Abstract

The invention discloses a heat dissipation device and a lamp. The heat dissipation device comprises a heat conduction plate, a plurality of fins and a fan, the heat conduction plate is used for exchanging heat with a heating element and is provided with a heat dissipation area and an installation area, the heat conduction plate is provided with an overflowing opening, and the overflowing opening is located in the installation area; the multiple fins are arranged on the heat conduction plate at intervals, a heat exchange air duct is formed between every two adjacent fins, all the fins are located in the heat dissipation area, and one end of each heat exchange air duct faces the installation area; the fan is installed on the heat conduction plate, the fan is located in the installation area,and the fan is used for driving airflow to pass through the overflowing opening and flow through the heat exchange air duct. According to the heat dissipation device, through the arrangement of the fan, under the condition that the fan rotates, the air volume can be increased, convection is forced, and the better heat dissipation effect is achieved.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to a heat dissipation device and a lamp. Background technique [0002] Heat dissipation has always been a major factor affecting the performance of lamps, especially for lamps with high heat dissipation. Excessive temperature may cause serious damage to equipment or products. The design methods pursued by heat dissipation products are generally divided into three categories, natural cooling, air cooling, cooling through media such as refrigerant, water cooling, and so on. Among various cooling methods, engineers also have coordinated designs such as refrigerant and air cooling, natural cooling and air cooling, and so on. However, the design of the existing air cooling method is unreasonable, resulting in poor heat dissipation effect of the lamp. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention discloses a heat dissi...
