Abstract
Description
Technical Field
[0001] This utility model relates to the field of projector technology, and in particular to a heat dissipation device and a projector. Background Technology
[0002] Because the projector's light source system requires absolute dust protection, the housing adopts a sealed design, forming a sealed chamber inside. The laser components and lamp parts generate a lot of heat when working, which can easily cause the heat inside the housing to not be dissipated to the outside quickly and effectively. If the heat inside the housing cannot be dissipated quickly and effectively, it will cause the light source system to fail. Utility Model Content
[0003] The main objective of this invention is to provide a heat dissipation device and a projector. The device features a first heat dissipation protrusion with one end extending into the housing and the other end protruding from one side of the housing. This allows heat inside the housing to be dissipated to the outside through the first heat dissipation protrusion. A second heat dissipation protrusion is located on the other side of the housing, allowing heat from the housing's sidewalls to be dissipated to the outside through the second heat dissipation protrusion. Together, the first and second heat dissipation protrusions carry away heat from the housing, ensuring the housing's airtightness while quickly and effectively dissipating heat to the outside, thus improving the housing's heat dissipation effect.
[0004] To achieve the above objectives, the heat dissipation device proposed in this utility model includes:
[0005] case;
[0006] A heat dissipation assembly includes a first heat dissipation protrusion and a second heat dissipation protrusion. One end of the first heat dissipation protrusion extends into the housing, and the other end of the first heat dissipation protrusion protrudes from one side of the housing. The second heat dissipation protrusion is located on the other side of the housing.
[0007] In one embodiment, the first heat dissipation protrusion is provided in a plurality of places, and the plurality of the first heat dissipation protrusions are spaced apart from each other in the housing.
[0008] In one embodiment, a receiving cavity is formed inside the housing, and each of the first heat dissipation protrusions includes a heat absorption section and a heat dissipation section connected to each other. The heat absorption section is disposed inside the receiving cavity, and the heat dissipation section is disposed outside the housing. The heat inside the housing is conducted to the outside of the housing in sequence through the heat absorption section and the heat dissipation section.
[0009] In one embodiment, the length of the heat-absorbing section is shorter than the length of the heat-dissipating section.
[0010] In one embodiment, the first heat dissipation protrusion is a one-piece molded structure.
[0011] In one embodiment, the second heat dissipation protrusion is provided in multiple forms, and the multiple second heat dissipation protrusions are spaced apart on the other side of the housing.

[0016] The technical solution of this utility model adopts a heat dissipation component including a first heat dissipation protrusion and a second heat dissipation protrusion. One end of the first heat dissipation protrusion extends into the housing, and the other end of the first heat dissipation protrusion protrudes from one side of the housing. Thus, the heat inside the housing is dissipated to the outside through the first heat dissipation protrusion, and the heat from the side wall of the housing is dissipated to the outside through the second heat dissipation protrusion. The first and second heat dissipation protrusions work together to remove the heat inside the housing, so as to ensure the airtightness of the housing and quickly and timely dissipate the heat to the outside, thereby improving the heat dissipation effect of the housing.

[0026] This utility model proposes a heat dissipation device, which involves one end of a first heat dissipation protrusion extending into the housing, and the other end of the first heat dissipation protruding from one side of the housing. Heat inside the housing is dissipated to the outside through the first heat dissipation protrusion, and heat from the side wall of the housing is dissipated to the outside through the second heat dissipation protrusion. The first and second heat dissipation protrusions work together to remove heat from the housing, thereby ensuring the housing is airtight while quickly and timely dissipating heat to the outside, thus improving the heat dissipation effect of the housing.
[0027] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the heat dissipation device 100 includes:
[0028] Casing 1;
[0029] The heat dissipation component 2 includes a first heat dissipation protrusion 21 and a second heat dissipation protrusion 22. One end of the first heat dissipation protrusion 21 extends into the housing 1, and the other end of the first heat dissipation protrusion 21 protrudes from one side of the housing 1. The second heat dissipation protrusion 22 is located on the other side of the housing 1.
[0030] In this embodiment, the heat dissipation device 100 includes a housing 1 and a heat dissipation assembly 2. The heat dissipation assembly 2 includes a first heat dissipation protrusion 21 and a second heat dissipation protrusion 22. One end of the first heat dissipation protrusion 21 extends into the housing 1, and the other end of the first heat dissipation protrusion 21 protrudes from one side of the housing 1. Thus, heat inside the housing 1 is transferred to the other end through one end of the first heat dissipation protrusion 21, thereby dissipating heat to the outside. At the same time, the second heat dissipation protrusion 22 is located on the other side of the housing 1, so that heat on the side wall of the housing 1 can be dissipated to the outside through the second heat dissipation protrusion 22. The first heat dissipation protrusion 21 and the second heat dissipation protrusion 22 work together to quickly and timely dissipate heat inside the housing 1 to the outside, thereby improving the heat dissipation effect of the housing 1.
[0031] Meanwhile, in order to ensure the airtightness of the housing 1, the second heat dissipation protrusion 22 and the housing 1 can be integrally formed. Of course, the second heat dissipation protrusion 22 can also be installed on the housing 1 by welding or bonding, or other fixed connection methods, which are not limited here.
[0032] In one embodiment, please refer to Figure 1 and Figure 2 The first heat dissipation protrusion 21 is provided in multiple ways, and the multiple first heat dissipation protrusions 21 are spaced apart on the housing 1. By providing multiple first heat dissipation protrusions 21, the contact area between the first heat dissipation protrusions 21 and the air is increased, thereby improving the heat dissipation effect of the whole machine.
[0033] In one embodiment, a receiving cavity 11 is formed inside the housing 1. Each of the first heat dissipation protrusions 21 includes a heat absorption section 211 and a heat dissipation section 212 connected to each other. The heat absorption section 211 is disposed inside the receiving cavity 11, and the heat dissipation section 212 is disposed outside the housing 1. The heat inside the housing 1 is conducted to the outside of the housing 1 through the heat absorption section 211 and the heat dissipation section 212 in sequence, so as to improve the heat dissipation effect of the housing 1.
[0034] In this embodiment, a receiving cavity 11 is formed inside the housing 1. Each first heat dissipation protrusion 21 includes a heat absorption section 211 and a heat dissipation section 212 connected to each other. The heat absorption section 211 is disposed inside the receiving cavity 11, while the heat dissipation section 212 is disposed on an outer side surface of the housing 1. Thus, the heat in the receiving cavity 11 is transferred to the heat dissipation section 212 after being absorbed by the heat absorption section 211, and then dissipated to the outside. In this way, while ensuring the sealing of the housing 1, the heat can be quickly and timely dissipated to the outside, thereby improving the heat dissipation effect of the housing 1.
[0035] In one embodiment, please refer to Figure 1 and Figure 2 The length of the heat absorption section 211 is shorter than the length of the heat dissipation section 212. This arrangement increases the contact area between the heat dissipation section 212 and the air, thereby facilitating rapid heat dissipation.
[0036] In one embodiment, please refer to Figure 1 and Figure 2 The first heat dissipation protrusion 21 is an integrally molded structure to ensure structural strength and stability, thereby ensuring the sealing of the entire housing 1.
[0037] In one embodiment, please refer to Figure 1 and Figure 2 The second heat dissipation protrusion 22 is provided in multiple ways, and the multiple second heat dissipation protrusions 22 are spaced apart on the other side of the housing 1. By providing multiple second heat dissipation protrusions 22, the contact area between the second heat dissipation protrusions 22 and the air is increased, thereby improving the heat dissipation effect of the whole machine.
[0038] In one embodiment, please refer to Figure 1 and Figure 2 The first heat dissipation protrusion 21 and the second heat dissipation protrusion 22 are both made of metal or ceramic to achieve better heat dissipation. Of course, other materials can also be used, which are not limited here.
[0039] In one embodiment, please refer to Figure 1 and Figure 2 Both the first heat dissipation protrusion 21 and the second heat dissipation protrusion 22 are cylindrical. This arrangement facilitates the dissipation of heat from the first heat dissipation protrusion 21 and the second heat dissipation protrusion 22 to the outside. Of course, the first heat dissipation protrusion 21 and the second heat dissipation protrusion 22 can also be other shapes, which are not limited here.
[0040] In one embodiment, please refer to Figure 1 and Figure 2Both the first heat dissipation protrusion 21 and the second heat dissipation protrusion 22 are solid structures. This arrangement increases the contact area between the first heat dissipation protrusion 21 and the second heat dissipation protrusion 22 and the air, thereby enabling the heat to be dissipated to the outside quickly and timely, thus improving the heat dissipation effect of the casing 1.
[0041] This utility model also proposes a projector, which includes a heat dissipation device 100. The specific structure of the heat dissipation device 100 is as described in the above embodiments. Since this projector adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0042] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
