[0018] The present utility model will be further described below with reference to the drawings:

[0019] Referring to the attached drawings: This relay base with heat dissipation function includes a relay base body 1. On the assembled back surface of the relay base body 1, there is a fixing plate 3 connected through an isolation block 2. The isolation block 2 is cross-shaped and divides the gap between the relay base body 1 and the fixing plate 3 into four independent areas. In each independent area on the assembled back surface of the relay base body 1, there is an installation cavity 11 for setting a detachable air passage component 4. The air passage component 4 is used to discharge the heat generated by the operation of the electrical components in the relay base body 1 and prevent impurities from entering the relay base body 1. On the isolation block 2, there is a detachable fan component 5 corresponding to each independent area. The fan component 5 accelerates the air flow during heat dissipation. The beneficial effect of the present utility model is that the air passage component 4 is used to achieve heat dissipation in a cold and hot alternating manner, that is, conducting the outside air into the relay base body 1, then taking away the heat and discharging it. The detachable setting is because the impurities that are blocked from entering will adhere to the air passage component 4. When there are more impurities, it will affect the heat dissipation effect of the air passage component 4. Therefore, the detachable method can disassemble the air passage component 4 and clean it to ensure the heat dissipation effect of the air passage component 4. The fan component 5 is used to accelerate the air flow to improve the heat dissipation effect.

[0020] The air passage component 4 includes an air passage part 41 and a positioning part 42 for quickly defining the final assembled position of the air passage part 41 in the installation cavity 11. The configuration of the air passage part 41 matches the configuration of the installation cavity 11 and is provided with a number of air passage channels 41-a distributed in an array. The positioning part 42 is arranged on the back surface of the air passage part 41 and has a breathable opening 42-a that communicates with the air passage channels 41-a without obstructing the air flow. The air passage part 41 is a block with a configuration matching that of the installation cavity 11 and has a thickness that meets the depth of the installation cavity 11 to realize the setting of the air passage channels 41-a. The positioning part 42 is used to quickly define the final assembled position of the air passage part 41 in the installation cavity 11 on the one hand, and on the other hand, when the air passage part 41 is arranged in the installation cavity 11, it is located outside the installation cavity 11, so it can also be used as a gripping part to facilitate the user to take out the air passage component 4. The positioning part 42 is a frame body with a breathable opening 42-a.

[0021] A filter screen 6 for preventing impurities from entering the air passage channels 41-a is arranged in the breathable opening 42-a. The filter screen 6 filters the impurities attached to the air to avoid the impurities adhering to the air passage channels 41-a or the electrical components.

[0022] The installation cavity 11 is provided with a locking cavity 12 communicating with the installation cavity 11 on the assembly back surface. The upper end of the positioning part 42 has a notch 42-b, and a pressing buckle 7 that is locked and cooperated with the locking cavity 12 is arranged in the notch 42-b. Such a setting can lock the air venting component 4 in the installation cavity 11. The pressing buckle 7 is an elastic part, and when it is in a preset shape, it is clamped in the locking cavity 12 to generate a resistance to prevent the air venting component 4 from moving. When unlocking, only need to press the pressing buckle 7 to change its preset shape, and when its preset shape changes, it cannot be clamped in the locking cavity 12.

[0023] The fan assembly 5 includes a connecting part 51 provided with a fan and an assembly insertion part 52 detachably connected to the isolation block 2. An extension body 53 is arranged between the connecting part 51 and the assembly insertion part 52. The isolation block 2 is provided with an assembly insertion channel 21 defining an assembly guide. The assembly insertion part 52 is inserted into the assembly insertion channel 21. The assembly insertion channel 21 is provided with a side opening 22 on the isolation block 2 that does not hinder the extension body 53 from following the assembly movement of the assembly insertion part 52. The connecting part 51 is a frame body, that is, it has an inner installation area, which is convenient for the installation of the fan. The assembly insertion part 52 is used to realize the connection with the isolation block 2, that is, it is inserted into the assembly insertion channel 21 so that the fan can stably exist at the front end of the entrance of the air venting channel 41-a. The extension body 53 extends the service length of the connecting part 51 and does not affect the constraint of the assembly insertion channel 21 on the assembly insertion part 52, so that the connecting part 51 can extend to the front end of the air venting channel 41-a to achieve accelerated heat dissipation.

[0024] The assembly insertion channel 21 is divided into a sliding section 21-a and a locking section 21-b along the assembly guide. The assembly insertion part 52 has a clearance fit with the sliding section 21-a and an interference fit with the locking section 21-b. Such a setting enables the assembly insertion part 52 to be inserted into the assembly insertion channel 21 along the assembly guide from the sliding section 21-a. The part of the assembly insertion part 52 located in the assembly insertion channel 21 has a clearance fit with the sliding section 21-a, that is, the assembly insertion part 52 can slide along the assembly guide. When the assembly insertion part 52 slides to the locking section 21-b, it has an interference fit with it, so that the assembly insertion part 52 is locked in the locking section 21-b. Such a connection and assembly do not require tools or additional parts such as screws and bolts, and are suitable for quick assembly and convenient assembly.

[0025] The fitting clearance between the assembly insertion channel 21 and the assembly insertion part 52 gradually decreases along the assembly guide, and the change of its channel width is linear, making the insertion process relatively stable and avoiding the phenomenon of jamming during the connection and assembly.

[0026] The fixing plate 3 is provided with a guide groove 31 for guiding the hot air to be discharged around on the front surface close to the fan assembly 5. Such a setting can accelerate the hot air to leave the gap area, that is, achieve rapid discharge.

[0027] Although the present utility model has been illustrated and described with reference to the preferred embodiments, those of ordinary skill in the art should understand that various changes in form and detail may be made within the scope of the claims.
