Fig. 2 is the structural representation of heat(ing) coil.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of vertical warm braw unit, comprises the cabinet 1 with air inlet 3 and air outlet 4, is provided with blower fan 2 and heat(ing) coil 6 in cabinet 1.Heat(ing) coil 6 is in tilted layout in cabinet 1, and the angle of inclination in relative level face is 30 ~ 60 degree; The body spacing of heat(ing) coil 6 increases from low to high gradually, and it is 1.05 ~ 1.3 times that spacing increases progressively amplitude.
Warm braw unit due to the present embodiment is mainly used in industrial heating heating, is 800 ~ 1040m according to air quantity
3/ h, the angle of inclination arranging heat(ing) coil relative level face is 30 ~ 60 degree, to maintain the better heat exchange efficiency under this air quantity; And 45 degree of inclinations can be set further, realize maximum heat exchange efficiency.In addition, in air-flow uphill process, wind speed reduces gradually, in the bottom of heat(ing) coil, because wind speed is maximum, air-flow and body shorter for time of contact, and the top of heat(ing) coil, wind speed decreases, and heat-exchange time increases to some extent; Based on above-mentioned situation, the present embodiment is keep heat(ing) coil heat exchange everywhere even, with air-flow uniformity of temperature profile, setting dish tube pitch increases from low to high gradually, bottom heat-exchange time is short, but heat exchange area is large, and the heat exchange of top part time is long, but heat exchange area is relatively little, keep that there is in whole cabinet equal heat exchange position.According to the size of air quantity and the power of blower fan, the amplitude that spacing increased progressively is 1.05 ~ 1.3 times, and the air heat-exchange efficiency controlled in cabinet is in good state, and can to arrange the amplitude of increasing progressively further be 1.1 ~ 1.2, adapt to the size of air quantity, keep the equalized temperature of air-flow everywhere in cabinet.
The bottom of cabinet 1 and top are provided with air feed shutter window and air-out shutter, respectively corresponding air inlet and air outlet.Cabinet adopts the mode of bottom inflow and top air-out, and the air be heated expands and rises, and cold air sinks, and realizes cross-ventilation; In addition, adopt the mode of bottom in and top out, the flow resistance of air-flow can be reduced, reduce blower fan power consumption.Air feed shutter window and air-out shutter have waterproof in effect, avoid rainwater to enter in cabinet.Meanwhile, in air feed shutter window and air-out shutter, be provided with Air Filter, prevent dust from entering in cabinet, affect the service life of electrical heating coil pipe.
In another embodiment, heat(ing) coil 6 is divided into two sections of inclination, and the highest point of every section is positioned on the vertical axis of cabinet.For improving heat exchanging efficiency, heat(ing) coil is set to two sections of doubling, increases heat exchange area with this, and the highest point controlling every section is positioned on the axis of cabinet, realizes best heat transfer rate.
Vertical warm braw unit aluminium alloy profile does skeleton, and panel adopts color steel, inner panel galvanized steel plain sheet, central filler polyurethane foaming raw material, thickness 18mm.Be filled with polyurethane foam raw material in cabinet inwall, be equivalent to the thermal insulation layer in cabinet inwall, the thermal loss of heat(ing) coil can be reduced, improve capacity usage ratio.
Air outlet 4 place is provided with arc wind waveguide plate 5, and for guiding air-flow to discharge to air outlet, reduce the resistance of air-flow, what increase warm braw blows to distance, promotes heating effect.
In another embodiment, if there are two air outlets, two pieces of wind deflectors arranged dorsad are set between air outlet, to airflow diversion, and air-flow are led, to meet the needs that diverse location warm braw blows.
The foregoing is only better implementation example of the present invention, be not limited to the present invention, all within the present invention's spirit and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
