Description

Technical Field

[0001] The utility model belongs to the technical field of chips, and in particular relates to a chip plate structure with high heat dissipation. Background Art

[0002] Chip is a general term for semiconductor component products. It is the carrier of integrated circuits and is divided from wafers. Chip refers to a silicon wafer containing integrated circuits. It is very small and is often a part of a computer or other electronic device. When the current chip is assembled between the circuit board, in order to ensure the stability of the chip installation, a chip holder will be set on the surface of the circuit board, and then the chip will be packaged into the inside of the chip holder.

[0003] The existing chip holder mainly relies on external devices such as heat sinks and fans for heat dissipation. However, since the bottom of the chip fits tightly against the holder, the heat generated at the bottom of the chip is difficult to dissipate effectively, which affects the stability and performance of the chip. In addition, when the chip is plugged into the holder, the pins of the chip need to be carefully combed and positioned. This process is not only complicated to operate, but also once the position of the pin is slightly deviated, it may cause the pin to break, thereby damaging the chip. Utility Model Content

[0004] The purpose of the utility model is to provide a chip board structure with high heat dissipation to solve the problems mentioned in the background technology.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a chip board structure with high heat dissipation, comprising a circuit board body, a fixing seat, a limiting belt, a chip and a positioning plate, wherein a circuit is printed inside the circuit board body, and a fixing seat is fixed to one side of the circuit board body by welding; two limiting belts are fixed to the outer side of the fixing seat, and a chip is movably placed on the upper side of the fixing seat, and the pins of the chip are arranged between the limiting belt and the fixing seat; the front end of the chip is in contact with the positioning plate, and the positioning plate is fixed to the upper end of the fixing seat.

[0007] Furthermore, the fixing seat includes a seat body, a conductive plate and a hook, the seat body is in the shape of a rectangular frame structure, and air guide ports are respectively opened at the front and rear ends of the seat body; a number of the conductive plates are respectively fixed by inlaying on the two side surfaces of the seat body, wherein the number of the conductive plates is the same as the number of the pins of the chip, and the conductive plates are respectively in contact with the corresponding chip pins; the width of the upper end of the conductive plate is greater than the width of the chip pins, and the lower end of the conductive plate is fixed to one side of the circuit board body by welding; the front and rear ends of the seat body are respectively fixed with hooks by welding, and such a setting can improve the heat dissipation effect of the bottom of the chip, and can connect the circuit inside the circuit board body and the pins of the chip.

[0008] Furthermore, the limiting belt includes a rubber plate and an elastic rope, one side of the rubber plate contacts the pins of the chip, and elastic ropes are fixed to both ends of the rubber plate, and the elastic ropes are hung on corresponding hooks respectively. Such an arrangement can separate the pins of the chip from the conductive plate.

[0009] Furthermore, the circuits inside the circuit board body are electrically connected to the corresponding conductive plates, respectively, wherein the conductive plates are electrically connected to the corresponding chip pins, respectively. With this arrangement, electrical signals can be smoothly transmitted between the chip and the circuits inside the circuit board body.

[0010] Furthermore, the positioning plate is in a "7" shape, and the upper end of the positioning plate is buckled into a groove on the side of the chip. Such a configuration can avoid chip installation errors.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model provides two chip installation methods to adapt to different usage scenarios. For short-term use scenarios, the chip can be quickly and easily fixed to the fixing seat through the combination of the positioning plate and the limiting belt. For scenarios that require long-term use, the chip pins can be fixed to the conductive plate by welding to ensure a more stable and lasting connection. This flexible installation method enables the utility model to meet the needs of different users, improves its practicality and adaptability, and does not require detailed combing of the chip pins, reducing the risk of pin breakage. Secondly, the fixing seat is designed with an air guide port, allowing external cold air to enter and pass through the seat body, thereby taking away the heat from the bottom of the chip. This natural convection heat dissipation method can effectively reduce the operating temperature of the chip and prevent performance degradation or damage due to overheating.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner", "all around" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limitations on the present invention.

[0022] See also Figure 1 and Figure 2As shown, the utility model is a chip board structure with high heat dissipation, including a circuit board body 1, a fixing seat 2, a limiting belt 3, a chip 4 and a positioning plate 5. The circuit is printed inside the circuit board body 1, and the fixing seat 2 is fixed to one side of the circuit board body 1 by welding; two limiting belts 3 are fixed to the outer side of the fixing seat 2, and a chip 4 is movably placed on the upper side of the fixing seat 2, and the pins of the chip 4 are arranged between the limiting belt 3 and the fixing seat 2; the front end of the chip 4 is in contact with the positioning plate 5, and the positioning plate 5 is fixed to the upper end of the fixing seat 2.

[0023] like Figure 3 As shown, the fixing seat 2 includes a seat body 21, a conductive plate 22 and a hook 23. The seat body 21 is in the shape of a rectangular frame structure, and air guide ports are respectively provided at the front and rear ends of the seat body 21; a plurality of conductive plates 22 are respectively fixed on the two side surfaces of the seat body 21 by inlaying, wherein the number of the conductive plates 22 is the same as the number of the pins of the chip 4, and the conductive plates 22 are respectively in contact with the corresponding pins of the chip 4; the width of the upper end of the conductive plate 22 is greater than the width of the pins of the chip 4, and the lower end of the conductive plate 22 is fixed to one side of the circuit board body 1 by welding; the front and rear ends of the seat body 21 are respectively fixed with hooks 23 by welding;

[0024] When in use, external cold air will enter through the air duct at one end of the seat body 21, then pass through the seat body 21, and be discharged from the air duct at the other end of the seat body 21. In this process, the cold air will take away the heat at the bottom of the chip 4, thereby achieving effective heat dissipation of the chip 4; at the same time, the conductive plate 22 acts as a bridge connecting the chip 4 with the internal circuit of the circuit board body 1; finally, the setting of the hook 23 facilitates the fixation of the limit belt 3.

[0025] like Figure 4 As shown, the limiting belt 3 includes a rubber plate 31 and an elastic rope 32. One side of the rubber plate 31 contacts the pins of the chip 4, and the two ends of the rubber plate 31 are respectively fixed with elastic ropes 32, and the elastic ropes 32 are respectively hung on the corresponding hooks 23;

[0026] When in use, the rubber plate 21 can squeeze the pins of the chip 4 under the pulling force of the rubber rope 32 to prevent the pins of the chip 4 from being separated from the conductive plate 22 due to vibration or other external factors.

[0027] Specifically, the circuits inside the circuit board body 1 are electrically connected to the corresponding conductive plates 22, wherein the conductive plates 22 are electrically connected to the corresponding pins of the chip 4; when in use, the chip 4 can send electrical signals to the conductive plates 22 through the pins, and then these signals are transmitted to the circuits inside the circuit board body 1 through the conductive plates 22; similarly, the circuit board body 1 can also send signals to the chip 4 or provide the required power through the conductive plates 22.

[0028] Specifically, the positioning plate 5 is in the shape of a "7", and the upper end of the positioning plate 5 is snapped into the groove on the upper side of the chip 4. In order to determine the head and tail of the chip, a groove is opened on the upper side of the head end of the chip. Therefore, only when the chip is correctly placed on the fixing seat 2, the positioning plate 5 can be smoothly snapped into the groove on the upper side of the chip 4. If the chip 4 is placed incorrectly, for example, upside down, the positioning plate 5 will not be able to cooperate with the groove, thereby ensuring the correct installation of the chip 4.

[0029] See also Figure 1-4 As shown, the utility model is a chip board structure with high heat dissipation, and its working principle is: when in use, if the chip 4 is used for a short time, the chip 4 can be placed on the fixing seat 2 according to the position of the positioning plate 5, and the pins of the chip 4 can be clamped and fixed by the limiting belt 3. If it needs to be used for a long time, after the chip 4 is placed on the fixing seat 2, the pins of the chip 4 are soldered to the corresponding conductive plate 22 by tin. At the same time, during use, external cold air will enter at the air guide port at one end of the seat body 21, and then pass through the seat body 21 and be discharged at the air guide port at the other end of the seat body 21. In this process, the cold air will take away the heat at the bottom of the chip 4, thereby realizing effective heat dissipation of the chip 4.
