Understanding Heat Exchangers

2020/9/11Heat exchangers are devices designed to transfer heat between two or more fluids—i.e., liquids, vapors, or gases—of different temperatures. Depending on the type of heat exchanger employed, the heat transferring process can be gas-to-gas, liquid-to-gas, or liquid-to-liquid and occur through a solid separator, which prevents mixing of the fluids, or direct fluid contact.

New polymer films conduct heat instead of trapping it

2019/4/29In experiments, they found the films, which are thinner than plastic wrap, conduct heat better than ceramics and many metals, including steel. The team's results, published in the journal Nature Communications, may spur the development of polymer insulators

Turning the Tables: Thermally Conductive Plastics

2019/5/23Plastic polymers may replace metal as lightweight, flexible heat conductors in cars, refrigerators, and electronic devices. Polymers are usually the go-to material for thermal insulation. Think of a silicone oven mitts or a Styrofoam coffee cup, both items are manufactured from polymer-based materials that are excellent at trapping heat.

ultrasonic cleaning

The best part is the fact that ultrasonic cleaning can be used on a wide range of different equipment that are made of various materials such as metal, ceramic, rubber, plastic and glass. This leaves very little and enables individuals to actually clean away any sort of contaminants on such materials without having to struggle too much in the process at all.

A Low

A plastic-plate heat exchanger, which could be used as the cross exchanger, will be designed. Finally, an engineering analysis will be performed to estimate the impact of the plastic heat exchangers on the cost and energy-use of an advanced CO2 scrubber for a 500 MW pulverized-fuel power plant.

Heat Exchanger Analysis

Heat exchangers are ubiquitous components in energy systems. Some common examples are car radiators and refrigerator evaporators. In both cases, the heat exchanger is facilitating the transfer of heat, from one stream of fluid to another. From these examples, it

HeatTransfer Coefficients and Pressure Drops of The

In order to enhance the heat transfer coefficient of the fin used in the finned tube heat exchanger, newly designed fin surfaces, especially, with small diameter (≅4mm) pipes are developed. The experiments are made by the transient testing technique, and used the plastic fins scaling up 4 times of the actual metal fin size. The data of the heat transfer coefficient and the pressure drop are
