Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation, in particular to a heat spreader with an elastic structure. Background Art

[0002] With the rapid development of electronic devices, heat dissipation has become one of the key factors restricting their performance improvement. As an efficient heat dissipation component, vapor chambers are widely used in the field of heat dissipation of electronic devices. However, the traditional connection method between vapor chambers and heat dissipation components often has problems such as unstable connection and poor heat dissipation effect.

[0003] After searching, the Chinese patent document application number: 202220262271.4 discloses a new type of elastic heat spreader, including a heat spreader body, the top of the heat spreader body is provided with a groove, and the inside of the groove is provided with a protrusion, the top of the protrusion is fixed with an elastic structure, the elastic structure includes a spring, the spring is arranged at the top of the heat spreader body, the top and bottom of the spring are provided with a guide column, and the top of the guide column is fixed with a connecting piece, and the bottom of the heat spreader body and the bottom of the elastic shell are provided with a protective structure. The utility model is provided with an elastic structure, and after a certain pressure is applied, the heat spreader is elastically deformed and compressed in the thickness direction, and after the pressure is released, the heat spreader restores its original thickness, and the spring is evenly provided at the top of the heat spreader body, and the elastic deformation is generated by the torque at the break, that is, the elastic force of the spring realizes the rebound of compression, thereby improving the tightness of the connection between the heat spreader and the rigid heat dissipation structure.

[0004] However, the elastic heat spreader of the above-mentioned novel structure still has the following defects:

[0005] The above-mentioned elastic heat spreader of the new structure is provided with an elastic structure. After a certain pressure is applied, the heat spreader undergoes elastic deformation and compression in the thickness direction. After the pressure is released, the heat spreader restores its original thickness. Springs are evenly arranged on the top of the heat spreader body, and elastic deformation is generated by relying on the torque at the step difference, that is, the elastic force of the spring realizes the compressed rebound, thereby improving the tightness of the connection between the heat spreader and the rigid heat dissipation structure. However, the heat spreader only tightly connects the rigid heat dissipation structure through the action of the spring. After long-term use, the spring may deform and cause the connection to loosen, thereby causing the contact area between the heat spreader and the heat dissipation structure to become smaller, affecting the heat dissipation effect. Therefore, we need a heat spreader with an elastic structure to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a heat spreader with an elastic structure, which can resist the deformation of the elastic component to a certain extent and maintain the stability of the connection mainly through the supporting effect of the sleeve. Even if a certain deformation occurs during use, the elastic component can automatically adjust to ensure close contact between the heat dissipation structure and the heat spreader body. The shock-absorbing pad can effectively absorb and disperse external vibrations to prevent damage to the internal structure, and the elastic filling layer can fill the tiny gaps caused by manufacturing errors or improper installation to ensure smooth heat transfer. The provision of the thermal conductive layer enables heat to be transferred from the heat spreader body to the heat dissipation structure more quickly, thereby improving the overall heat dissipation efficiency.

[0021] 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 in 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.

[0022] See also Figure 1-4The utility model provides a technical solution: a heat spreader with an elastic structure, comprising a heat spreader body 6, a plurality of equidistant grooves are provided on the top surface of the heat spreader body 6, a sleeve 10 is installed inside the groove, an elastic component is installed inside the sleeve 10, a shockproof pad 5 is bonded and connected to the surface of the heat spreader body 6, an elastic filling layer 4 is provided on the shockproof pad 5, a heat conductive layer 3 is provided on the surface of the elastic filling layer 4, a heat dissipation structure 1 is bonded and connected above the heat conductive layer 3, through holes 8 are provided on the surfaces of the shockproof pad 5, the elastic filling layer 4 and the heat conductive layer 3, the side walls of the sleeve 10 pass through the through holes 8 and are arranged below the heat dissipation structure 1, a support sheet 13 is provided above the elastic component, and the top of the support sheet 13 is bonded and connected to the bottom of the heat dissipation structure 1;

[0023] During use, the supporting effect of the sleeve can resist the deformation of the elastic component to a certain extent and maintain the stability of the connection. Even if a certain deformation occurs during use, the elastic component can automatically adjust to ensure close contact between the heat dissipation structure 1 and the heat spreader body 6. The shock-absorbing pad 5 can effectively absorb and disperse external vibrations to prevent damage to the internal structure, while the elastic filling layer 4 can fill the tiny gaps caused by manufacturing errors or improper installation to ensure smooth heat transfer. The setting of the thermal conductive layer 3 enables heat to be transferred from the heat spreader body 6 to the heat dissipation structure 1 more quickly, thereby improving the overall heat dissipation efficiency.

[0024] The elastic component includes a spring 12, a protrusion 11 is provided at the lower end of the spring 12, the bottom end of the protrusion 11 is fixedly mounted on the inner bottom end of the sleeve 10, and the top end of the spring 12 is fixedly connected to the bottom end of the support plate 13. Due to the close connection between the spring 12 and the support plate 13, the thermal resistance between them is minimized, and heat can be more efficiently transferred to the heat dissipation structure 1 through the support plate 13, which helps to ensure smooth heat transfer between the heat spreader body 6 and the heat dissipation structure 1, thereby improving the overall heat dissipation efficiency.

[0025] External threads are provided on the outer walls around the protrusion 11, and the bottom end of the spring 12 is threadedly installed on the protrusion 11. The threaded connection is not only stable, but also the installation and disassembly process is relatively simple. The staff can easily complete the installation or disassembly operation by rotating the spring 12 or the protrusion 11, which greatly improves the work efficiency and reduces the difficulty of installation and maintenance.

[0026] A plurality of wave grooves are provided on the surface of the heat-conducting layer 3, and the plurality of wave grooves are equidistantly installed on the surface and bottom surface of the heat-conducting layer 3. The shape of the wave grooves helps to form heat convection, promote the transfer and dissipation of heat, and when air or heat dissipation medium flows between the wave grooves, it can more efficiently take away the heat, reduce local high temperature, and make the heat distribution more uniform.

[0027] A fixing layer 7 is welded to the bottom end of the heat spreader body 6, and the fixing layer 7 is configured as a reinforcing rib layer. The reinforcing rib layer, as a reinforcing structure, can significantly improve the overall strength and rigidity of the heat spreader body 6, and help prevent deformation or damage caused by external force or temperature changes during use, thereby ensuring that the heat spreader body 6 can work stably for a long time.

[0028] Bolts 2 are threadedly installed around the surface of the heat dissipation structure 1, and threaded holes 9 are opened on the surfaces of the thermal conductive layer 3, the elastic filling layer 4 and the shock-absorbing pad 5. One end of the bolt 2 is threaded through the thermal conductive layer 3 and the elastic filling layer 4 and is threadedly installed on the shock-absorbing pad 5. Through the cooperation of the bolt 2 and the threaded hole 9, the heat dissipation structure 1 can be firmly connected to the thermal conductive layer 3, the elastic filling layer 4 and the shock-absorbing pad 5. This connection method is not only firm and reliable, but also can ensure that the heat dissipation structure 1 will not loosen or shift during use, thereby maintaining a stable heat dissipation effect.

[0029] The surface of the elastic filling layer 4 is bonded to the bottom end of the heat-conducting layer 3, and the bottom end of the elastic filling layer 4 is fitted and connected to the surface of the shock-absorbing pad 5. Since the elastic filling layer 4 has a certain elasticity, it can provide a certain buffer during thermal expansion, reduce the thermal stress concentration caused by temperature changes, and help protect the heat dissipation structure 1 and the heat spreader body 6. The combined use of the elastic filling layer 4 and the shock-absorbing pad 5 further enhances the overall shock-absorbing performance.
