What is a wall fin?
Description. Wall fin enclosure is used to provide an esthetically appealing covering for the heating element while improving convection for increased performance. Sigma offers a wide range of wallfin enclosure styles to satisfy any architectural requirement. Styles include standard, freestanding, slim and security.
What is a tube radiator?
Finned tube radiators are the most widely used heat exchange equipment in gas and liquid heat exchangers. It achieves the purpose of enhancing heat transfer by adding fins to a common base pipe. The base pipe can be made of a steel pipe; a stainless steel pipe; a copper pipe or the like.
What is finned tube heat exchanger?
Finned tubes are the main components of heat exchangers. They are a series of tubes where fins have been added on the outside to increase the contact area with the outside fluid, to exchange heat and between the fluid inside the tube and the fluid outside the tube.
What is a fin radiator?
A radiator consists of tubes with fins in between. The (hot) coolant passes through the tubes. The fins provide the heat transfer from the tubes into the air stream.
How many tubes are in a radiator?
A 1-Row Radiator has 1 row of tubes. A 2-Row Radiator has 2 rows of tubes. A 3-Row Radiator has 3 rows of tubes.
Do cabinet unit heaters have filters?
Quick-change permanent filters are removable without tools. Cleanable filters are standard. Sound dampening insulation on all front panels. Blower platform, blower, and blower motor on all sizes are removable as a single unit.
What is a forced flow heater?
In contrast to the circulation heater, a forced flow circulation heater is fitted with a secondary pump. This pump forces the fluid through the heater and achieves the potential temperature in half time. As a secondary component, a cooling system interacts with the heating system of your vehicle.
How are fins attached to tubes?
Fins are attached to the tubes by a tight mechanical bond through tension winding, soldering, brazing, or welding. For example, an aluminum fin can be applied to a stainless steel tube to maximize air cooling — a very common approach in the cooling industry.
What is fin efficiency?
Fin efficiency is defined as the ratio of actual heat flow of the fin to that which would be obtained with a fin of constant temperature uniformly equal to the base surface temperature, that is, one with infinite thermal conductivity.
What is fin tube radiation and how does it work?
Heating elements of Modine’s Fin Tube Radiation are copper tubes with aluminum fins. The aluminum fins are mechanically bonded to the copper tube to provide maximum heat transfer. A choice of fin spacings permits the selection of elements to meet your design requirements.
Why choose Modine’s fin tube radiation heaters?
Modine’s fin tube radiation heaters can be supplied in two- to eight-foot lengths and in a variety of colors to match most décor. A full complement of accessories to match enclosure styles provides flexibility in design and installation. Modine’s fin tube radiation heaters comply with the Buy American Act, as they are all made in the USA.
What is the heating effect factor for finned-tube baseboards?
Have a look at the rating tables for most finned-tube baseboard sold in North America and chances are you’ll see a footnote under the table that reads something like this: “Ratings are based on active fin length and include 15% heating effect factor.” So what exactly is meant by “heating effect factor?”
