Description

Heat radiator for intelligence box

Technical Field

The utility model relates to a heat dissipation field, in particular to heat abstractor of intelligence box.

Background

The heat dissipation device of the existing intelligent device is usually placed in the heat dissipation device together with a heating unit (circuit board), or the heat dissipation device is not additionally arranged at all, and the condition is usually in the air cooling working condition: at the moment, air openings are oppositely formed in two sides of the intelligent device shell. The heat dissipation mode is simple and effective, and the defects are as follows: (1) the intelligent device is additionally provided with a fan to guide airflow, so that the cost is increased, and the volume of the intelligent device is increased; (2) if the intelligent device is in a closed space and a plurality of intelligent devices operate for a long time, the air cooling effect cannot be expected due to the rise of the whole environment temperature.

The intelligent device also has a heat dissipation mode of water cooling, and the intelligent device has the defects that a water cooling pipeline which is long enough needs to be specially arranged, the sealing measure requirement is high, the cost is increased, and the requirement on the construction process is high.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's shortcoming and not enough, provide a heat abstractor of intelligence box.

The purpose of the utility model is realized through the following technical scheme:

a heat dissipation device of an intelligent box comprises a shell body and a circuit board arranged in the shell body; the heat dissipation device comprises heat-conducting silicone grease and a bottom plate; one surface of the heat-conducting silicone grease is adhered to a heating element of the circuit board, and the other surface of the heat-conducting silicone grease is in direct contact with the bottom plate.

The intelligent box further comprises a left hanging plate and a right hanging plate, wherein the left hanging plate and the right hanging plate are used for fixing the left side and the right side of the bottom plate respectively, and the bottom plate and the shell body form a closed space.

The outer surface of the bottom plate is also provided with more than one row of parallel radiating fins. The heat radiation effect of the bottom plate is enhanced by the heat radiation bottom plate.

The intelligent box further comprises a wall hanging support, the wall hanging support is arranged on the outer side of the bottom plate, and the left end and the right end of the wall hanging support are fixed to the left side and the right side of the bottom plate respectively. The purpose of setting up hanging support: firstly, conveniently fix the intelligent box at wall body or other mounted positions, secondly avoid radiating bottom plate to expose outside.

The casing body includes rear panel, integrated into one piece casing, and wherein, the rear panel sets up M stopper, and the inboard correspondence of integrated into one piece casing sets up N limit stop, and N is 2M, and M is greater than or equal to 1. In order to meet the high requirement (not more than 0.1mm) of the gap of partial users, the front panel and the shell are made into a whole body, and the gap of the front panel is ensured; the rear panel is provided separately. Simultaneously every stopper corresponds and sets up two limit stop, and the back panel is convenient for the assembly of integrated into one piece casing, and the location is inaccurate when preventing the assembly.

And reinforcing ribs are arranged on the inner side of the rear panel.

Compared with the prior art, the utility model, following advantage and beneficial effect have:

1. the utility model discloses a heat abstractor guides the heat dissipation work of intelligence box to intelligence box outside, has two advantages like this: firstly, the work of electronic components in the intelligent box is not interfered; secondly, the components of the heat dissipation device can be arranged to be larger under the same conditions.

2. The utility model discloses a heat abstractor volume is less, and the cost is lower.
