Description
Technical field
The present invention relates to a kind of heating heated kang, belong to the building and heating equipment technical field.
Background technology
Northern China cold and severe cold area life in the countryside are cooking and heating with the major part of energy, and wherein heating energy consumption occupies significant proportion.The traditional heating system in rural area comprises heated kang, wall with flues, stove and native heating installation etc., and heated kang still is widely used so far as the most ancient heating system of China.According to the statistics of Liaoning Province's rural energy office, by the end of the year 2004, the whole nation has 6,685 ten thousand to make the bed approximately, population in use reach 1.75 hundred million (Zhuan Zhi. the flow of flue gas of Chinese a heatable brick bed and Study on Heat Transfer, Dalian University of Technology's doctorate paper, in June, 2009, P2.).Use heated kang to heat under construction and not only can realize utilizing biomass energy to improve indoor thermal environment, and can realize reducing the target that commercial energy consumes.
But,, cause traditional heated kang aspect thermal characteristics, to remain in a lot of weak points because the design of heated kang lacks the theoretical foundation support mainly based on experience among the people at present.According to investigations, tradition is landed the thermal efficiency of a heatable brick bed a heatable brick bed body and is approximately 14～18%, and the thermal efficiency of kitchen range also has only about 8～10%, and kang-linked kitchen stove integrated heat efficiency less than 45% (Guo Jiye. northern firewood-saving and coal-saving kang-linked kitchen stove technology lecture (two), rural energy, 1998 (6): 12-14.).Traditional in recent years heated kang have be used gradually commodity can heating system such as the trend that substitutes such as native heating installation, domestic boiler, air-conditioning, go down for a long time and will increase the weight of the fuel in China's rural areas supply pressure.
In addition, there is the contradictory problems that satisfies simultaneously between room heating load demand and a heatable brick bed surface heat comfortableness target in actual applications in tradition heated kang, when indoor will reach than higher thermal comfort the time, just need the more fuel of kitchen range internal combustion, finally certainly will cause a heatable brick bed plate surface temperature higher, cause that the part is too hot, dry, phenomenon such as get angry.
For these reasons, and characteristics such as the Regional Distribution of considering a heatable brick bed is wide, number of applications is many, the energy-saving and emission-reduction potentiality are big, being necessary to take reasonable manner that traditional heated kang is rationalized transforms and Organic Renewal, when realizing improving heated kang, can also effectively improve the thermal comfort on a heatable brick bed surface to the indoor heating ability.
Summary of the invention
The purpose of this invention is to provide a kind of convection type heating heated kang,, effectively improve utilization efficiency of energy and delivery efficiency by reclaiming the cooking stove flue gas heat and carrying out indoor heating in the Convective Heating mode.
Technical solution of the present invention is as follows:
A kind of convection type heating heated kang, contain kang panel, outer a heatable brick bed body, the exhanst gas outlet of kitchen range and the exhanst gas outlet of a heatable brick bed, it is characterized in that: a heatable brick bed body in outside described, being provided with in a heatable brick bed body, a heatable brick bed body is the rectangular barrel structure of both ends open in this, and is equipped with fin in the rectangular tube outside and inner surface; One end of described rectangular tube links to each other with the exhanst gas outlet of kitchen range, and the other end links to each other with the exhanst gas outlet of a heatable brick bed; The air flow channel that formation seals between a heatable brick bed body and the outer a heatable brick bed body in described is provided with blower fan at an end of the air flow channel that is positioned at a heatable brick bed body bottom, and the other end of the air flow channel of a heatable brick bed body side surface is provided with air outlet outside being positioned at.
The plane parallel at the placement direction of the fin that is positioned at the external side of a heatable brick bed of the present invention and rectangular tube opening place is positioned at the rectangular barrel that the placement direction of the fin of a heatable brick bed body inboard contacted with it and the plane at rectangular opening place and guarantees vertical simultaneously; Smoke barrier is equipped with in a heatable brick bed body bottom surface inboard in described, and smoke barrier adopts splayed to arrange; Described outer a heatable brick bed body and the contacted place of wall are covered with insulation material.
The present invention has the following advantages and the high-lighting effect:
The present invention is mainly used in northern China cold district and severe cold area villages and small towns building heating.This heated kang is by increasing interior a heatable brick bed body for providing heat exchanger between hot flue gas and the air, thereby strengthen the whole heat capacity of heated kang, effectively solve the problem of common heated kang heating room air scarce capacity, make heated kang when satisfying the sleep comfortableness, can also satisfy the comfortableness requirement of whole day indoor thermal environment in winter.This kind convection type heating heated kang has the modularization mounting points, can be according to free selection schemes such as room-sized, layout, heating requirements, both can select common bavin kitchen range as thermal source, can select coal stove, biomass stove etc. as thermal source again, not only can realize round-the-clock continuous heating, and improved efficiency of energy utilization, have good development potentiality.
