[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely exemplary embodiments of this utility model, and not the only embodiments.

[0026] like Figures 1 to 5 As shown, the heat-dissipating metal access control panel includes a panel body, which includes a front panel 1 and a rear panel 2 that is snapped together with the front panel 1. A display screen 100 and control buttons 101 embedded below the display screen 100 are installed at the middle of the upper part of the surface wall of the front panel 1. The display screen 100 is used to display the basic information of the access control user. The control buttons 101 can be numeric keys or other function keys. An air inlet pipe 3 is installed on the top of the rear panel 2, which is connected to the panel body. A slot 200 is opened at the lower end of the surface wall of the rear panel 2. A heat exhaust pipe 201 connected to the inside of the panel body is installed along the slot 200 to the outside of the rear panel 2. An exhaust fan 4 is installed at the lower end of the inner wall of the rear panel 2 to exhaust the heat inside the panel body.

[0027] The working principle of this embodiment is as follows:

[0028] External air enters the panel body through the air inlet duct 3 and cools down the circuit boards and other components installed inside the panel body. Since there is a certain space inside the panel body, the hot air inside the panel body flows everywhere. After the switch 403 of the exhaust fan 4 is turned on, under the action of external force, the hot air and the heat generated by the operation of the circuit boards and other components enter the heat exhaust duct 201 through the slot 200 and are discharged to the outside of the panel body. This achieves the purpose of using external air to cool down the circuit boards and other components inside the panel body and to discharge the heat generated by the operation inside the panel body.

[0029] Furthermore, the fan blades 400 of the exhaust fan 4 are mounted in the slot 200. This arrangement can quickly exhaust the air and heat inside the panel body through the slot 200. Another advantage of this arrangement is that it saves the space occupied by the fan blades 400 in the rear panel 2. The exhaust fan 4 is fixedly connected to the inner wall of the rear panel 2 by a fixing rod 401. The rear panel 2 is provided with a receiving cavity 402 for housing the motor that drives the exhaust fan 4. One end of the receiving cavity 402 is connected to the fixing rod 401, and the other end of the receiving cavity 402 is connected to a switch 403 located on the surface wall of the rear panel 2 for controlling the start and stop of the exhaust fan 4. Similarly, the above arrangement can save the space occupied by the exhaust fan 4 in the rear panel 2. At the same time, the switch 403 is located on the outside for easy operation by the user, which can improve the user experience.

[0030] Furthermore, in general, the installation of metal access control panels involves fixing the rear panel 2 to an external structure such as a wall or door. Therefore, in order to allow the hot air and heat inside the panel to be discharged smoothly, a certain space is provided when the rear panel 2 is connected to the external structure. For this purpose, in this embodiment, a baffle 5 that can cover the heat exhaust duct 201 is fixedly installed on the outer side of the surface wall of the rear panel 2. Furthermore, in order to provide a buffer between the rear panel 2 and the baffle 5 to protect the rear panel 2, the rear panel 2 and the baffle 5 are fixedly connected by compression springs 6. The compression springs 6 are distributed at the four corners of the surface wall of the rear panel 2. This arrangement can further improve the protection of the rear panel 2.

[0031] Furthermore, to enhance the connection between the baffle 5 and the external structure, suction cups 7 can be provided on the baffle 5 for adsorption and connection with the external structure. The suction cups 7 can be positioned around the perimeter of the baffle 5. This arrangement improves the connection between the baffle 5 and the external structure, thus enhancing stability.

[0032] Furthermore, since some regions experience severe cold waves and high humidity, it is necessary to design a water-absorbing structure for the metal access control panel in this embodiment. To improve the utilization rate of the metal access control panel, the water-absorbing structure is designed inside the air inlet pipe 3 at the top of the rear panel 2. Further, as... Figure 3 and Figure 4 As shown, the inner wall of the air inlet pipe 3 is provided with a support column 300, on which a drying pipe 8 is installed inside the air inlet pipe 3. In order not to affect the entry of external air into the panel body from the air inlet pipe 3, the bottom plate 800 of the drying pipe 8 is provided with multiple air inlet holes 801. A water-absorbing cotton 9 with through holes 900 is placed inside the drying pipe 8. The design purpose of the through holes 900 is the same as that of the air inlet holes 801, which is to ensure that external air can smoothly enter the panel body from the air inlet pipe 3. The water-absorbing cotton 9 can also be replaced by other materials with water absorption effect, such as desiccant. However, it should be noted that the desiccant cannot be a material that releases heat when it comes into contact with water. Otherwise, the heat generated will enter the panel body along the air inlet pipe 3, causing the temperature inside the panel body to rise and affecting the use of components such as circuit boards.

[0033] Furthermore, a cover plate 10 is provided on the top of the air inlet pipe 3. When it is not necessary to dissipate heat inside the panel body, the air inlet pipe 3 can be covered with the cover plate 10 in time to prevent water from entering the panel body.

[0034] The following beneficial effects will be achieved by adopting the above-described embodiments:

[0035] The metal access control panel introduces external air into the panel body through the air inlet duct 3. The external air sweeps and cools the circuit boards and other components inside the panel. Under the action of the exhaust fan 4, the hot air and the heat generated by the circuit boards and other components during operation are discharged, thereby realizing the heat dissipation of the metal access control panel and extending the service life of the circuit boards and other components. The drying tube 8 installed inside the air inlet duct 3 can absorb any moisture that may be present, preventing moisture from entering the panel body and damaging the circuit boards and other components.

[0036] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
