Abstract
Description
Technical Field
[0001] This utility model relates to the field of headspace sampler technology, and in particular to a headspace heating device with rapid cooling function. Background Technology
[0002] In headspace sampling analysis, temperature control of the sample equilibrium furnace plays a crucial role in sample pretreatment. To ensure that samples reach thermodynamic equilibrium before injection, sample equilibrium furnaces are typically designed with a large heat capacity to maintain temperature stability. However, different types of samples have significantly different temperature requirements for the equilibrium furnace during analysis; some analytical methods require operation at high temperatures, while others require lower temperatures.
[0003] In current technology, when the sample analysis method needs to switch from high temperature conditions to lower temperature conditions, the sample equilibrium heating furnace relies on natural cooling or air cooling to lower the temperature. The cooling process is slow, which leads to a longer waiting time between detection tasks and seriously affects the overall detection efficiency.
[0004] Therefore, those skilled in the art have provided a headspace heating device with rapid cooling function to solve the problems mentioned in the background art. Utility Model Content

This device involves installing a serpentine cooling water pipe on the outer surface of the sample equilibrium heating furnace, while simultaneously installing a heat exchange coil inside the heat dissipation fins. This structural design facilitates heat exchange. The supply, return, and drain pipes create a closed-loop water circulation system connecting the serpentine cooling water, the heat exchange coil, and the water tank. This solution first cools the sample equilibrium heating furnace using water cooling, then dissipates the heat absorbed in the circulating water to the environment through a cooling fan and heat exchange coil. The combined operation of water cooling and air cooling significantly improves the cooling efficiency of the sample equilibrium heating furnace.
