Featured Examples
Data Center Cooling
Models the cooling system of a data center. The system consists of two separate water loops: a chilled water loop and a condenser water loop. The chilled water loop absorbs heat from the server farm and transfers it to the condenser water loop. The condenser water loop rejects this heat to the environment using a cooling tower.
Heat Transfer in a Thermal Liquid Pipe
How changes in mass flow rate, environment, and flow direction impact heat transfer in a pipe. These factors are important when designing cooling systems or heat exchangers. This example uses the Simscape™ Fluids™ Pipe (TL) block. For more information on pressure loss and flow rate in a pipe, see Pressure Loss and Mass Flow Rate in a Thermal Liquid Pipe.
Hydraulic Oil System with Thermal Control
A hydraulic oil system with a thermal control using Simscape™ Fluids™ Thermal Liquid blocks. The hydraulic oil system consists of an oil storage tank represented by the Tank (TL) block with two inlets, a pump represented by a Mass Flow Rate Source (TL) block, and pipelines represented by Pipe (TL) block.
Parameterize a Simple Heat Exchanger
How different fluids and geometries affect the performance of a heat exchanger. This example uses Simscape Fluids heat exchanger blocks and the number of transfer units (NTU) method to calculate heat transfer. For more information on calculating heat transfer by using the log mean temperature difference (LMTD), see EV Battery Cooling System Design or Heat Transfer in a Thermal Liquid Pipe.
Refrigerant Modernization
Retrofit a Simscape™ cooling cycle that uses R410a to utilize R32, which is a refrigerant with a lower Global Warming Potential (GWP). The process involves modifying the nominal mass flow rate and refrigerant charge, while retaining the original evaporator and condenser specifications. For more information on designing a cooling cycle, see Model a Refrigeration Cycle and Refrigeration Cycle (Air Conditioning).
Residential Refrigerator
Models a basic refrigeration system that transfers heat between the refrigerant two-phase fluid and the environment moist air mixture. The compressor drives the R134a refrigerant through a condenser, a capillary tube, and an evaporator. An accumulator ensures that only vapor returns to the compressor.
Simple CPU Cooling System
A simple CPU cooling system consists of a heat sink, a CPU fan, and fan controllers. The heat generated by the CPU is transferred to the heat sink by conduction and it is dissipated to the cooling air by forced convection mechanism. The heat sink is a parallel plate fin with rectangular fins between the plate fins. The CPU fan moves air across the heat sink by drawing air into the case grille from the outside and ejecting warm air from inside. The fan controller unit includes three control levels, representing a 3-speed switch, according to the CPU temperature. For lower CPU temperature, the fan speed is decreased and for higher temperature it is increased.
Stratified Hot Water Storage Tank Example
Model a hot water storage tank with temperature variations from top to bottom. The tank has a cold water inlet on the bottom and a hot water outlet on the top. This design allows the top of the tank and the outgoing water to remain hot even as the tank refills and cools the bottom of the tank.
