Description
The utility model relates to the particularly free-standing automotive fan heater of warm-air drier.
Warm-air drier is the heat power supply device that heating such as automobile are used, and free-standing warm-air drier is to have the warm-air drier of confessing fuel system.Be mainly used in and supply warming, wind screen defrosting in automobile cab and the compartment.Not only be used for motorbus, touring car etc., also can supply heating such as sentry box, tent, warehouse to use.
Warm-air drier is made up of host part, heat exchanger component and accessory, host part comprises motor bracing frame (1), big fan (2), oil pump (3), motor (4) and combustion-supporting fan (15), and its effect is air-supply, send oil and send electricity that motor (4) is rotated as power.Air-supply is a heat supply exchange usefulness, and big fan (2) is sent into cold wind in the heat exchanger, makes it become hot blast and uses for heating.Combustion-supporting fan will be sent into combustion chamber (17) internal combustion of heat exchanger from the air that blast pipe (12) comes, and oil pump (3) will suck in the fuel from fuel tank, uses for combustion chamber (17) internal combustion.Heat exchanger component comprises the stratiform tubular that is welded into by heat resisting steel, interior combuster (17), secondary combustion chamber (10), circular passage (16), wind path inner ring (26), wind path outer ring (27), flue (9), smoke exhaust pipe (14) etc., its effect is heat exchange.Accessory comprises electric system, shell, frame, fuel tank etc.
Warm-air drier model of the prior art is a lot, but its volume is big, structure is compact inadequately, deficiency in draught, and the thermal efficiency is low, and fuel consumption is high, therefore, also has many places to be improved.
The purpose of this utility model is: a kind of improved free-standing warm-air drier is provided, and particularly free-standing automotive fan heater, this warm-air drier air quantity is big, and the temperature difference is low, thermal efficiency height, volume is little and compact conformation is reasonable.
The utility model warm-air drier has taked following measures to achieve the above object: the smoke evacuation portion (23) that reasonably designs heat exchanger (22), motor bracing frame (1) is located in the smoke evacuation portion (23) of heat exchanger (22) front end and is besieged, and the length of heat exchanger (22) accounts for 80% of the design's warm-air drier total length; On secondary combustion chamber (10), be provided with two with cross section vertical line symmetry, mutual angle be 110 ° flue (9); Big fan (2) adopts tube-axial fan; Oil pump (3) is located at big fan (2) afterwards.
Accompanying drawing in conjunction with the embodiments is elaborated to the utility model warm-air drier now:
Accompanying drawing 1 is the front view of the design's warm-air drier, and accompanying drawing 2 is that host part is installed in the schematic diagram in the heat exchanger, and accompanying drawing 3 is heat exchanger flue (9) and support fixation end (24) schematic diagram.
In order to improve the thermal efficiency of warm-air drier, must improve the design of prior art heat exchanger.The big more then heat exchanger effectiveness of heat exchanger area is high more.Desire strengthens heat exchange area, the length of the heat exchanger that just must extend, but the length of simple lengthening heat exchanger will cause the warm-air drier volume to increase.Warm-air drier in the prior art, its heat exchanger length is shorter, so its thermal efficiency is low.Through studying intensively of the design people, propose a lengthening heat exchanger length and don't increase the scheme of full captain's degree, be about in the smoke evacuation portion (23) of motor bracing frame (1) design in heat exchanger of host part, and it is besieged, this just makes the heat exchanger lengthening, makes its length reach 80% of full captain's degree, simultaneously, the design's warm-air drier total length is 580 millimeters only, has reached to make the requirement that the warm-air drier volume is little, compact to design and efficient is high (seeing attached Fig. 1 and 2).
Another characteristics of the design's warm-air drier are only to be provided with two flues (9), and vertical line and mutual angle that they are symmetrical in the cross section are 110 ° (seeing accompanying drawing 3).In the prior art, not only two of set flues, the position is also unreasonable, is difficult to improve the warm-air drier thermal efficiency.The position of the design's flue (9) is in the top of secondary combustion chamber (10) two sides, angle between two flues is 110 °, can make that cigarette is oblique to be discharged in the circular passage (16) up, combustion back along the circular passage (16) forwards bottom smoke exhaust pipe (14) advance, discharge from smoke exhaust pipe (14), the stream of cigarette is an arc, covers wind path inner ring (26) and wind path outer ring (27) comprehensively, thereby make cigarette be suitable for discharge, and carry out heat exchange with cold wind equably.In addition, the hot device length of the design strengthens, thereby rate of heat exchange is improved.
The used big fan of the design's warm-air drier (2) is an axial-flow type, and air quantity is big, and maximum air output can reach 750 meters
3/ hour, thereby improved caloric value and heat exchanger effectiveness.
The oil pump of the design's warm-air drier (3) is located at anterior big fan (2) afterwards.Long-pending in order to alleviate full body in the prior art, often oil pump is located at the outside, but the power source that this peripheral hardware oil pump need add, and actions such as action and motor (4) and big fan (2) are inharmonious sometimes, the design is located at anterior big fan (2) afterwards with oil pump, volume does not increase, compact conformation.
The working condition of the design's warm-air drier following (seeing accompanying drawing 1): after the energising, motor (4) drives big fan (2), oil pump (3), get rid of oil bowl (6) and combustion-supporting fan (15) rotates together.Oil pump (3) filters oil filter from the fuel oil of fuel tank suction, and through magnetic valve, flowline (5) is sent into get rid of oily bowl (6) in the combustion chamber (17), gets rid of to nebulize, and mixes mutually with the air of combustion-supporting fan (15) supply, is lighted by glow plug (7).After this, fuel oil constantly enters combustion chamber (17) for burning, and secondary combustion chamber (10), flue (9) and the annular channel (16) of the gas after the burning in heat exchanger (22) discharged from smoke exhaust pipe (14).The used axial-flow type big fan of the design (2) makes wind path inner ring (26) and wind path outer ring (27) of a large amount of air by heat exchanger (22) under high-speed motion, form warm braw, the due heating effect of warm-air drier that Here it is at air outlet.
The design's blower structure compactness, volume are little, in light weight, the thermal efficiency can reach 80%, caloric value can reach 45000 kJ (kilojoule)s/hour, air output reaches 750 meters3/ hour, fuel consumption is lower, is 1.5 l/hs to the maximum, and maximum power consumption is 120 watts, and fast, slow second gear is arranged, and can automatically control, and overtemperature protection is arranged, and running is reliable, and is easy to operate.
