[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] See also Figure 1 and 2 The present invention provides an infrared module heat dissipation structure, including:

[0027] The front shell 1 and the rear shell 5 are spliced together to form a shell with an installation space, and a boss is provided inside the rear shell 5;

[0028] The middle bracket 4 is placed on the boss and fixed;

[0029] The infrared core 2 is provided on the middle bracket 4;

[0030] The heat-conducting member 3 is provided between the middle bracket 4 and the housing, and is in close contact with the middle bracket 4 and the housing, and is used to conduct the heat generated by the infrared core 2 from the side of the housing to the outer shell for heat dissipation.

[0031] Specifically, the assembly steps of the infrared module are as follows: 1. Install the infrared core 2 on the middle bracket 4 in advance, and attach the heat-conducting member 3 to the side;

[0032] 2. Place the middle bracket 4 assembly on the rear shell 5, and apply side pressure to ensure that the heat-conducting member 3 and the middle bracket 4 & the rear shell 5 are in uniform contact, and then screw-fasten the middle bracket 4 and the rear shell 5;

[0033] 3. When the front shell 1 is assembled downward in alignment, the heat-conducting member 3 is pressed to be in uniform contact with the front shell 1 & the middle bracket 4, and then the front and rear shells are screw-fastened.

[0034] In this embodiment, by placing the heat-conducting member 3 on the side of the infrared core 2 and being in close contact with the middle bracket 4 and the housing, the heat generated by the infrared core 2 can be conducted from the side of the housing to the outer shell for heat dissipation, solving the problem that the space in the internal vertical direction of some infrared modules is limited, ensuring the effective heat dissipation of the infrared core 2, and improving the service life of the infrared core.

[0035] In one embodiment, the heat-conducting member 3 is made of a heat-conducting silicone sheet or heat-conducting silicone grease. The heat-conducting silicone grease is an industrially synthesized soft sheet-like heat-dissipating material.

[0036] In one embodiment, a heat-conducting layer is coated on the outer surface around the infrared core 2. With this setting in this embodiment, it avoids the hard contact between metals. Visually, it fits well, but actually at the molecular level, it is partially in contact to enhance heat dissipation.

[0037] In one embodiment, the heat-conducting layer is made of a heat-conducting paste. The heat-conducting paste is a liquid with low fluidity and is not easily volatile heat-dissipating material.

[0038] In one embodiment, please refer to Figure 3 , a guide groove 6 is provided at the contact part of the middle bracket 4, the housing and the heat-conducting member 3. With this setting in this embodiment, it can increase the contact area between the heat-conducting member 3 and the middle bracket 4 and the housing, and improve the heat-conducting and heat-dissipating effects.

[0039] Specifically, the guide groove 6 is a straight groove or a corrugated groove arranged uniformly.

[0040] Specifically, both ends of the guide groove 6 are sealed. With this setting in this embodiment, it can avoid the problem that when the middle bracket 4 and the housing squeeze the heat-conducting member 3, the heat-conducting member 3 spreads to a position where it cannot play a heat-dissipating effect.

[0041] In one embodiment, heat dissipation holes are provided on the housing near the contact part with the heat conducting member 3. With this arrangement in this embodiment, the heat dissipation effect can be further improved.

[0042] In one embodiment, a heat conducting rod 7 is provided on one side of the intermediate bracket 4 away from the contact end with the outer shell, and the end of the heat conducting rod 7 abuts against the inner wall of the outer shell. With this arrangement in this embodiment, the heat that has not been conducted to the heat conducting member 3 can be conducted to the outer shell through the heat conducting rod 7, further improving the heat dissipation effect.

[0043] In one embodiment, at least two heat conducting rods 7 are provided and are arranged in a staggered manner on the intermediate bracket 4.

[0044] It should be noted that if there are directional indications such as up, down, left, right, front, back... in the embodiments of the present utility model, then the directional indications are only used to explain the relative position relationship, movement conditions, etc. between components in a certain specific posture as shown in the drawings. If the specific posture changes, then the directional indications will also change accordingly.

[0045] In addition, if there are descriptions such as "first", "second", etc. in the embodiments of the present utility model, then the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or the solution where A and B are satisfied simultaneously. In addition, "a plurality" means more than two. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist.
