Thermal Engineer - บริษัท ฟรีเจล เอเชีย แปซิฟิก จำกัด

Scope of Job

The Thermal Engineer is responsible for the thermal management, analysis, and optimization of cooling system products. The role focuses on ensuring that products achieve maximum heating/cooling efficiency while maintaining reliability, performance, and compliance with engineering standards throughout the product development lifecycle.

Key Responsibilities:

• Perform thermal modeling, calculations, and simulations (1D & 3D) to analyze and optimize system performance.
• Support refrigeration cycle design, including selection and sizing of compressors, evaporators, and condensers.
• Select and evaluate electrical and mechanical components (e.g., sensors, motors, relays) for thermal performance and system integration.
• Prepare and maintain engineering documentation, including test reports, work instructions, and design records.
• Evaluate and recommend materials (e.g., insulation, refrigerants) based on thermal conductivity and performance requirements.
• Conduct and support thermal testing and validation, including the use of sensors and data logging equipment.
• Collaborate with Product Development and cross-functional teams to improve product efficiency and reliability.
• Ensure designs align with relevant industry standards and testing requirements (e.g., AHRI, ASHRAE, DOE)

• Bachelor’s Degree in Mechanical Engineering or related field.
• Minimum 1 year of experience in thermal engineering or related field (fresh graduates are welcome).
• Knowledge of Thermodynamics and Heat Transfer principles.
• Understanding of Fluid Mechanics, including pressure drop and flow characteristics (laminar vs. turbulent).
• Basic understanding of refrigeration systems and thermal fundamentals.
• Familiarity with AHRI, ASHRAE, and DOE standards is an advantage.
• Basic proficiency in simulation tools (thermal / CFD).
• Proficient in Microsoft Excel for data analysis and BOM management.
• Ability to work with 3D CAD software (e.g., SolidWorks).
• Hands-on experience with thermal instrumentation (e.g., sensors, data loggers) is a plus.
• Good command of English (reading and writing).
