[0002] A searchlight is a strong light used to illuminate distant targets. It is usually used in ships, airplanes, police vehicles and other occasions. By placing the searchlight at a high place, it helps people see the target clearly at night or in bad weather conditions, thereby improving safety. The interior of a searchlight is usually composed of lamp beads, circuit boards and aluminum substrates. However, due to the high power of the searchlight, its lamp beads will generate a lot of heat when in use. Although the composite aluminum substrate has good thermal conductivity, the heat may accumulate at the junction of the composite aluminum substrate and the searchlight housing, which may cause the circuit boards and lamp beads inside the composite aluminum substrate to burn out, reducing the overall service life of the device.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a technical solution, a composite aluminum substrate for a searchlight, comprising: a composite aluminum substrate group 1, lamp beads 2 and mounting holes 3, the top of the composite aluminum substrate group 1 is connected with a circuit board through a heat-conducting adhesive, and the top of the circuit board is welded to the bottom of the lamp beads 2, the circuit board can be connected to the lamp beads 2, the lamp beads 2 are installed on the top of the composite aluminum substrate group 1 at equal intervals, and the mounting holes 3 are opened at the four corners of the top of the composite aluminum substrate group 1.

[0022] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The bottom sides of the composite aluminum substrate group 1 are evenly connected with support heat dissipation mechanisms 4, and the support heat dissipation mechanisms 4 include hollow columns 41. The hollow columns 41 can guide external airflow to the outside of the composite aluminum substrate group 1. The hollow columns 41 are aluminum tubes with a hollow internal design, and the top of the hollow columns 41 is connected to the bottom of the composite aluminum substrate group 1 by bolts. The aluminum tube can increase the thermal conductivity of the hollow columns 41, and the bolt connection method can facilitate the disassembly and maintenance of the hollow columns 41. The top of the hollow columns 41 is connected to the bottom of the composite aluminum substrate group 1.

[0023] One end of the hollow column 41 is connected to an air inlet pipe 42, and the outside of the air inlet pipe 42 is connected to a wide-mouth pipe 421. The wide-mouth pipe 421 is an inverted cone-shaped hollow pipe, and the inside of the wide-mouth pipe 421 is connected to a filter. The wide-mouth pipe 421 increases the effect of external airflow entering the inside of the hollow column 41, and the filter can filter the airflow. The top of one end of the hollow column 41 away from the air inlet pipe 42 is connected to an air collecting pipe 43, and the air collecting pipe 43 can collect the external airflow.

[0024] Exhaust ports 44 are arranged at equal intervals on the outside of the air collecting pipe 43. The exhaust ports 44 can disperse the airflow collected by the air collecting pipe 43 and discharge it to the outside of the composite aluminum substrate group 1 to dissipate heat from the outside of the composite aluminum substrate group 1. A thermal insulation pad 45 is connected to the top of the air collecting pipe 43. The thermal insulation pad 45 can prevent the composite aluminum substrate group 1 from causing damage to the outer shell 5. The thermal insulation pad 45 is a square rock wool board. The top of the thermal insulation pad 45 is in contact with the inner top of the outer shell 5. The thermal insulation pad 45 of the rock wool board can prevent heat energy from being transferred to the outer shell 5.

[0025] The composite aluminum substrate group 1 is provided with an outer shell 5 on the outside, which can protect the composite aluminum substrate group 1. Exhaust pipes 6 are evenly connected to the top of the outer shell 5, which can discharge the heat energy inside the outer shell 5. The exhaust pipes 6 are square aluminum tubes, and the inside of the exhaust pipes 6 is penetrated by a filter plate. The exhaust pipes 6 can discharge the heat energy inside the outer shell 5. The composite aluminum substrate group 1 should have one end with the lamp beads 2 facing downward, which is convenient for lighting, so that the outer shell 5 can only exhaust.

[0026] In this solution, the composite aluminum substrate group 1 is first connected to the housing 5, and a gap is created between the composite aluminum substrate group 1 and the housing 5 through the hollow column 41 at the bottom of the composite aluminum substrate group 1 to prevent heat from accumulating and being unable to be discharged. At the same time, the heat insulation pad 45 is used to prevent the hollow column 41 from transferring heat to the exhaust pipe 6. The device is then placed at a high place, and the airflow at the high place will enter the interior of the hollow column 41 through the wide-mouthed pipe 421, and then be discharged through the air collecting pipe 43 and the exhaust port 44, so as to dissipate heat inside the composite aluminum substrate group 1, and finally discharge the heat energy through the exhaust pipe 6 to complete the heat dissipation of the composite aluminum substrate group 1;

[0027] When the composite aluminum substrate group 1 is in use, the added supporting heat dissipation mechanism 4 can prevent the composite aluminum substrate group 1 from being directly installed on the outer shell 5, thereby preventing heat from not being able to flow normally. At the same time, the thermal insulation pad 45 can prevent the hollow column 41 from directly transferring heat energy to the inside of the outer shell 5 through good thermal conductivity. Finally, the external airflow is introduced through the supporting heat dissipation mechanism 4 to dissipate heat on the outside of the composite aluminum substrate group 1, thereby preventing heat accumulation caused by the heat energy generated by the lamp beads 2 when the composite aluminum substrate group 1 is in use, and preventing heat from damaging the internal components of the composite aluminum substrate group 1.
