Description

The heating heat exchange box of phase-transition heat-storage

Technical field

The utility model relates to a kind of Heat supply and heat exchange case, especially a kind of heating heat exchange box of phase-transition heat-storage belongs to heat supply Equipment technical field.

Background technique

Phase-transition heat-storage heating is to utilize material when phase solid-liquid or liquid-gas change, and can absorb or release a large amount of latent heat Feature and the heat storage carried out or release, compared to traditional alternating temperature heat accumulation process, the temperature of material is several in phase transition process Remain unchanged, can be utilized in energy abundance in heating engineering in low-temperature phase-change material the heat storage in hot water is existed In phase-change material, heat supply is carried out using the phase transformation heat release of phase-change material in energy shortages, is widely used in paddy at present For hankering, i.e. paddy electricity is stored in phase-change material by night for electricity storage, and daytime is used in the heat accumulating type heat supplying process of heating.At present The basic composition of common paddy electricity phase-transition heat-storage heating includes reflux pump, electrically heated boiler, heat exchange box, heating heat exchanger fin and control Device, heat exchange box is interior to be arranged salt plug, and salt plug is interior filled with phase change heat storage material, and night use paddy electricity is added water by electrically heated boiler Heat exchange box circulation is passed through after heat, phase change heat storage material is by solid-state after heat exchange the temperature inside the box reaches the phase transition temperature of phase change heat storage material Mutually become liquid, absorb heat therebetween, then stop electric heating daytime, is exchanged heat using the heat stored in phase change heat storage material Water in case heats.Heat exchange box is the core component in phase-transition heat-storage heating system, and currently used heat exchange box structure is Multiple parallel salt plugs are placed equidistant in heat exchange box, heat exchange water inlet is arranged in the downside of heat exchange cabinet and perpendicular to heat exchange The side wall of case, heat-exchanging water, which enters in heat exchange box, goes out heat exchange box weight with the water outlet after salt plug progress heat exchange on the upside of heat exchange cabinet Newly enter grill pan stove heating, heat-exchanging water is substantially at advection state during this, and there are many water flow dead angle in heat exchange box, heat-exchanging water Water flow short circuit is easily formed between import and heat exchange water out, heat-exchanging water residence time in water tank is short, and easily cause heat exchange not fill part, Keep the temperature difference between import and outlet smaller, the higher recirculation water of water temperature can scatter and disappear largely in the approach for being back to boilers heated electrically Heat；The pyroconductivity for the phase-change material filled inside existing salt plug is very low, and salt plug leans on paracentral phase-change material at work Take a long time to can be only achieved operating temperature, and salt plug, since normal time service is under the condition of high temperature, phase-change material is in phase Volume can also change when change, if salt plug cover not tight or salt plug ontology because hot water or phase-change material corrosion reveal, It can not find that salt plug is revealed in time generally in the system of sealing state, and mostly phase-change material be inorganic salts or organic salt, Middle many types all can in phase-transition heat-storage system pipeline and the equipment such as pump cause to corrode, salt plug leakage will be to whole system Service life makes a big impact.The structure of heat exchange box and salt plug affects the overall heat exchange efficiency of heat exchange box in the prior art, The cycle-index of heat-exchanging water is increased, and is not easy to find in time when salt plug leakage, therefore, how to improve the heat exchange effect of heat exchange box Rate reduces the cycle-index of heat-exchanging water, reduces heat consumption of the recirculation water in circulating line, and prevents salt plug leakage to whole The influence in a system equipment service life is urgent problem to be solved in the prior art.
