CN2296505Y - High efficiency household heating box - Google Patents

Abstract

The utility model relates to a high efficiency household heating box, which is characterized in that a box type heat exchanger is added to an outlet of a coal stove, and the inner part of a box body is composed of a plurality of cooling plates made of rectangular metal thin plates and a rectangular fume gas passage B. The box body is composed of three parts of a front box cover 1, a heat exchanger 2, and a rare box cover 3, the front box cover is connected with a fume gas outlet of the coal stove, the rear box cover is connected with a fume cylinder for exhausting fume, and air in the heat exchanger moves upwards because of heating. Heat can be spread into the inner part of the house so that heat efficiency is high and the goal of energy-saving can be achieved.

Description

A kind of efficient domestic heating case of utility model

The utility model relates to a kind of equipment of domestic heating, particularly a kind of case body equipment of domestic heating efficiently.

The small town citizen warming mainly relies on coal stove in rural area and the major part at present.It is coal stove and chimney that coal stove for heating is divided into two parts.The full natural radiation by stove outer covering and chimney that distributes of heat is finished, and its efficient is very low, and most of heat has little time to distribute in doors and just taken out of outdoorly by flue gas, has wasted the energy.

The purpose of this utility model is that the high domestic heating case body equipment of a kind of thermal efficiency of design can be used the heat of flue gas by this case body equipment as far as possible fully, thereby reaches purpose energy-conservation and the raising thermal efficiency.

Structure of the present utility model and embodiment are illustrated referring to accompanying drawing 1 and accompanying drawing 2:

This heat exchange box house is made of the sheet metal 8 and the rectangle exhaust gases passes B of several rectangles, and casing has preceding case lid 1, and heat exchanger 2 and back box lid 3 three parts are formed, and the form with flange face between three parts connects with screw 4,5 or slot.Before case lid be connected with the exhanst gas outlet of coal stove is supporting, back box lid is connected with the smoke evacuation chimney, and is outdoor by the flue gas discharge after the abundant heat exchange of hot flue gas quilt in this heating case of discharging from burner hearth.The heat overwhelming majority of flue gas is converted into room air heat energy in this heating case, all the other small part heats distribute in chimney, and outdoor exhaust gas temperature is lower, and is favourable to the protection environment.The structure of heat exchanger 2 is that exhaust gases passes is the level trend along vertical square type passage for the binary channels type, and air is trend up and down, and two kinds of fluids are by several metallic walls 8 and several rectangular channels B heat exchange.

Operation principle is as follows: the flue gas inlet A level of entering of case lid 1 in the past moves towards heat exchange rectangular channel B, and the outlet flue D from back box lid 3 discharges again.And air passes from the channel C of the trend up and down of heat exchanger from bottom to top.Air is heated intensification in the lower channel on heat exchanger 2 after, its volumetric expansion and density reduce, automatically after formation ascending air (the heat power effect of gaseous fluid) hot-air upwards flows out, cold air replenishes immediately from the bottom and enters heat exchanger channels, go on so continuously, just form the benign cycle of nature fluid interchange, under the constant situation of Coal-fired capacity, increase substantially indoor temperature, reach the energy-conservation purpose of heating again.

Effect of the present utility model is: adopt the box-type heat exchange structure to overcome original heating equipment heat radiation Inefficient shortcoming, the heat transfer area of hot flue gas and room air is big, has utilized the heat power of air fluid Effect makes air automatically form directed flow in heating box, thereby has greatly improved heat exchange efficiency. Casing The formula structure also can reach the purpose of directed providing warm air, i.e. upper and lower surface air gateway and the finger of heat exchanger 2 Fixed zone is equipped with distinguished and admirable pipeline 6,7, can automatically form circulation, and major advantage is sanitation and hygiene between heating.

Metals such as material of the present invention is optional cylinder iron, galvanized iron sheet, aluminium, copper, steel.Can be made into the different space environment of adaptation of different shape and specification.

Claims (3)

1, a kind of efficient domestic heating case, it is characterized in that adding a box heat exchanger in coal stove outlet is made of the sheet metal fin (8) and the rectangle exhaust gases passes (B) of several rectangles in the inside of cabinet shell, casing has preceding case lid (1) heat exchanger (2) and back box lid (3) three parts composition.

2, by the described efficient domestic heating case of claim 1, the structure that it is characterized in that described box heat exchanger is the binary channels type, be that exhaust gases passes is the level trend along vertical rectangular channel, and air duct for up and down the trend, two kinds of fluids are by a plurality of rectangle exhaust gases passes (B) and a plurality of layer of metal wall (8) fin heat exchange.

3, the material that it is characterized in that described heating case by the described efficient domestic heating case of claim 1 is cylinder iron optional, metals such as galvanized iron sheet, steel, copper, aluminium.
