Description

Technical Field

[0001] The utility model relates to the technical field of backpacks, and particularly relates to a backpack with a heat dissipation function. Background Technique

[0002] The working principle of a laser is mainly based on the principles of stimulated emission and optical resonance. In a laser, a pump source provides energy to excite the electrons of atoms or ions in the laser medium, causing them to be in an excited state. When the excited atoms or ions transition to the ground state, a beam of light with the same frequency as the light of the pump source and good coherence, that is, a laser beam, will be emitted. Two highly reflective optical mirrors are installed in the optical resonator, one of which is a semi-transparent mirror and the other is a total reflection mirror. Through multiple reflections in the optical resonator, the intensity of the laser is enhanced, and a laser output optical path is formed, becoming a laser beam.

[0003] Currently, lasers have good applications in various fields. For example, laser beams generated by lasers are used to clean debris on high-voltage wires, perform some laser cleaning, laser snow removal, etc. When performing these tasks, mostly portable laser devices are used. By placing the laser in a backpack or making the entire laser device in the form of a backpack, it is convenient for operators to carry the laser to the place where it is needed for use.

[0004] For example, the patent application No. CN202320381701.9 discloses a backpack-type long-distance laser obstacle removal device, including: a backpack, a zoom laser emitter, a ranging unit, an infrared sight, a laser, a power supply, and a controller. The laser and the power supply are both placed in the backpack. The light output port of the laser is connected to the light input port of the zoom laser emitter through an optical fiber; the ranging unit and the infrared sight are respectively installed on the zoom laser emitter, and a video unit is equipped on the infrared sight. The laser, the ranging unit, and the zoom laser emitter are respectively electrically connected to the controller. The beneficial effects of the utility model are: a backpack is introduced, and the laser and the power supply are both placed in the backpack, with strong portability, can operate without being restricted by the region, has strong applicability, uses the laser to remove the target object, has higher removal efficiency and reliability, uses the laser as an energy carrier, has the characteristics of concentrated energy and high precision, does not require high operation skills for operators, is easy to operate, has low personnel use cost, and high safety.

[0005] As shown in the above utility model, placing a laser, a power supply, etc. in a backpack for use can greatly improve the convenience of use and portability. However, since a large amount of heat is generated during the use of the laser, the power supply, etc., especially after long-term use, the temperature will rise rapidly. Since the backpack is a closed space, the heat is difficult to dissipate, and the laser and the power supply are prone to failure under high temperature conditions. In order to improve the heat dissipation performance of the backpack, as shown in the above utility model, in the prior art, the backpack for carrying the laser is provided with some heat dissipation holes for heat dissipation, but such a method can only dissipate heat by means of passive air flow, and the heat dissipation effect on the laser is not good, and it is difficult to meet the heat dissipation effect required for the long-term use of the laser.

Detailed implementation manners

[0027] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0028] Figures 1 to 7 The figure shows an embodiment of the present utility model.

[0029] Embodiment:

[0030] A backpack with a heat dissipation function includes a backpack body 1. A placement cavity 2 is arranged inside the backpack body 1. Heat dissipation holes 3 communicating with the placement cavity 2 are arranged on the side of the backpack body 1. A upper placement board 4 is horizontally arranged at a position near the top inside the placement cavity 2. Upper mounting holes 5 penetrating through the upper and lower sides are arranged on the upper placement board 4. An upper heat dissipation fan 6 is installed in the upper mounting holes 5. A lower placement board 7 is horizontally arranged at a position near the bottom of the placement cavity 2. Lower mounting holes 8 penetrating through the upper and lower sides are arranged on the lower placement board 7. A lower heat dissipation fan 9 is installed in the lower mounting holes 8. By arranging the lower placement board 7, it is convenient to place a laser, a power supply, etc. into the placement cavity 2 and keep a distance from the bottom of the placement cavity 2, so as to drive the air flow in the placement cavity 2 by means of the upper heat dissipation fan 6 and the lower heat dissipation fan 9 to form convection. And the convective air will be discharged through the heat dissipation holes 3 on the side after collision. During the process of air discharge, the heat in the placement cavity 2 will be taken away and discharged through the heat dissipation holes 3. By accelerating the air flow, sufficient heat exchange is carried out by means of air, so as to reduce the temperature of the laser, the power supply, etc., and facilitate the long-term use of the laser. By arranging the upper placement board 4, other tools, parts, etc. can be placed on the upper side of the upper placement board 4. The present utility model adopts upper and lower convective blowing for heat dissipation. Compared with unidirectional diversion heat dissipation, it can blow and dissipate heat on both the upper and lower sides of the laser, the power supply, etc. simultaneously, improving the heat dissipation efficiency. And by virtue of the relatively large area on the side, enough heat dissipation holes 3 can be arranged to discharge hot air.

[0038] Threading notches 25 are recessed at the edges of the upper placement plate 4; threading holes 26 communicating with the placement cavity 2 are provided on the side of the backpack body 1.
