# Industrial Specification: Thermal Control Unit

## 1. Technical Definition
A component within a Thermal Management System that regulates temperature by controlling heating, cooling, or heat transfer processes.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **283-353 K (10-80°C) with heat transfer coefficient of 50-200 W/m²·K**. Failure boundary: **Thermal stress exceeds yield strength of 316L stainless steel (205 MPa at 373 K) or coolant flow drops below 0.1 m/s causing laminar flow**, Mechanism: **Thermal fatigue from cyclic temperature differentials exceeding 50 K/min, or fouling resistance exceeding 0.0005 m²·K/W reducing heat transfer efficiency below 60%**.

### 2.1 Analytical Physics Model
Governed by the **Heat Sterilization F0 Lethality Model**:

> **Primary Equation**: $F_0 = \int_{0}^{t} 10^{(T-121.1)/z} dt$  
> **Engineering Impact**: Validates microbial reduction integrity for aseptic packaging.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| T | Process Temp (°C) | **$T \in [10-80°C]$ °C** (Per `temperature_range`) |
| t | Exposure Time (min) | Engineering Constant |
| z | Z-value | **10 °C** (Standard for *C. botulinum*) |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
