As shown in the figure, the computer control cable of the application integrates two cable bodies, and each cable body contains a plurality of core wires, thereby realizing complex signal transmission and connection of a plurality of devices. And because of the existence of the heat conducting mechanism, heat generated in the use process of the cable body can be transferred into the heat radiating channel and is taken away by heat radiating airflow in the heat radiating channel. Because the plurality of mounting through holes are distributed at equal intervals, a complete heat dissipation cycle is formed between two adjacent mounting through holes. In order to avoid the mutual interference of the air flows, a plurality of cooling fans of the same functional unit are used for air intake, specifically, for example, a plurality of functional units are provided, the cooling fan of the first functional unit is used for air intake, the cooling fan of the second functional unit is used for air outlet, the cooling fan of the third functional unit is used for air intake, the cooling fan of the fourth functional unit is used for air outlet, and so on, thereby realizing the circulation of the cooling air flow in the cooling channel and realizing the effective heat dissipation.

Therefore, the heat dissipation air flow cannot be shunted and wasted by the first through hole, and the cable bodies at the two sides of the detection space do not have the heat dissipation air flow to assist in heat dissipation due to the existence of the ventilation groove, but can naturally dissipate heat through the ventilation groove.
In addition, after the cable is used for a long time, the functional unit of the application may be damaged, the heat dissipation channel is blocked by dust accumulation, and the like, and the structure of the application in the cable body may be changed along with the aging of the cable, so that compared with an initial state, abnormal heating, and the like.

In the detection state, one of the heat dissipation spaces is in air inlet, the other heat dissipation space is out of air (the wind shield can avoid interference between two airflows), so that one of the two first temperature sensors actually detects the temperature of the starting end of the heat dissipation airflow, and the other detects the temperature of the tail end of the heat dissipation airflow, and therefore the heat dissipation effect can be judged according to the temperature difference, and whether the whole system operates normally or not. In addition, the second temperature sensor can also be inserted into the corresponding detection groove, so that the heating condition of the position of the cable body without heat dissipation and airflow heat dissipation is detected, whether the heating condition of the cable body is normal is judged, and the first temperature sensor and the second temperature sensor can be detected more accurately due to the matching of the first push plate and the second push plate with the first limiting cylinder and the second limiting cylinder.
