Description

A kind of heat collecting type kitchen range support

Technical field

This utility model relates to field of mechanical technique, is specifically related to a kind of heat collecting type kitchen range support.

Background technology

At present, the structure that the support used between household gas range and cooking utensils uses is surrounding and opens wide.Combustion gas is fired The high-temperature gas produced after burning, in addition to making cooking utensils to cooking utensils transmission heat and being heated, the portion also can opened wide to surrounding Position carries out the heat transfer (i.e. dispelling the heat) without effect to surrounding, therefore produced by fuel gas buring, heat-energy losses is big.As: one is subject to Hot cooking utensils are flat, and it is that H is high with the vertical height of fire cover for gas kitchen range top surface plane, and the flat of cooking utensils is heated A diameter of D, then the ratio of the area of dissipation that cooking utensils heating surface area is dispelled the heat to surrounding with hot gas is expression formula 1):

Assume: flat a diameter of 20 centimetres of cooking utensils, the flat vertical height with gas stove fire caping plane of cooking utensils It it is 5 centimetres, then its ratio isI.e. to the area of dissipation of surrounding as the heating surface area of cooking utensils big Little.Waste heat the most not aspect plus hot gas is recycled, and is directly arranged in air, and the waste heat loss of this part is also Greatly, so, effective utilization rate of thermal energy produced by household gas range fuel gas buring is the lowest.

Thermodynamics relevant knowledge is below used to do a brief introduction:

Heat is propagated to cryogenic object from high temp objects, and its circulation way has following three kinds:

1, conduction heat transfer, this kind of heat transfer type is divided into again steady heat conduction and unsteady heat conduction.Combustion gas because of household gas range Being substantially the flow under constant voltage, can be considered stable heat conduction, its formula is expression formula 2):

$Q=\frac{\mathrm{\λ}*F*(tw.1-tw.2)}{\mathrm{\σ}}---2),$

Wherein: Q is the heat of unit Time Transmission, λ is heat conductivity, and F is the area of planomural, tw.1 and tw.2 is flat Wall inner surface and the temperature of outer surface, σ is the wall thickness of heated object.

The thermal energy that heating object in cooking utensils is obtained, it is simply that realized by the conduction heat transfer of cooking utensils, The amount of heat conducted, is directly proportional to the internal-external temperature difference of cooking utensils, is directly proportional to the heat conductivity of cooking utensils, and cooks a meal The heating surface area of thing apparatus is directly proportional, and is inversely proportional to the wall thickness of cooking utensils.

2, the convection heat transfer' heat-transfer by convection of heat transfer, this kind of heat transfer type refers to that the heat being passed between solid wall or fluid by fluid passes Passing, and passed to the diabatic process of fluid about by solid wall, its formula is expression formula 3):

$Q={\∂}_{\mathrm{\κ}}*(t_f-t_w)*F---3),$

Wherein, Q is the heat of unit Time Transmission,For coefficient of heat convection, t_fAnd t_wIt it is the temperature between two objects It is poor to spend, heat exchange area when F is to contact with fluid.

When the fluid is flowing, on solid wall surface, there is one layer of fluid boundary layer doing Laminar Flow, in this layer, heat The transmission of amount is carried out in conduction heat transfer mode completely, it is seen then that convection heat transfer' heat-transfer by convection process is a sufficiently complex process, and it includes limit Conduction heat transfer in the outer convection heat transfer' heat-transfer by convection of interlayer and border.

3, radiant heat transfer, this kind of heat transfer is to carry out heat transmission in the form of an electromagnetic wave, the electromagnetic wave of these transmission radiation Can again be changed into heat energy after being absorbed by object, so being also called heat ray or claiming radiation energy, its formula is expression formula 4):

$E=C*{\left(\frac{T}{100}\right)}^4---4),$

Wherein: E is the radianting capacity of object, C is the radiation coefficient of object, and T is the absolute temperature of body surface.

Radiant heat transfer, the spoke of solid is all there is between gas and solid, between solid and solid and between gas and gas Penetrate spectrum and can absorb and radiate the radiant flux of all wave bands because being continuous print, the radiation spectrum of gas because of be discontinuous and Can only radiate and absorb the radiation energy in a certain standing wave segment limit, remainder will transmit through, thus, and the radiation of gas and suction Receipts have selectivity.

In sum, the heat of the heating surface of cooking utensils, come from the burning gases produced hot gas of burning to spreading Heat and heat radiation conduct heat, and then the conduction heat transfer of dependence cooking utensils heated walls is given the heat absorbed again needs the article of heating The loss of energy (this process have).And existing kitchen range to be all surrounding open wide, therefore, thermal loss is the most serious.

Therefore, it is badly in need of a kind of can reducing thermal loss in industry, improves the efficiency of heating surface and kitchen range that structure is simplified are to solve Deficiency of the prior art.
