Product Specifications

Technical details and manufacturing context for Cooling Heat Exchanger or Chiller Unit

Definition
A critical component of the Coolant Management System responsible for regulating coolant temperature by transferring heat from the coolant to another medium (air, water, or refrigerant). It maintains optimal operating temperatures for machinery and processes, preventing overheating and ensuring system efficiency.
Working Principle
Operates through heat exchange principles: in a heat exchanger, hot coolant flows through tubes or plates while a cooler medium (air or water) absorbs heat; in a chiller unit, a refrigeration cycle (compression, condensation, expansion, evaporation) extracts heat from the coolant, typically using a refrigerant.
Common Materials
Copper, Aluminum, Stainless Steel
Technical Parameters
  • Cooling capacity, indicating the rate of heat removal from the coolant. (kW) Per Request
Components / BOM
  • Heat Exchanger Core
    Facilitates heat transfer between coolant and cooling medium.
    Material: Copper or Aluminum
  • Compressor
    In chiller units, compresses refrigerant to initiate the cooling cycle.
    Material: Steel or Cast Iron
  • Evaporator Coil
    Absorbs heat from the coolant in chiller units via refrigerant evaporation.
    Material: Copper
Engineering Reasoning
0.5-3.5 MPa (5-35 bar) at 5-40°C coolant temperature
Compressor discharge pressure exceeding 4.2 MPa (42 bar) or evaporator approach temperature dropping below 2°C
Design Rationale: Refrigerant flash gas formation in expansion valve causing liquid slugging in compressor scroll elements
Risk Mitigation (FMEA)
Trigger Coolant glycol concentration dropping below 30% by volume
Mode: Ice crystal formation on evaporator tubes causing refrigerant flow restriction
Strategy: Automated glycol concentration monitoring with 35% minimum setpoint interlock
Trigger Condenser fouling exceeding 0.00025 m²·K/W thermal resistance
Mode: Compressor head pressure rising above 3.8 MPa (38 bar) causing thermal overload trip
Strategy: Differential pressure monitoring across condenser with 15 kPa delta-P alarm threshold
