AI Technical Summary

Technical Problem

Existing temperature test devices, particularly open temperature test tanks, face challenges in evenly distributing temperature throughout the chamber, especially in the corners, due to air from the air curtain outlet not easily reaching the back of the test chamber, leading to prolonged stabilization times.

Method used

The device incorporates an air passage within the test chamber that extends from the back to the intake port, creating negative pressure to facilitate uniform air distribution, and includes a plate-shaped member with air inlets and outlets to enhance airflow, allowing air to reach the back of the chamber efficiently.

Benefits of technology

This configuration significantly reduces the time required for the temperature inside the test chamber to stabilize at the set temperature, ensuring uniform temperature distribution without additional equipment.

Abstract

The present invention provides a temperature testing apparatus that can shorten the time it takes for the temperature inside the test chamber to stabilize at the set temperature. [Solution] The temperature testing apparatus 1A comprises an opening 3a, a blower mechanism, a mounting surface 4g, and an air passage. The opening 3a is provided in part of the partition wall separating the inside and outside of the test chamber 3, and is provided for loading the object to be tested into the test chamber 3 and for loading the object to be tested out of the test chamber 3. The blower mechanism has an air outlet 10a provided at the top of the opening 3a, an air intake 10b provided at the bottom of the opening 3a, and a blower 6 that sends air from the intake 10b to the outlet 10a, forming an air curtain A1 along the opening 3a. The mounting surface 4g is provided inside the test chamber 3 and is on which the object to be tested is placed. The air passage is located inside the test chamber 3, in a region on the opposite side of the mounting surface 4g from the opening 3a, passing below the mounting surface 4g to the intake 10b.
