Overview
The HC-FL-500 thermal cycling test chamber (also known as temperature cycling test chamber, cold hot cycling test chamber) is a precision environmental testing equipment used to simulate alternating high and low temperature environments for testing product reliability and material stability.
Product Details
Thermal cycle test chamber
HC-FL-500
1、 Core principle
By working together with the cooling system and heating system, the temperature is repeatedly cycled between high and low temperatures in a closed chamber according to a preset program.
• Temperature range: commonly -70 ℃~+180 ℃
• Temperature rate: standard about 5-15 ℃/min
Control accuracy: fluctuation ± 0.5 ℃, uniformity ± 2 ℃
2、 Main purpose
Test the tolerance of the product under thermal expansion and contraction stress, and quickly expose defects:
• Electronics: chips PCB、 Components and batteries (such as UN38.3 testing)
• Automobiles: components, sensors, wiring harnesses, onboard electronics
• Materials: metal, plastic, rubber, paint, adhesive
• Other: aerospace, military, communication, photovoltaic products
3、 Equipment structure
• Chamber: SUS304 stainless steel inner liner, double-layer insulation
• Refrigeration: Duplex compressor refrigeration, environmentally friendly refrigerant
Heating: Stainless steel finned heater
Wind circulation: Strong convection fan to ensure uniform temperature
• Control: PLC/touch screen, programmable loop (temperature, time, frequency)
• Safety: Over temperature protection, water shortage protection, leakage protection
4、 Difference from temperature shock box
• Hot cycle box: slow temperature change (minute level), focusing on long-term fatigue
• Temperature shock box: instantaneous temperature change (a few seconds), focusing on thermal shock
5、 Common specifications (volume)
• Small: 100L/225L (electronic components)
Medium size: 408L/500L (parts)
• Large: 800L/1000L+(whole machine, large components)

6、 Compliant with standards
National standard: GB/T 2423.1/2/22
• International: IEC 60068, MIL-STD, JESD22
Industry: UN 38.3 (batteries) ASTM
