Outdoor roof heat emitting device used in summer

Abstract

The invention discloses an outdoor roof heat emitting device used in summer. The outdoor roof heat emitting device comprises a base plate and cooling fins, and the base plate and the cooling fins are connected in a sheet inserting manner. T-shaped grooves are formed in the upper surface of the base plate. A fixing plate capable of sliding is arranged on the slotted side face of the base plate. One end of each cooling fin is matched with the corresponding T-shaped groove. Silicone grease films are arranged on the groove faces of the T-shaped grooves. A water storage layer is arranged in the base plate, and a trepanned face is arranged on the side face of the base plate. A water inlet is formed in the upper portion of the trepanned face, a water outlet is formed in the lower portion of the trepanned face, and the water inlet and the water outlet are closed through pistons. At least one stirring device is arranged in the water storage layer and connected with the bottom of the base plate. A base plate and cooling fins are adopted in an existing traditional heat dissipation structure for heat dissipation, the base plate makes contact with a heat source and transmits the heat to the cooling fins in a heat conduction manner, the cooling fins bring heat away according to contact with air, but in the actual using process, for a large radiator, the bottom of the base plate is heated unevenly.

Description

technical field [0001] The invention relates to a heat dissipation device, in particular to an outdoor roof heat output device used in summer. Background technique [0002] The heat dissipation method refers to the main way the radiator dissipates heat. In thermodynamics, heat dissipation is heat transfer, and there are three main ways of heat transfer: heat conduction, heat convection and heat radiation. The transfer of energy by itself or when matter comes into contact with matter is known as heat conduction, and it is the most common form of heat transfer. Convection refers to the transfer of heat by a moving fluid that carries heat away. Thermal radiation refers to the transfer of heat by ray radiation, the most common of which is solar radiation. These three heat dissipation methods are not isolated. In daily heat transfer, these three heat dissipation methods all occur at the same time and work together. In fact, any type of radiator basically uses the above three ...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is the welding structure of the substrate and the heat sink, the heat sink is difficult to clean, and the heat sink cannot be replaced independently according to the change of the environment, and the bottom of the substrate is heated unevenly, resulting in uneven heat transfer to the heat sink. The purpose is to provide an outdoor roof heat output device used in summer, and solve the structure of the welding of the substrate and the heat sink. The heat sink is difficult to clean, and the heat sink cannot be replaced separately according to the change of the environment. The problem of uneven heat on the chip
