# Industrial Specification: Cooler

## 1. Technical Definition
A heat exchanger component within a lubrication system that removes excess heat from lubricating oil to maintain optimal operating temperatures.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-4.0 MPa (5-40 bar) at 20-90°C oil temperature with 10-100 L/min flow rate**. Failure boundary: **Thermal stress exceeding 250 MPa yield strength at 150°C differential temperature across tube-plate joints**, Mechanism: **Thermal fatigue from cyclic temperature gradients exceeding 80°C between oil inlet (90°C) and cooling medium (10°C), causing differential expansion stresses at brazed joints exceeding material endurance limit of 180 MPa for copper-nickel alloys**.

### 2.1 Analytical Physics Model
Governed by the **LMTD Logarithmic Mean Temperature Difference**:

> **Primary Equation**: $Q = U \cdot A \cdot \Delta T_{lm}$  
> **Engineering Impact**: Sizing validation for pasteurization and cooling tunnels.
