Cast aluminum heater rapid cooling air channel

Abstract

The invention discloses a cast aluminum heater rapid cooling air channel which comprises a first flow channel and a second flow channel. The first flow channel and the second flow channel are arrangedon the two sides of the interior of a cylinder body of a heater cylinder, and an air cavity is formed in the middle of the interior of the cylinder body of the heater cylinder. The opposite ends of the first flow channel and the second flow channel correspondingly penetrate into the air cavity, the back-to-back ends of the first flow channel and the second flow channel correspondingly penetrate through the side surfaces of the two ends of the heater cylinder, the first flow channel and the second flow channel are both arranged in a spiral mode, and the upper surface of the heater cylinder isconnected with an air inlet pipe. And the air inlet pipe is correspondingly connected with the interior of the air cavity. According to the invention, the air body flow channel is arranged in a bidirectional spiral manner, and the hollow air cavity is formed in the middle of the air body flow channel so that bidirectional air-cooling heat dissipation operation can be realized, a backflow generatedwhen the air body passes through the air channel is small, rapid heat dissipation operation can be realized, and the air inlet pipe is arranged at the position corresponding to the air cavity in a penetrating manner and can be connected with air supply equipment to realize synchronous heat dissipation from the heater to two sides.

Description

technical field [0001] The invention relates to the field of heat dissipation of cast aluminum heaters, in particular to a rapid cooling air duct of cast aluminum heaters. Background technique [0002] Cast aluminum heater is a metal casting heater with high thermal efficiency and uniform heat distribution. The structure of cast aluminum heater: the cast aluminum heater uses a tubular electric heating element as a heating element, which is bent and formed. It is required to specially design its arrangement, fix it inside the mold, use high-quality national standard aluminum ingots as raw materials, and melt and cast electric heaters. [0003] The main structure of the cast aluminum heater itself is aluminum, which has a high thermal conductivity. When the heater stops working, it relies on the natural heat dissipation from the outer surface to dissipate heat. The heat dissipation rate is low and cannot quickly reach the cooling state.

Problems solved by technology

[0003] The main structure of the cast aluminum heater itself is aluminum, which has a high thermal conductivity. When the heater stops working, it relies on the natural heat dissipation from the outer surface to dissipate heat. The heat dissipation rate is low and cannot quickly reach the cooling state. The existing heating An air duct is added inside the structure of the device for auxiliary heat dissipation. Although the heat dissipation can be accelerated to a certain extent, the layout and direction of the air duct are likely to cause air backflow to affect heat dissipation, and the efficiency of heat dissipation needs to be further improved.
