Description
Technical field
The present invention relates to heating and ventilation project technical field, especially a kind of novel high efficiency plate low temp heating piece and its dedicated
Component.
Background technique
The supply water temperature of current natural convection radiator is all higher, and radiator surface heat dissipation area is smaller, once for
Coolant-temperature gage reduces, and is just unable to satisfy the requirement of heating load.In addition to supply water temperature and the poor, flow of heating temperature etc. are by terms of heat source
Factor outside, restrict radiator heat exchange principal element be pipe external cooling and pipe internal heat transfer, so-called pipe external cooling i.e. manage
Outer surface includes the heat exchange between fin surface and air, and heat exchange amount depends on heat exchanger surface product size, fin efficiency, surface
With the temperature difference of air, the unimpeded of air current composition, air fluidised form (laminar flow or turbulent flow), the destruction in boundary layer and recombination etc., this
A little factors interact mostly, complicated and changeable；Water flowing heat transfer in so-called pipe internal heat transfer, that is, radiator pipe, heat output
The factors such as strengthen depending on the fluidised form in pipe, the temperature difference, interior surface area, the coefficient of heat transfer caused by surface characteristic.And radiator
Overall heat exchange characteristic depends on above-mentioned all factors, especially pipe external cooling and the Proper Match of pipe internal heat transfer and puts down
Weighing apparatus.For traditional radiator since manufacturing process and design of heat transfer are unreasonable, typically inner flow tube diameter is big, and external specific surface is wanted
