Regarding the Wewon Tech’s benchtop thermal forcing system, What is the difference between Wewon Tech’s vortex tube and other brands of vortex tubes ? The vortex tube whiched used by Wewon Tech’s benchtop thermal forcing system perfectly combines the two parameters of calibrated vortex tube refrigeration performance, pursuing low temperature and pursuing high cooling efficiency ratio. It not only avoids ignoring the cooling efficiency ratio due to the pursuit of the low temperature effect of the air-conditioning outlet, but also avoids ignoring the low temperature effect due to the one-sided pursuit of the cooling efficiency ratio.

The vortex tube which used by Wewon is very reliable. It can be preset and is an easily controlled cooling tool. The vortex tube converts compressed air into two streams, a cold stream and a hot stream. It has no moving parts with a simple structure. Meanwhile, The cost is cheap. The characteristics of the vortex tube for Wewon Tech’s benchtop thermal forcing system are as follows:
Wewon Tech’s vortex tube can generate air flow with temperature from -104 °F (-40 °C) to +250 °F (+230 °C). The cooling power can reach 2800 Btu/H (630 Kcal/H). The air flow can reach 35 SCFM (990 SLPM). Vortex tube for Wewon Tech’s benchtop thermal forcing system has no moving parts, portable, lightweight and the cost is cheap.
Wewon Tech’s vortex tube has No electricity, Freon or chemical refrigerants are needed, only filtered industrial compressed air is used. There is no danger of sparks, no wireless/radio frequency interference. Instant on/off, easy to control, refrigeration does not produce any waste.
Vortex tube has no need to clean up residues, no need to clean parts. It is reliable operation, maintenance-free, durable stainless steel structure. The input compressed air volume is 10, 15, 25, and 35 SCFM (280, 420, 700, 990 SLPM). It can produce up to 2500 Btu/H (630 Kcal/H) cooling capacity.
Use only manual knob and thermometer to adjust the cooling outlet temperature. If the inlet pressure and temperature of the compressed air remain unchanged, the outlet temperature of the vortex tube will remain constant within the range of ±0.6°C.
Thermal Forcing System

Refrigeration coefficient is an important parameter affecting the performance of vortex tube. The refrigeration coefficient (cooling efficiency ratio) refers to the percentage of the compressed air input to the vortex tube to the output cold air. The total amount of compressed air is the denominator, and the amount of cold air less than the total amount of compressed air is the molecule. The lower the coefficient of refrigeration, the lower the temperature of the cool air.

Coefficient coefficient also depends on the type/model of vortex generator in the vortex tube. For example: “high refrigeration coefficient type” or “low refrigeration coefficient type” vortex generator. Vortex generators with a high coefficient of refrigeration (greater than 50%) are used in most industrial applications. The high refrigeration coefficient vortex tube easily reduces the compressed air temperature at room temperature by 50-90°F (28-50°C).

High coefficient of cooling can provide more cold air, but can not output extremely low temperature. The combination of the output cold air flow and the cold air temperature in the high refrigeration coefficient working mode can produce the maximum cooling capacity, or the maximum Btu/H (Kcal/H). A low refrigeration coefficient (less than 50%) means that a small amount of cold air can be generated at a lower temperature (low temperature can reach -40°F/-40°C). Simply put, the less cool air is produced, the colder the cool air is.

We should remember that the maximum cooling capacity (also called maximum cooling capacity or cooling capacity) is produced in a vortex tube with a high coefficient of refrigeration. The following table shows the heating and cooling values of Wewon Tech’s vortex tube under different inlet pressures and cooling efficiency ratios. In the table, the upper area represents the temperature drop of the colder side °F, and the lower area represents the temperature rise of the hot air end °F

benchtop thermal forcing system

Wewon Tech’s benchtop thermal forcing system use the vortex tube to perform high temperature or low temperature test for different test samples. What is the Vortex Tube ? The vortex tube is a kind of energy separation device with very simple structure, which is composed of the separation orifice of the nozzle, vortex room and the cold and hot tube at both ends. The compressed gas expands in the nozzle and then enters the vortex tube along the tangential direction at a high speed. When the airflow rotates at high speed in the vortex tube, It is separated into two parts of the airflow with different temperatures after the vortex transformation. The air in the center is cooler, while the air in the outer part is hoter. According to the needs of application examples, the ratio of cold and hot flow can be adjusted to obtain the best cooling effect or heating effect.
