Overview

Concrete curing often involves high internal temperatures caused by cement hydration. Excessive heat can lead to cracks and compromised structural integrity. TVC Active Cooling solves this challenge by combining thermoelectric (Peltier) modules with a highly conductive aluminum vapor chamber (ALVC). This system actively extracts heat from large concrete pours, promoting uniform temperature control and helping prevent cracks.

Active thermal solution: - Cold temperature is generated from the TVC unit and the cold temperature is transferred to the concrete via the aluminum vapor chamber. - Direct cooling/Active cooling is provided in this system. - A faster cooling rate could be achieved via the TVC system.

Key Benefits

  • Reduced Risk of Cracking
    By lowering the peak hydration temperature, TVC Active Cooling minimizes stress differentials and reduces the likelihood of cracks forming in mass concrete.

  • Active & Efficient Cooling
    Thermoelectric modules can actively cool concrete to near or below ambient temperature, ensuring faster heat dissipation compared to passive methods.

  • Lightweight Aluminum Vapor Chamber
    The ALVC core offers rapid heat transfer, compact design possibilities, and minimal weight impact on construction sites.

  • Lower Water Usage
    Unlike traditional cooling approaches that often require extensive water circulation and chiller systems, TVC Active Cooling typically requires little to no water, minimizing resource usage and on-site logistics.

  • Flexible & Scalable
    Easily adapt the number of thermoelectric modules and ALVC placements to suit different project sizes or temperature control requirements.

How It Works

  1. Aluminum Vapor Chamber
    The ALVC is embedded or installed in direct contact with the concrete, drawing out interior heat.
  2. Thermoelectric (Peltier) Modules
    When powered, they boost cooling capacity by rapidly transporting heat away from the ALVC.
  3. Heat Dissipation
    Heat is released through heat sinks or fans, venting safely to the ambient environment.
  4. Adaptive Operation
    For moderate cooling needs, run the system in passive mode (modules off). For high thermal loads, switch on the thermoelectric modules for rapid heat extraction.

DemoKit Test Highlights

DemoKit Evaluation for TVC module

  • DemoKit Evaluation – Hot Water Test

    We assessed the TVC (Thermoelectric Vapor Chamber) system’s cooling performance by introducing approximately 1 liter of water at 66.2°C. With 30W of input to the thermoelectric modules, the TVC actively extracted heat from the hot water over 77 minutes, reducing the temperature to 32.1°C – a 34.1°C drop.

    • Cooling Rate: ~0.443°C/min
    • Active vs. Passive: The active thermoelectric mode was about 14% more efficient than passive cooling, highlighting the significant benefit of powering the Peltier modules.
    • Key Takeaway: Even under demanding conditions, the TVC system can rapidly lower water (and thus concrete) temperatures with minimal energy input, demonstrating its potential to effectively manage hydration heat in mass concrete applications.
