Description
Affiliated technical field
The utility model relates to a kind of automobile-used hot air heating, defrosting fuel heater, belongs to automobile-used heating equipment technical field.
Background technology
Fuel heater has been widely used in various conveying mechanicals such as automobile, boats and ships heating, defrost etc. under low temperature environment as a kind of independently heating plant.And the heating of hot air heating fuel heater rapidly, and safety can also be used for purposes such as open-air tent heating, disinfection.Serious day by day along with the in short supply day by day and atmosphere pollution of fossil fuel further improved the thermal efficiency of fuel heater, and reducing blowdown all has important meaning to economic benefit and social benefit.
In existing hot air heating fuel heater, burning gases are turned back by the burner afterbody, and the toroidal cavity that flow through burner and heat exchanger form is discharged from exhaust outlet.Burner and heat exchanger cavity inside are provided with the fin of projection.Because burning gases are always with short as far as possible distance, discharge by the cavity that forms between burner and the heat exchanger, thereby make the holdup time in toroidal cavity of burning gases in this structure short, and the heat exchanger inner surface is subjected to uneven heating, so the heat exchange efficiency of heater is lower.The heater that has then takes to be provided with the method for dividing plate in toroidal cavity, make burning gases in the toroidal cavity of burner and heat exchanger formation, repeatedly change flow direction, be tending towards evenly improving the heat exchange efficiency of heater to improve the holdup time of combustion gas in toroidal cavity and heat exchanger is heated.But this method is made difficulty, weak effect, and the cost height.
Summary of the invention
The utility model is at the deficiency that existing hot air heating fuel heater exists, and a kind of simple in structure, volume is little, the thermal efficiency is higher, blowdown is lower small-sized hot air heating fuel heater is provided.
Small-sized hot air heating fuel heater of the present utility model adopts following technical solution:
This small-sized hot air heating fuel heater comprises burner, heat exchanger, intermediate, combustion-supporting fan, heat supply fan, fan electromotor, heat insulation spacer and inlet chamber cover plate, burner is installed in the inner chamber of heat exchanger, form toroidal cavity between the two, the heat exchanger front end face is connected with intermediate; The intermediate front end is fixed with fan electromotor, and the rear end armature spindle of fan electromotor is equipped with combustion-supporting fan, and the front end armature spindle is equipped with the heat supply fan; The combustion air volume control valve is equipped with at the intermediate top, the intermediate front end face is equipped with the inlet chamber cover plate, annular groove on this cover plate and the intermediate forms inlet chamber, heat insulation spacer is fixed on the heat exchanger outer wall fin, on the heat insulation spacer case is installed, the front end of case is equipped with front shroud, and the rear end is equipped with hood; The inwall of heat exchanger is provided with and circumferentially uniform fin of pitch such as is, and becomes big by the bottom gradually along the make progress spacing of fin of both sides internal face.
Heat exchanger is made up of anterior cylindrical section and afterbody conical section, and the cylindrical section inwall is provided with and circumferentially uniform fin of pitch such as is, and non-equidistance between each fin becomes big by the cylindrical section bottom gradually along the both sides internal face spacing that makes progress.Equally, inter fin space on the afterbody conical section inwall also upwards becomes big by the bottom along the both sides internal face gradually, the variation of spacing can be continuous between the fin, also can be stepped change, and this variation is that the variation by fin self thickness realizes.This kind design, because the bottom inter fin space is little, the fuel gas flow resistance is big, but the spacing of top fin is big, thereby force attempt short circuit high-temperature fuel gas as far as possible equably by way of in, the fin back of conducting heat in top discharges, heat exchanger is heated be tending towards even to improve the holdup time of combustion gas in toroidal cavity; In addition by way of the combustion gas of bottom fin, also can be because of the fin thickness of short circuit place passage is big, thermal resistance is little and with heat transferred heat exchanger as much as possible, thereby reduces the heat that exhaust is taken away, and improves the complete machine heat exchange efficiency.
The heat exchanger bottom is provided with the fuel pipe locating aperture.The metal fuel pipe of burner can utilize this positioning port spacing, to avoid metal fuel pipe stress deformation when plugging oil hose.
Heat insulation spacer is provided with two parallel raised ribs that distribute along circumferentially.The cross sectional shape of raised ribs can be one of semicircle, triangle, trapezoidal and rectangle.Article two, formed an air ring between the raised ribs, this air ring has heat-blocking action, can reduce the heat dissipation capacity of fin through case, thereby reduces heat loss.
The combustion air volume control valve that install at the intermediate top is under the certain situation of burner fuel delivery, and the size by this valve opens and closes can make the burner air-fuel ratio be in optimum state, to reach sufficient combustion, reduces the purpose of blowdown.
Characteristics of the present utility model are simple in structure, and volume is little, easy accessibility, thermal efficiency height.The complete machine thermal efficiency can improve more than 8%, and blowdown can reduce more than 6%.
