As the technical scheme that can replace, Programmable Logic Controller can start auxiliary heating equipment automatically by measuring the heat exchange amount of heat exchanger 13.If the heat exchange amount of heat exchanger 13, lower than certain numerical value, starts automatically.The heat exchange amount of heat exchanger can obtain by calorimeter 17.
As one preferably, auxiliary heating equipment is electric heating equipment.
As another, have choosing, auxiliary heating equipment is boiler.
Certainly, the present invention also provides a kind of radiator, and this kind of radiator can be used as an independent radiator product and protect.
Described hot user's radiator is finned tubular radiator, comprise upper header 20, lower collector pipe 23 and be connected upper header 20 and the finned tube 22 of lower collector pipe 23, described finned tube 22 comprises circular base tube 24 and the first fin 25, the second fin 28, the extended line that the first fin 25 and the second fin 28 are arranged on outside and the first fin 25 and second fin 28 of base tube 24 intersects at the central axis of base tube at the place, the center of circle of base tube 26, and the first fin 25 and the second fin 28 are symmetrical along the first plane B mirror image by base tube central axis; Described finned tube comprises the 3rd fin 30 and the 4th fin 29, described the 3rd fin 30, the 4th fin 29 are symmetrical with the first fin 25 and the second fin 28 mirror images respectively along the second plane C, and described the second plane C is vertical with the first plane B and pass through the central axis of base tube 24; Between described the first fin 25 and the second fin 28, the first brace 27 is set, it is circular arc type metallic plate that the second brace 31, the first braces 27 and the second brace 31 are set between described the 3rd fin 30 and the 4th fin 33; The central axes of the central axis of described circular arc-shaped metal plate and base tube 24; Described base tube is straight tube, and the central axis of described adjacent base tube is parallel to each other.
As one preferably, described heat exchanger 13 is heat-exchangers of the plate type.
As one preferably, as shown in Figure 5,6, the first fin of described radiator and the fin height of the second fin diminish to top gradually from the bottom of user's radiator.By such setting, can be so that in the flow process of air in the space of fin, gap 26 areas are more and more less, thereby make its flow velocity more and more faster, and chimney effect is more and more obvious, thereby strengthens heat exchange.
As one preferably, the amplitude that the first fin of described radiator and the fin height of the second fin diminish to top gradually from the bottom of user's radiator is more and more lower.Experiment showed, in radiator, by such setting, it is constant or become gradually large situation that heat transfer effect will obviously be better than the amplitude that changes.
As one preferably, the first fin of described radiator and the fin height of the second fin are parabolic structure to top from the bottom of user's radiator.This set is that fairshaped effect has been played in the variation of fin, reaches best heat transfer effect, because bottom extension goes out a part, makes more air enter gap simultaneously.
Two kinds of situations for Fig. 5 and Fig. 6, it is A that the fin of radiator still can adopt the angle between described the first fin and the second fin, the length of the first fin and the second fin is L, the outer radius of base tube is R, the satisfied formula of fin height H on axial along base tube, but consideration ease of processing, can finned tube be divided into several parts in short transverse, every part is taked average fin height H, but length L remains unchanged, adopt the mode of total length, by average fin height, determine included angle A.
Can certainly be directly by adopting average fin height, calculate an angle, along the height angle of fin, remain unchanged.
Certainly, in particular cases, because the difficulty of manufacturing, fin also not necessarily leaves no choice but meet the optimization formula of above-mentioned several parameters, also can be set to be convenient to the mode of manufacture, for example as shown in Figure 6, fin is the mode of straight line, remain unchanged, but circular arc closure plate is apart from the distance in the center of circle of finned tube base tube, along the height of base tube, constantly reduces highly always.
As preferably, circular arc closure plate is apart from the distance in the center of circle of finned tube base tube, and the streamlined variation along being parabolic in short transverse because bottom extension goes out a part, makes more air enter gap simultaneously
