Abstract

The utility model relates to a domestic thermotube-type gas air-heater, which is mainly composed of a burner, a heat tube bundle, a centrifugal fan, etc. The heat generated from the burner is transferred from an evaporating section to a condensing section by the heat tube bundle to change the cold air to hot air, and the hot air is sent to every room through the hot air transferring tube by the centrifugal fan to heat. The utility model has the advantages of simple structure, low manufacturing and use cost and high thermal efficiency, and one air heater can heat a plurality of rooms, which is especially suitable for families with gas or liquefied gas.

Description

Domestic thermotube-type gas air-heater

The utility model belongs to the heat pipe-type steam air heater to the room release hot-air that will heat that a kind of family uses.

At present, the household warming kind that is used for warming is a lot, make heating source with electricity mostly, as quartzy electric heating device etc., though it is easy to use, but energy consumption is big, result of use is unsatisfactory, the electric heating device of a power consumption 800W is difficult to make room temperature obviously to improve, and result of use preferably the water-heating system family that is difficult to spread to dispersion because of complex structure use, in order to be fit to family's warming, also utilize combustion gas earlier water to be heated, with the radiator of delivery in the Heating Room, utilize cross-ventilation that near the air heat the radiator is reached the heating purpose again, also there is complex structure in this warmer of hot water circuit that utilizes, the cost height, the shortcoming that the thermal efficiency is lower for the also fouling easily of untreated water, further reduces the thermal efficiency.

The purpose of this utility model is in order to overcome above-mentioned weak point of the prior art, to utilize combustion gas to make heating source, designs a kind of simple in structurely, and thermal efficiency height can directly provide the family expenses heat pipe-type combustion gas steam air heater of hot-air.

The utility model mainly is to use the high heat pipe bundle of heat conduction efficiency that heat is passed to condensation segment from bringing-up section, with centrifugal blower the hot-air of condensation segment is delivered to the room that needs heating by hot blast conveying pipe again.Its structure is by housing, burner, the heat pipe bundle, reducing air channel joint, centrifugal blower and union elbow are formed, its installation site and annexation are: housing is separated into combustion chamber and air chamber with dividing plate, burner is contained in the bottom of combustion chamber, the air inlet pipe of burner is connected with coal gas or liquefied gas, one section top that is contained in the combustion chamber of heat pipe bundle, another section of heat pipe bundle is contained in the top of air chamber, reducing air channel joint is contained in the middle part of air chamber and is connected with the centrifugal blower air inlet that is contained in the air chamber bottom, centrifugal blower air outlet be connected with hot blast conveying pipe again after union elbow is connected, hot-air can be delivered to each room heating by hot blast conveying pipe.In order further to improve heat transfer efficiency, the heat pipe bundle is made up of some metal tubes and some fins, and metal tube is distributed in the different parts of fin and closely contacts with fin, and metal tube inside is pumped into vacuum and imbibition core and working medium are housed.

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is structural representations of the utility model heat pipe bundle.

Be further described as follows in conjunction with the accompanying drawings:

Referring to accompanying drawing 1, housing 1 is separated into combustion chamber and two parts of air chamber by dividing plate 4, burner 2 can change the main gas valve on the general burner in the gas heater into the electromagnetic type structure by the hydraulic type structure and can use, the motor parallel connection of its solenoid and centrifugal blower after power switch be connected with the 220V power supply, burner 2 is contained in the bottom of combustion chamber, the air inlet pipe 3 of burner 2 is connected with coal gas or liquefaction tracheae, heat pipe bundle 8 is contained in housing top, one section of getting one's things ready in the combustion chamber of heat pipe is evaporator section, one section that is contained in the air chamber is condensation segment, reducing air channel joint 5 is housed below heat pipe bundle condensation segment to be connected with the air inlet of centrifugal blower 6, the air outlet of centrifugal blower 6 connects union elbow 7, stretches out housing from the air chamber bottom and is connected with hot blast conveying pipe.Referring to accompanying drawing 2, the heat pipe bundle is made up of some metal tubes 9 and some fins 10, and the inside of metal tube 9 is pumped into vacuum and imbibition core 11 is housed and working medium 12.During use, put the kindling material of burner 2 earlier, connect the power supply of centrifugal blower and solenoid again, make blower fan rotate and open main gas valve, because of the kindling material of burner is lighted earlier, main gas valve is opened the afterburner nozzle and is promptly lighted to heat pipe Shu Jiare, working medium in the evaporator section is become steam and is flowed to condensation segment by liquid, steam becomes liquid again after condensation segment is with heat transferred metal tube and fin, because of the capillary force of imbibition core in the metal tube makes the liquid of condensation segment constantly flow to evaporator section, and the steam of evaporator section constantly flows to condensation segment, so move in circles, and cold air is heated into hot-air can be delivered to the needs heating again through centrifugal blower room by the condensation segment of heat pipe bundle.

It is heat transfer element that the utility model adopts the heat pipe bundle, thermal efficiency height uses coal gas or liquefied gas to be the energy, and hot-wind heating is more more comfortable than the infrared heating that quartz ampoule sends, and save a large amount of electric energy, compare with the hot water circulation type heating system, cancelled water circulating pump and aqueduct and interior radiator, have simple in structure, the advantage that cost is low, and bigger use flexibility is arranged, and a steam air heater can be for the heating of several rooms, and the family that is particularly suitable for coal gas or liquefied gas uses.

Claims (2)

1, a kind of family expenses heat pipe-type combustion gas steam air heater comprises housing and burner, it is characterized in that housing is separated into combustion chamber and air chamber with dividing plate, burner is contained in the bottom of combustion chamber, the evaporator section of heat pipe bundle is equipped with on the top of combustion chamber, the condensation segment of heat pipe bundle is contained in the top of air chamber by dividing plate, the middle part of air chamber is equipped with reducing air channel joint and is connected with the centrifugal blower air inlet that is contained in the air chamber bottom, and the air outlet of centrifugal blower is connected with hot blast conveying pipe by union elbow.

2, family expenses heat pipe-type combustion gas steam air heater as claimed in claim 1 is characterized in that the some fins that the heat pipe bundle is equipped with imbibition core and working medium and evacuated metal tube by some inside and tightly is enclosed within the metal tube outer wall form.
