A cold air inlet and a hot air outlet are arranged on two sides of the heat exchanging area respectively. A centrifugal fan is mounted on one side of the hot air outlet. A plurality of heat-pipe heat exchangers are arranged between the combustion area and the heat exchanging area. The heat-pipe gas hot-air stove applied to the drying room is simple in structure and ingenious in design, and superconduction heat transfer is achieved by the evaporation of liquid working media inside the gas hot-air stove and the phase change of condensation. The heat-pipe gas hot-air stove applied to the drying room has the advantages that heat transfer coefficient is high, temperature distribution is even, thermal response speed is high, structure is compact, energy is saved, and the like.
Description
Technical field
The utility model relates to a kind of heat pipe-type fuel gas hot-blast stove that is applied to baking room.
Background technology
In painting operation, the oven dry energy consumption is high, and no mode of heating, environmental pollution are also different.Select suitable hot-blast stove to guaranteeing workpiece surface quality, improve the workpiece antiseptic property, reduce production costs, energy savings plays important effect.The oven dry most common form has electrical heating, Steam Heating, coal-fired heating, fuel Heating, combustion gas heating etc. at present.And consider composite factors such as energy consumption, fire-fighting, environmental protection, and the natural gas heating is best mode of heating, it has cleaning, environmental protection, characteristics that cost is low.And the heat exchanger combustion gas is the key component of hot-blast stove, and traditional tubular heat exchanger heat exchange efficiency is low, causes energy waste.
At present, what the combustion heater heat exchanger adopted is traditional tubular heat exchanger, and flue gas and air flow to realize the process of flue gas and air heat exchange outside pipe with in the pipe respectively; Reach the effect of heat exchange; But this heat exchange mode, energy utilization rate is low, causes energy waste.
The utility model content
The purpose of the utility model is to provide a kind of heat pipe-type fuel gas hot-blast stove that is applied to baking room; Realize the superconduction heat transfer of conducting heat through the phase transformation that relies on evaporation of self internal liquid working medium and condensation; Overcome the deficiency in the conventional art, thereby realized the purpose of the utility model.
The technical problem that the utility model solved can adopt following technical scheme to realize:
Be applied to the heat pipe-type fuel gas hot-blast stove of baking room, comprise heated oven chamber's body, said heated oven chamber body is divided into combustion zone and heat transfer zone; One side of combustion zone is equipped with burner; The opposite side of combustion zone is provided with outlet flue, and the both sides of heat transfer zone are separately installed with cold wind air inlet and hot blast air outlet, in a side of hot blast air outlet centrifugal fan is installed also; It is characterized in that, between said combustion zone and heat transfer zone, be provided with some heat exchange of heat pipes.
In an embodiment of the utility model, said heat exchange of heat pipe comprises evaporator section, condensation segment and is positioned at adiabatic section between the two, and said evaporator section is arranged in the combustion zone, and condensation segment is arranged in the heat transfer zone.

The beneficial effect of the utility model is: simple in structure; Design ingenious; Rely on the phase transformation of evaporation of self internal liquid working medium and condensation to realize that the superconduction of conducting heat, have advantages such as heat transfer coefficient height, uniformity of temperature profile, thermal response are rapid, compact conformation, energy savings.
Description of drawings
Fig. 1 is the structural representation of the described heat pipe-type fuel gas hot-blast stove of the utility model.
Fig. 2 is the structural representation of the described heat exchange of heat pipe of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with the specific embodiment, further set forth the utility model.
As shown in Figure 1; The described heat pipe-type fuel gas hot-blast stove of the utility model comprises heated oven chamber's body, and said heated oven chamber body is divided into combustion zone 100 and heat transfer zone 200; One side of combustion zone is equipped with burner 110; The opposite side of combustion zone is provided with outlet flue 120, and the both sides of heat transfer zone are separately installed with cold wind air inlet 210 and hot blast air outlet 220, in a side of hot blast air outlet centrifugal fan is installed also; It is characterized in that, between said combustion zone and heat transfer zone, be provided with some heat exchange of heat pipes 300.
As shown in Figure 2, said heat exchange of heat pipe is made up of shell, wick, hydraulic fluid, and the outer surface of said heat exchange of heat pipe is provided with wick 340, and the arranged outside of wick has some fins 350.Be pumped into 1.3 in the shell * (fill with an amount of hydraulic fluid after the negative pressure of the Pa of 10-1～10-4), make to seal after being full of liquid in the wick capillary porous material of being close to inwall.One end of pipe is an evaporator section 310, and the other end is a condensation segment 330, and the centre is adiabatic section 320.When the heat pipe two ends produced the temperature difference, the liquid of evaporation ends will be vaporized rapidly.Because vaporization back steam pressure is bigger, under action of pressure, the steam of generation arrives condensation end, and the liquefaction release heat is to realize being delivered to condensation end to heat from evaporation ends.Utilize the high-speed of phase transformation reaction between liquid state and the gaseous state, the heat conduction efficiency of heat pipe is than high hundreds of times of common fine copper, even thousands of times.Liquid through capillarity, flows back to evaporation ends after condensation end condenses liquefaction.So move in circles, constantly heat is delivered to the low end of temperature.
The workflow of the utility model is following: at first be admitted to burner through filtering post-decompression natural gas, the air of sending into the burner pressure fan is blended in the burner hearth internal combustion; The heat that produces will be vaporized the liquid of heat pipe evaporation ends rapidly.Because vaporization back steam pressure is bigger, under action of pressure, the steam of generation arrives condensation end, runs into the cold air that air inlet is come in, and the fast liquefying release heat is to realize being delivered to condensation end to heat from evaporation ends.Utilize the high-speed of phase transformation reaction between liquid state and the gaseous state, the heat conduction efficiency of heat pipe is than high hundreds of times of common fine copper, even thousands of times.Liquid through capillarity, flows back to evaporation ends after condensation end condenses liquefaction.So move in circles, constantly heat is delivered to the low end of temperature.The cold air that absorbs heat reaches design temperature, is seen off by air outlet through blower fan.Simultaneously, the waste gas of burning generation is discharged by outlet flue.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
