Description

Technical Field

[0001] This utility model relates to the field of lamp heat sink technology, specifically to a lamp heat sink structure with high efficiency heat dissipation. Background Technology

[0002] In lighting fixtures, the heat sink is mainly used to dissipate heat from the lamp panel. Since the temperature of the lighting fixture is high when it is working, if the heat is not dissipated in time, the temperature of the lighting fixture will be too high and damage the circuit. Therefore, the heat dissipation performance of the heat sink is particularly important and directly affects the normal operation and service life of the lighting fixture.

[0003] Currently, most lamp heat sinks on the market are fixedly connected to the outer casing by a ring plate. Heat is dissipated between the heat sink and the outer casing through the surface area of ​​the ring plate. Due to the small contact area, the heat dissipation is poor and the heat sink has low heat dissipation efficiency. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a high-efficiency heat dissipation structure for lamps, comprising:

[0005] The outer casing has a cap-shaped structure, and the interior of the outer casing is used to install the lamp panel;

[0006] The heat dissipation fin assembly has several groups of heat dissipation fins arranged in an array along the center of the outer shell on the outside of the outer shell. Adjacent heat dissipation fin assemblies are connected to each other, and the heat dissipation fin assemblies are detachably connected to the outside of the outer shell and are in close contact with and fixed to the outside of the outer shell.

[0007] A further embodiment of this utility model is that the outer shell includes an upper end face, a lower end face, and an outer side face, the outer side face being connected between the upper end face and the lower end face, and the upper end face, the lower end face, and the outer side face all being in close contact with the heat dissipation fin assembly.

[0008] A further embodiment of this utility model is that the heat dissipation fin assembly includes a first heat dissipation fin and a second heat dissipation fin, and the first heat dissipation fin and the second heat dissipation fin are connected by a snap-fit ​​at a certain angle.

[0009] A further embodiment of this utility model is that each of the first and second heat dissipation fins has an insertion part on one side. A sword-shaped protrusion is formed on one side of the insertion part, and a positioning hook is formed on the upper and lower sides of the sword-shaped protrusion on the insertion part. A positioning ear corresponding to the sword-shaped protrusion is also provided on the outer side of the insertion part, and a positioning buckle corresponding to the positioning hook is provided on the upper and lower sides of the positioning ear. When the first heat dissipation fin and the second heat dissipation fin are connected, the sword-shaped protrusion passes through the positioning ear for positioning and engagement, and the positioning hook and the positioning buckle are engaged.

[0010] A further embodiment of this utility model is that the bottom of the first heat dissipation fin and the second heat dissipation fin are bent to form a first bent piece, the first heat dissipation fin is also bent to form a second bent piece, and the second heat dissipation fin is bent to form a third bent piece. When the first heat dissipation fin and the second heat dissipation fin are assembled, the first bent pieces on the first heat dissipation fin and the second heat dissipation fin are located on the same horizontal plane and are adapted to each other and in close contact. The second bent piece and the third bent piece are located on the same horizontal plane and are adapted to each other and in close contact.

[0011] A further embodiment of this utility model is that the upper ends of the first heat dissipation fin and the second heat dissipation fin are provided with a fourth bent piece, and the fourth bent pieces are located on the same horizontal plane and are adapted to each other and in close contact.

[0012] A further embodiment of this utility model is that protrusions are provided on the upper and lower surfaces of the outer shell, and positioning holes are provided on the first, second, and third bent pieces. When the heat dissipation fin assembly is installed on the outer shell, the positioning holes are inserted and positioned with the protrusions, so that the first bent piece is in close contact with the lower surface of the outer shell, and the second and third bent pieces are in close contact with the upper surface of the outer shell.

[0013] A further embodiment of this utility model is that the inner sides of the first heat dissipation fin and the second heat dissipation fin are both bent to form a fifth bent piece, and the fifth bent piece is in close contact with the outer side of the outer shell.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This heat dissipation structure consists of two main parts: the outer shell and the heat dissipation fin assembly. The heat dissipation fin assembly is directly and tightly connected to the outer shell, unlike the indirect connection through a ring plate as in traditional methods. Therefore, the heat dissipation fin assembly contacts the outer shell on multiple surfaces, thereby increasing the contact area and improving heat dissipation performance and working efficiency.

[0027] This embodiment provides a high-efficiency heat dissipation structure for a lamp, including:

[0028] The outer shell 2 has a cap-shaped structure. The light panel is installed inside the outer shell 2. The outer shell 2 includes an upper end face 20, a lower end face 21 and an outer side face 22. The outer side face 22 is connected between the upper end face 20 and the lower end face 21. The upper end face 20 and the lower end face 21 of the outer shell 2 are provided with protruding posts K.

[0029] It also includes a heat dissipation fin assembly 1, which has several groups.

[0030] Furthermore, several sets of heat dissipation fins are arranged in an array along the center of the outer shell 2 on the outside of the outer shell 2. Adjacent heat dissipation fin assemblies 1 are interconnected. The heat dissipation fin assembly 1 is directly and tightly contacted and fixed to the outside of the outer shell 2. Specifically, the upper end surface 20, the lower end surface 21, and the outer surface 22 are all tightly contacted and fixed to the heat dissipation fin assembly 1. By having multiple surfaces of the heat dissipation fin assembly 1 contact the outer shell 2, the contact area with the outer shell 2 can be increased, thereby improving the heat dissipation effect.

[0031] In this utility model, the heat dissipation fin assembly 1 further includes a first heat dissipation fin 10 and a second heat dissipation fin 11. The first heat dissipation fin 10 and the second heat dissipation fin 11 are connected by a certain angle. The assembled heat dissipation fin assembly 1 is then assembled and connected to form a ring structure and then assembled onto the outer shell 2.

[0032] Furthermore, in this invention, each of the first heat dissipation fin 10 and the second heat dissipation fin 11 has a plug-in portion A on one side. A sword-shaped protrusion B is formed on one side of the plug-in portion A. Positioning hooks C are formed on the upper and lower sides of the sword-shaped protrusion B. A positioning ear D corresponding to the sword-shaped protrusion B is also provided on the outer side of the plug-in portion A. Positioning buckles E corresponding to the positioning hooks C are provided on the upper and lower sides of the positioning ear D. When the first heat dissipation fin 10 and the second heat dissipation fin 11 are connected, the sword-shaped protrusion B passes through the positioning ear D for positioning and engagement, and the positioning hooks C and positioning buckles E are engaged, thereby achieving a tight connection between the first heat dissipation fin 10 and the second heat dissipation fin 11.

[0033] Furthermore, in this invention, the bottom of the first heat dissipation fin 10 and the second heat dissipation fin 11 are bent to form a first bent piece F, the first heat dissipation fin 10 is also bent to form a second bent piece G, and the second heat dissipation fin 11 is bent to form a third bent piece H. When the first heat dissipation fin 10 and the second heat dissipation fin 11 are assembled, the first bent pieces F on the first heat dissipation fin 10 and the second heat dissipation fin 11 are located on the same horizontal plane and are adapted to each other and in close contact. The second bent piece G and the third bent piece H are located on the same horizontal plane and are adapted to each other and in close contact, thereby improving the stability of the connection between the first heat dissipation fin 10 and the second heat dissipation fin 11.

[0034] Furthermore, in this invention, the upper ends of the first heat dissipation fin 10 and the second heat dissipation fin 11 are also provided with a fourth bent piece I, and the fourth bent pieces I are located on the same horizontal plane and are adapted to each other and in close contact.

[0035] Furthermore, in this invention, the first bent piece F, the second bent piece G, and the third bent piece H are all provided with positioning holes J. When the heat dissipation fin assembly 1 is installed on the outer shell 2, the positioning holes J are inserted and positioned with the protrusions K. The positioning holes J and the protrusions K enable the heat dissipation fin assembly 1 to be tightly installed on the outer shell 2. The first bent piece F is in close contact with the lower end face 21 of the outer shell 2, and the second bent piece G and the third bent piece H are in close contact with the upper end face 20 of the outer shell 2.

[0036] Furthermore, in this invention, the inner sides of the first heat dissipation fin 10 and the second heat dissipation fin 11 are both bent to form a fifth bent piece L. The fifth bent piece L is in close contact with the outer side surface 22 of the outer shell 2. Therefore, the first bent piece F is bonded to the lower end surface 21 of the outer shell 2 for heat conduction, the second bent piece G and the third bent piece H are bonded to the upper end surface 20 of the outer shell 2 for heat conduction, and the fifth bent piece L is bonded to the outer side surface 22 of the outer shell 2 for heat conduction. The bending structure generates a surface shape to increase the contact area with the outer shell 2, thereby improving the heat dissipation performance.
