only slide toward the open end of the sliding groove 17 to achieve the purpose of separation from the thermal seat 5. A catheter fixing groove 15 is provided on one side wall of the thermal seat 5, and the heat dissipation catheter 4 passes through the catheter fixing groove 15 and is fixedly connected to the thermal seat 5. A hidden groove 14 is provided on the outer side of the catheter fixing groove 15. The hidden groove 14 is a Y-shaped structure, and the top of the hidden groove 14 is connected to the positioning cover tube 9.

[0039] like Figure 6 and Figure 7 As shown, an avoidance groove 27 is provided on the top of the bottom plate of the dust cover 7, and the two ends of the avoidance groove 27 are respectively close to the two groups of locking strips 21. A coating spring piece 20 is provided on the open side of the dust cover 7. The coating spring piece 20 is fixedly connected to the dust cover 7 and is integrally formed. A weak groove 22 is provided on the inner side wall of the coating spring piece 20. By providing the coating spring piece 20, the coating spring piece 20 and the dust cover 7 are smoothly connected in an arc shape, and a weak groove 22 is provided on the inner side wall of the coating spring piece 20. In the natural state, the angle between the coating spring piece 20 and the bottom plate of the dust cover 7 is less than ninety degrees. When a certain external force is applied, the coating spring piece 20 can be moved and deflected and deformed. The weak groove 22 provides a deformation space for the coating spring piece 20. When the locking strip 21 is embedded in the locking groove 16, the dust cover 7 shields the bottom of the thermal seat 5 from dust, and at the same time, the coating spring piece 20 is tightly attached to the outer side wall of the thermal seat 5. For details, please refer to Figure 5 When the locking strip 21 is embedded in the sliding groove 17, there is a gap between the dust cover 7 and the bottom of the heat conducting seat 5, the coating spring 20 has no contact with the side wall of the heat conducting seat 5, and the side is offset inside the dust cover 7. Figure 3 and Figure 6 .

[0040] like Figure 3 , Figure 5 , Figure 8 and Fig. 9As shown, the silicone grease coating mechanism 8 includes a pressurized airbag 23, the pressurized airbag 23 is located inside the positioning cover tube 9 and at the bottom of the pressure plate 11, one end of the pressurized airbag 23 is fixedly connected to an air guide tube 24, the air guide tube 24 is in a Y-shaped structure and is embedded in the recessed groove 14 and connected to the heat-conducting seat 5, the bottom end of the air guide tube 24 is fixedly connected to a sealed capsule cavity 26, a storage bag 25 is fixedly connected between the two groups of sealed capsule cavities 26, and the connection between the pressurized airbag 23 and the air guide tube 24, and the air guide tube 24 and the sealed capsule cavity 26 are fixedly connected. The connection, the connection between the sealing cavity 26 and the storage bag 25, and the side of the storage bag 25 are all provided with a sealing part, which is thermoplastic. When a certain air pressure is used to squeeze the sealing part, the sealing part can be stretched open to make the two ends of the sealing part connected. The silicone grease coating mechanism 8 is made of plastic material as a whole and is an integrated molding structure. By setting the silicone grease coating mechanism 8, the silicone grease coating mechanism 8 made of plastic material can greatly save production costs. A certain amount of thermal conductive silicone grease is loaded into the storage bag 25, and the storage bag The amount of thermal grease in the bag 25 is formulated according to the CPU specifications that the radiator is adapted to, which can maximize the heat dissipation effect of the radiator and avoid the situation where inexperienced installers have difficulty in controlling the amount of grease. When in use, the storage bag 25 is located on the inner side of the coating spring sheet 20. When the locking strip 21 is embedded in the locking groove 16, the coating spring sheet 20 squeezes the air guide tube 24 to cling to the side wall of the thermal seat 5. The storage bag 25 is embedded in the avoidance groove 27 and clings to the side wall of the bottom plate of the thermal seat 5. When the locking strip 21 is embedded in the sliding groove 17, the coating spring piece 20 is buckled and turned toward the inside of the dust cover 7, and scrapes and squeezes the storage bag 25. The user pushes the dust cover 7 to slide relative to the thermal seat 5, so that the locking strip 21 is disengaged from the sliding groove 17. During the sliding process, the coating spring piece 20 pushes the storage bag 25 to squeeze out the thermal grease stored therein and coats it on the bottom of the thermal seat 5. After the dust cover 7 is detached from the thermal seat 5, the thermal seat 5 can be directly installed with the CPU, which saves the step of applying the thermal grease and improves the installation efficiency.

[0041] The working principle provided by the utility model is that before installation, the heat dissipation fin 3 is fixedly connected with the heat dissipation pipe 4, the heat dissipation pipe 4 passes through the pipe fixing groove 15 and is fixedly connected with the thermal conductive seat 5, the locking strip 12 is embedded in the upper locking groove 10, the pressurized air bag 23 is installed inside the positioning cover tube 9 and is located at the bottom of the pressure plate 11. At this time, the pressure plate 11 has no pressure on the pressurized air bag 23, the air guide tube 24 is embedded in the hidden groove 14, the storage bag 25 and the sealed bag cavity 26 are located at the bottom of the thermal conductive seat 5, and when the dust cover 7 is connected to the thermal conductive seat 5, the coating spring piece 20 is arranged on the side of the closed end of the sliding groove 17 of the thermal conductive seat 5, and the locking strip 21 is embedded in the locking groove 16, so that the dust cover 7 is locked and connected with the thermal conductive seat 5, and the bottom of the thermal conductive seat 5 is fully protected to prevent dust particles from adhering during transportation and affecting the heat dissipation effect. At this time, there is no gas in the air guide tube 24 and the sealed bag cavity 26, and the top of the dust cover 7 protrudes from the top of the thermal conductive seat 5.

[0042] During installation, the operator aligns the locking hole 18 with the top of the locking head 13 and presses the fixing fastener 6 so that the locking head 13 passes through the locking hole 18 and is mounted on the fixing fastener 6. During the process of pressing the fixing fastener 6, the locking head 13 moves downward, and the locking bar 12 disengages from the upper locking groove 10 and enters the lower locking groove 10. The operator relies on the vibration generated by the locking bar 12 entering the locking groove 10 to confirm the action of stopping pressing the fixing fastener 6. The pressure plate 11 moves downward to reduce the gap between the top of the locking head 13 and the top of the positioning cover tube 9. At this time, the fixing fastener 6 is clamped and fixed between the expansion part at the top of the locking head 13 and the top wall of the positioning cover tube 9.

[0043] As the pressure plate 11 moves downward, it squeezes the pressurized airbag 23. The air pressure inside the pressurized airbag 23 expands the sealing portion between the pressurized airbag 23 and the air duct 24. The gas in the pressurized airbag 23 enters the air duct 24. The air duct 24 is inflated and expanded by the gas, and the sealing portion between the air duct 24 and the sealed bag cavity 26 is expanded. The gas enters the sealed bag cavity 26 to expand the sealing portion between the sealed bag cavity 26 and the storage bag 25, thereby squeezing the thermal grease in the storage bag 25 and expanding the sealing portion on the side of the storage bag 25, so that the thermal grease can be squeezed out.

[0044] When the fixing fastener 6 is pressed, the dust cover 7 is pressed downward, so that the locking strip 21 is disengaged from the locking groove 16 and enters the sliding groove 17. The coating spring piece 20 lacks the restriction of the thermal seat 5 and is offset and deformed toward the inside of the dust cover 7. The operator pushes the dust cover 7 to disengage and slide from the thermal seat 5, and during the sliding process, the coating spring piece 20 is driven to scrape and squeeze the storage bag 25, squeezing out the thermal grease therein and coating it on the bottom of the thermal seat 5. After the dust cover 7 is disengaged from the thermal seat 5, the thermal seat 5 is pressed against the surface of the CPU, and the fixing fastener 6 is fixed to the base with bolts.

[0045] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0046] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
