Abstract
The invention discloses a phase transition heat storage electronic heater; an electric heating tube is mounted on the bottom of the irradiator shell; the phase transition heat storage agent is filled in the upper part of the irradiator shell; when the electric heating tube is electrified to operate, the phase transition heat storage agent absorbs heat energy to become the fluid state from the solid state, supplies heat energy through the irradiating fins of the irradiator and storage and stores part of the heat quantity in the phase transition latent heat mode. When the electric heating tube is powerdown and stopped from being heated, the phase transition heat storage agent releases the stored latent heat to become the solid state from the liquid state and supplies heat energy continuously through the channel pipe and the irradiating fins of the irradiator. The power energy is saved through the frequent electrification and powerdown while the sustainable heating of the phase transition heat storage electronic heater is guaranteed.
Description
Affiliated technical field
The present invention relates to a kind of heating system art, particularly a kind of phase-change heat-storage electrical heater of forming by radiator casing, tube channel, fin, electric heating tube, phase-change thermal storage agent etc.
Background technology
In the prior art, electrothermal heating apparatus is widely used, the most common electric heating oil raised path between farm fields warmer, and it is in the housing of electric heating oil raised path between farm fields, pack into heat-conducting medium oil and electric heater.During use, the electric heater heating power has heated heat-conducting medium oil, reaches the heating purpose by the housing heat radiation.Though this electric heating oil raised path between farm fields can produce the heat heating when switching on, after the outage, because heat-conducting medium oil ratio anharmonic ratio heat is all very little, heat storage capacity is poor, cools down very soon, with equilibrium at room temperature, can not long-time energy-conservation heat supply after outage, thereby limited universal heating and used.
Summary of the invention
Task of the present invention provides a kind of phase-change heat-storage electrical heater, and it can effectively overcome the weak point that can not heat for a long time after the prior art products outage, can long-time heat supply heating reach energy-saving effect after outage.
Task of the present invention is finished like this: in a radiator casing, the electric heating tube of packing in the bottom of radiator, the phase-change thermal storage agent is filled on top, during electric heating tube energising work, the phase-change thermal storage agent absorb heat by solid-state degree be liquid and by fin heat radiation heating the time mode with latent heat of phase change stored the part heat, when the electric heating tube outage stopped to heat, the stored latent heat of phase-change thermal storage agent release was become solid-state again by liquid state, and the phase transformation exothermic process has prolonged outage back heating duration.
Beneficial effect of the present invention is, just replaced heat-conducting medium oil of the prior art with the phase-change thermal storage agent, just can prolong heating time after outage stops heating, reaches effects of energy conservation and environmental protection.
Description of drawings
Accompanying drawing is a structural representation of the present invention
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples
In the accompanying drawing, in a radiator casing 1, at its bottom electric heating tube of packing into, phase-change thermal storage agent 5 is filled on top, the outside of radiator passage pipe 2 is welded with fin 3, plays thermolysis, produces heat during electric heating tube 4 energising work, absorbed by the solid-state liquid state that becomes by phase-change thermal storage agent 5, and by radiator passage pipe 2, fin 3 heat radiation heating.When electric heating tube 4 outages stopped to heat, phase-change thermal storage agent 5 discharged stored latent heat, and by radiator passage pipe 2, fin 3 continuation heating, phase-change thermal storage agent this moment is become again solid-state by liquid state, and reciprocation cycle makes the long heat of phase-change heat-storage electrical heater heat.
