Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for relay protection, specifically to an intelligent heat dissipation housing for a relay protection device. Background Technology

[0002] A relay protection device is an automatic device that detects faults or abnormal operating conditions of electrical components in a power system and triggers circuit breakers to trip or send signals. Its main function is to quickly and accurately disconnect faulty components from the system when a fault occurs, ensuring the continued normal operation of fault-free parts while preventing the fault from escalating and protecting equipment and personnel safety. When an electrical component exhibits abnormal operating conditions, it issues an alarm signal to alert operators to take timely action and prevent further faulting.

[0003] The casing of traditional relay protection devices primarily serves a basic protective function, preventing external physical impacts and dust intrusion. However, during device operation, the continuous operation of internal equipment generates a significant amount of heat. If this heat cannot be dissipated in time, the temperature inside the casing will rise rapidly. Prolonged exposure to high temperatures can severely damage internal electronic components, leading to accelerated electron migration, material degradation, and consequently, significantly reduced operating efficiency, even causing malfunctions and jeopardizing the stable operation of the power system.

[0004] To address this issue, the present invention provides an intelligent heat dissipation housing for a relay protection device. Utility Model Content

[0017] Beneficial effects

[0018] This utility model provides an intelligent heat dissipation housing for a relay protection device. Compared with the prior art, it has the following advantages:

[0019] 1. The intelligent heat dissipation housing of this relay protection device has the main components of the relay mounted and fixed on the mounting base. The threaded holes on the mounting base are used for corresponding bolt screwing to facilitate the fixing of the relay components. When the components generate heat, the cooling fan starts to draw in the cool air outside the housing body, so that the hot air inside the housing body can rise smoothly and carry away the generated heat through the upper through hole.

The lower dust cover and the upper dust cover are mainly used to prevent dust and foreign objects from entering.

[0020] 2.

The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0028] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] Reference Figures 1 to 4 This application provides an intelligent heat dissipation housing for a relay protection device, including a housing body 1. A heat dissipation assembly 2 is disposed inside the housing body 1. The heat dissipation assembly 2 includes a mounting base 21, which is fixedly connected to the bottom of the inner wall of the housing body 1. A lower through-hole 23 is formed on the bottom side wall of the housing body 1, and an upper through-hole 24 is formed on the top side wall of the housing body 1. A cooling fan 25 is fixedly installed between the inner walls of the lower through-hole 23. A threaded hole 22 is formed inside the mounting base 21. A lower dust cover 26 is fixedly connected to the bottom of the housing body 1, and an upper dust cover 27 is fixedly connected to the top of the housing body 1.

[0030] In specific implementation: The main components of the relay are installed and fixed on the mounting base 21. The threaded holes 22 on the mounting base 21 are used for corresponding bolt screwing to facilitate the fixing of the relay components. When the components generate heat, the cooling fan 25 starts to draw in the cold air outside the outer shell 1, so that the hot air inside the outer shell 1 can rise smoothly and carry away the generated heat through the upper through hole 24. The cold air can also be continuously and smoothly replenished to form a circulation and thus generate a good heat dissipation effect. The lower dust cover 26 and the upper dust cover 27 are mainly used to prevent dust and foreign objects from entering.

[0031] Reference Figures 1 to 4 In one aspect of this embodiment, heat dissipation fins 28 are fixedly connected to the top and bottom of the outer casing 1. Ventilation holes 29 are provided inside the outer casing 1. Hollowed-out grooves 210 are provided on both sides of the outer casing 1, and a layer of dustproof mesh is fixedly connected to the outside of the hollowed-out grooves 210.

[0032] In specific implementation: heat dissipation fins 28 are designed on the outer shell body 1 to increase the heat dissipation area, so as to promote air circulation and heat exchange. Ventilation holes 29 can facilitate air circulation to dissipate heat inside the side wall of the outer shell body 1. Hollow grooves 210 are used to allow air to flow in from both sides of the outer shell body 1 to accelerate air circulation inside the outer shell body 1 and facilitate heat dissipation. Dustproof mesh on both sides is used to prevent dust from entering.

[0033] (Place high-heat-generating components as close to the casing as possible to shorten the heat conduction path. At the same time, avoid components blocking each other, as this will affect heat dissipation. Use thermally conductive materials such as thermal grease or thermal pads to connect the heat-generating components to the casing to reduce thermal resistance and improve heat conduction efficiency. The thermal grease should be applied evenly to the contact surface between the heat-generating component and the casing. The thickness and hardness of the thermal pad should be selected according to the actual situation to ensure good contact and thermal conductivity. Alternatively, a heat-dissipating coating, such as a ceramic heat-dissipating coating, can be applied to the surface of the casing body 1. This coating can improve the heat dissipation efficiency of the casing, dissipating heat to the surrounding environment more quickly through radiation and convection.)

[0034] All electrical devices in this plan are powered by an external power source.

[0035] Working principle: The core components of the relay are all mounted and fixed on the mounting base 21. The mounting base 21 has pre-drilled threaded holes 22, and the relay components are screwed in using matching bolts to ensure a secure installation. When the components generate heat during operation, the cooling fan 25 is activated, rapidly drawing in cool air from outside the housing 1. Due to the principle of natural upward movement of hot air, the hot air inside the housing 1 carries the heat and is exhausted through the upper perforation 24. Simultaneously, fresh cool air is continuously replenished, forming an efficient air circulation that significantly improves heat dissipation.

[0036] To prevent dust and foreign objects from entering the interior of the main body 1, a lower dust cover 26 and an upper dust cover 27 are specially designed. In addition, heat dissipation fins 28 are designed on the surface of the main body 1, significantly increasing the heat dissipation area and further enhancing heat exchange efficiency. The layout of the ventilation holes 29 guides airflow between the side walls of the main body 1, effectively promoting heat dissipation from the side walls. The perforated grooves 210 facilitate rapid airflow from both sides of the main body 1, accelerating air circulation within the main body 1 and comprehensively improving heat dissipation performance.

[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0038] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
