Description

Technical Field

[0001] This utility model relates to the field of control cabinet technology, and in particular to an elevator control cabinet with high heat dissipation. Background Technology

[0002] The elevator control cabinet is the core control equipment of the elevator system, equivalent to the "brain" of the elevator. It is responsible for coordinating elevator operation, receiving instructions, controlling mechanical components, and ensuring safety. Elevator control cabinets are usually installed in the elevator machine room or at the top of the shaft. In some small elevators, they can be integrated into the top of the car. The main body typically consists of a metal cabinet structure, containing circuit boards, controllers, relays, and other electronic components. Externally, it is equipped with heat dissipation holes, indicator lights, and an operation panel to form a complete elevator control cabinet. More specifically, the core components of the elevator control cabinet include the main controller, frequency converter, power supply module, interface module, and safety protection module. The main controller can use a PLC or dedicated chip to receive signals from buttons, sensors, etc., and then generate operating instructions to control other components and the elevator. The frequency converter adjusts the motor voltage and output power to enable the elevator to perform tasks such as smooth start-stop and precise leveling. The power supply module provides stable power to the elevator and can also provide backup power to handle sudden power outages. The safety protection module integrates safety relays, circuit breakers, etc., to monitor the elevator for overspeed, power outages, and door lock status, and to ensure timely emergency braking.

[0003] Based on the existing structure and control method of the elevator control cabinet, it is prone to generating a large amount of heat during operation. When heat accumulates inside the cabinet, the actual performance of the electronic components will decrease significantly, thus affecting the effectiveness and safety of the control cabinet in controlling the elevator. Existing elevator control cabinet heat dissipation structures typically use air ducts formed between ventilation holes to allow airflow over the electronic components and carry away heat. However, when the airflow velocity is too high or internal dust is not removed in time, the airflow speed can easily affect the operational stability of the electronic components and can also blow dust to the component surfaces, causing surface heat accumulation and significantly impacting the heat dissipation efficiency of the control cabinet. Utility Model Content

[0004] Therefore, it is necessary to provide an elevator control cabinet with high heat dissipation performance to address the technical problem of insufficient heat dissipation performance of existing elevator control cabinets.

[0005] A high heat dissipation elevator control cabinet includes a cabinet body for housing and storing pre-installed electronic components of the elevator control cabinet.

[0006] The cabinet includes a shell, a mounting structure, an air guiding structure, and a connecting structure; the shell is designed to have ventilation structures at both the top and bottom; the mounting structure and the air guiding structure are both located inside the shell; the connecting structure is located at the top of the shell.

[0007] The air guiding structure includes an air inlet, an air guide hood, and an air outlet; the air inlet is located at the bottom of one side wall of the housing; the air outlet is located on the same wall of the housing corresponding to the air inlet; the air inlet and the air outlet are respectively connected to the inner and outer sides of the housing; the air guide hood is correspondingly fastened to the air outlet, and the end of the air guide hood facing the air inlet is set as an open opening.

[0008] A fan is installed on the side of the air guide shroud facing the air outlet, and the output side of the fan is set towards the outside of the casing through the air outlet.

[0009] In one embodiment, the aforementioned air outlet is disposed on the main body portion of the same wall surface as the air inlet; in contrast, the mounting structure is disposed on the top of the housing relative to the air outlet.

[0010] In one embodiment, the above-described mounting structure includes a first mounting portion and a second mounting portion, wherein the first mounting portion is disposed on the adjacent side of the air guide cover; and the second mounting portion is disposed on the top side of the housing relative to the first mounting portion.

[0011] In one embodiment, the first mounting portion described above includes a plurality of first mounting plates, and the plurality of first mounting plates are connected in parallel to each other to one side wall of the housing.

[0012] In one embodiment, each of the first mounting plates described above is configured as a planar plate structure.

[0013] In one embodiment, each of the first mounting plates described above is provided with a plurality of connecting posts.

[0014] In one embodiment, the second mounting part described above includes a plurality of second mounting plates, which are arranged sequentially along a preset direction and mounted on one side wall of the housing.

[0015] In one embodiment, each of the second mounting plates described above is configured as a folding plate mechanism.

[0016] In one embodiment, each of the second mounting plates described above is provided with a plurality of connecting posts.

[0017] In one embodiment, the aforementioned air guide shroud is provided with a third mounting plate, which is located on the side of the air guide shroud facing the air outlet.

[0018] In one embodiment, the air inlet is configured as a first through-hole array, which consists of a plurality of equidistant first through-holes.

[0019] In one embodiment, the air outlet is configured as a second through-hole array, which consists of a plurality of equidistantly arranged second through-holes.

[0020] In one embodiment, the aforementioned high heat dissipation elevator control cabinet also includes a base, which is disposed at the bottom of the housing.

[0021] In one embodiment, the bottom end face of the base corresponding to the housing is configured as a frame structure.

[0022] In one embodiment, the side wall of the base is provided with a plurality of third through holes, each third through hole connecting the inner and outer sides of the base.

[0023] The aforementioned high-heat-dissipation elevator control cabinet introduces airflow through the air inlet, which is then guided to the air outlet by the air guide shroud, forming a cooling airflow with a preset direction and velocity. This airflow carries the heat generated inside the housing to the outside. A fan (not shown) is installed on the side of the air guide shroud facing the air outlet. The output side of the fan faces outward through the air outlet, allowing the fan to provide directional driving force for the airflow inside the housing. This enables the airflow entering the housing through the air inlet to be quickly output through the air outlet, creating a negative pressure zone inside the housing. Hot air generated in the areas with mounting structures inside the housing can flow towards this negative pressure zone and then be output to the outside through the air outlet to dissipate heat. Based on this, the above structure can effectively prevent the airflow entering through the air inlet from directly blowing onto the electronic components, thus avoiding affecting the operational stability of the elevator control cabinet. It can also reduce the adhesion of dust in the airflow to the surface of electronic components, which would cause heat accumulation, thereby greatly improving the heat dissipation performance of the elevator control cabinet.

[0033] Please see Figures 1 to 2This utility model discloses a high heat dissipation elevator control cabinet, which includes a cabinet body 1 for mounting and accommodating pre-set electronic components (not shown). The cabinet body 1 includes a housing 10, a mounting structure 20, an air guide structure 30, and a connecting structure 40. The housing 10 is configured with ventilation structures at both its top and bottom ends, thereby creating a flowing airflow inside and outside the housing 10 to provide basic heat dissipation conditions for the elevator control cabinet. Both the mounting structure 20 and the air guide structure 30 are located inside the housing 10. The mounting structure 20 is used for mounting the electronic components, while the air guide structure 30 guides the airflow inside the housing 10, allowing the cooling airflow to circulate along a pre-set path between the inside and outside of the housing 10, thereby carrying away more heat from inside the housing 10 and enhancing the heat dissipation performance of the elevator control cabinet. The connecting structure 40 is located at the top of the housing 10, allowing the housing 10 to be connected to a pre-set mounting point. Specifically, the air guiding structure 30 includes an air inlet a, an air guide shroud 31, and an air outlet b. The air inlet a is located at the bottom of one side wall of the housing 10. The air outlet b is located on the same wall of the housing 10, corresponding to the air inlet a. The air inlet a and the air outlet b are respectively connected to the inner and outer sides of the housing 10. The air guide shroud 31 is correspondingly fastened to the air outlet b. The end of the air guide shroud 31 facing the air inlet a is set as an open opening. Thus, the airflow entering the housing 10 from the air inlet a can be guided to the air outlet b through the air guide shroud 31, thereby forming a heat dissipation airflow with a preset flow direction and flow rate, which carries the heat generated inside the housing 10 to the outside of the housing 10. More specifically, in one embodiment, a fan (not shown) is provided on the side of the air guide shroud 31 facing the air outlet b. The output side of the fan is provided to the outside of the housing 10 through the air outlet b, so that the fan can provide directional driving force for the airflow inside the housing 10, causing the airflow entering the housing 10 from the air inlet a to be quickly output from the air outlet b, thereby forming a negative pressure zone inside the housing 10. The hot air generated in the area where the mounting structure 20 is provided inside the housing 10 can flow to this negative pressure zone and then be output to the outside of the housing 10 through the air outlet b to achieve heat dissipation. Based on this, the above structure can effectively prevent the airflow input from the air inlet a from blowing directly onto the electronic components and affecting the operational stability of the elevator control cabinet. At the same time, it can also reduce the dust in the airflow from adhering to the surface of the electronic components and causing heat accumulation, thereby greatly improving the heat dissipation performance of the elevator control cabinet.

[0034] Furthermore, the air outlet b is located on the main body of the housing 10 on the same wall as the air inlet a; in contrast, the mounting structure 20 is located on the top of the housing 10 relative to the air outlet b. Thus, based on the guiding effect of the air guide shroud 31, the airflow entering the housing 10 from the air inlet a is preferentially output to the outside of the housing 10 through the air outlet b, thereby reducing the airflow blowing towards the mounting structure 20.

[0035] Furthermore, the mounting structure 20 includes a first mounting portion and a second mounting portion. The first mounting portion is disposed adjacent to the air guide shroud 31; the second mounting portion is disposed on the top side of the housing 10 relative to the first mounting portion. Thus, the first mounting portion and the second mounting portion are respectively used for mounting corresponding electronic components.

[0036] In one embodiment, the first mounting portion specifically includes a plurality of first mounting plates 21. In this embodiment, each first mounting plate 21 is configured as a planar plate structure, and the plurality of first mounting plates 21 are connected parallel to each other to one side wall of the housing 10, thereby forming a plurality of parallel mounting spaces. An airflow channel is formed between adjacent first mounting plates 21, which is conducive to airflow. In this embodiment, each first mounting plate 21 is provided with a plurality of connecting posts 201 for connecting and mounting electronic components.

[0037] In one embodiment, the second mounting section specifically includes a plurality of second mounting plates 22. In this embodiment, each second mounting plate 22 is configured as a folding plate mechanism, and the plurality of second mounting plates 22 are sequentially arranged along a predetermined direction and mounted on one side wall of the housing 10, thereby forming a plurality of mounting spaces raised to a predetermined height relative to the housing 10. The side of each second mounting plate 22 facing the wall of the housing 10 forms an airflow channel, which facilitates airflow. In this embodiment, each second mounting plate 22 is provided with a plurality of connecting posts 201 for connecting and mounting electronic components.

[0038] Furthermore, the air guide shroud 31 is provided with a third mounting plate 32, which is located on the side of the air guide shroud 31 facing the air outlet b, for use in fan installation.

[0039] Furthermore, the air inlet a is configured as a first through-hole array, which consists of several equidistant first through-holes, ensuring the airflow of air inlet a while preventing foreign objects from entering the housing 10.

[0040] Furthermore, the air outlet b is configured as a second through-hole array, which consists of several equidistantly arranged second through-holes. This ensures airflow at the air outlet b while preventing clothing from entering the housing 10.

[0041] Furthermore, the high heat dissipation elevator control cabinet also includes a base 50, which is disposed at the bottom of the housing 10 to provide bottom support for the housing 10 and to provide a stable connection between the housing 10 and the external mounting point. In one embodiment, the bottom side end face of the base 50 is configured as a frame structure, and the side wall of the base 50 is provided with a plurality of third through holes c, each third through hole c connecting the inner and outer sides of the base 50 to further enhance the gas flow inside the base 50 and the housing 10.

[0042] In summary, the high heat dissipation elevator control cabinet disclosed in this utility model introduces airflow through the air inlet, which is then guided to the air outlet by the air guide shroud, thereby forming a heat dissipation airflow with a preset flow direction and velocity, carrying the heat generated inside the housing to the outside. A fan (not shown) is provided on the side of the air guide shroud facing the air outlet, and the output side of the fan is positioned facing outward through the air outlet. This allows the fan to provide directional driving force for the airflow inside the housing, enabling the airflow entering the housing through the air inlet to be quickly output through the air outlet, thus forming a negative pressure zone inside the housing. Hot air generated in the area where the mounting structure is located inside the housing can flow towards this negative pressure zone and then be output to the outside of the housing through the air outlet to achieve heat dissipation. Based on this, the above structure can effectively prevent the airflow entering through the air inlet from directly blowing onto the electronic components, thus avoiding affecting the operational stability of the elevator control cabinet. It can also reduce the adhesion of dust in the airflow to the surface of electronic components, thus reducing heat accumulation and greatly improving the heat dissipation performance of the elevator control cabinet.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
