What Is a Jet Cooler?
A jet cooler is a device that cools an object using vortex force. It is a compact cooling device that can be used in any location.
In addition to its small size, it has the following features:
- Environmentally Friendly
Other cooling systems use refrigerants such as chlorofluorocarbons, which can have a negative impact on the environment when released into the atmosphere. Jet coolers, on the other hand, are environmentally friendly because they only use compressed air. - Durable
Jet coolers have no sliding parts and a simple structure, making them highly durable with minimal breakdowns over time.
Uses of Jet Coolers
Jet coolers find applications in soldering processes.
Soldering is a method of joining components by melting and hardening an alloy of tin and lead (solder) with heat, primarily used in electronic components.
Lead-free solder, now preferred for its reduced impact on human health, tends to harden unevenly. This can result in product defects such as cracks. Jet coolers are used to ensure uniform cooling for consistent solder hardening.
Principles of Jet Coolers
Jet coolers utilize vortex force to generate cold air.
Initially, a compressor is employed to supply compressed air into the device. The compression stores energy and generates a powerful force.
The compressed air passes through a vortex generator within the equipment. Inside the generator, the air is released tangentially, resulting in high-speed rotation and vortex formation.
As the vortex rotates, centrifugal force comes into play, causing an increase in pressure and density. Following Boyle-Charles’ law, an increase in pressure and density results in higher temperature.
The vortex moves toward the outlet. During this movement, the temperature decreases at the center of the vortex as the air expands. Heat is released from the center outward, creating a temperature difference between the center and the outer region of the vortex. The cooler central air is expelled from the outlet and used for cooling purposes, while warmer outside air is discharged in the opposite direction.
By repeatedly supplying compressed air, creating a vortex, and segregating air based on temperature, consistent and efficient cooling is achieved.
