Abstract
The utility model relates to a combined phase changing material heat storage device, which is provided with a casing. Spheres, or cylinders are piled in the casing or heat storage units of a plate shape body are piled in the casing in a longitudinal interval. The heat storage units are divided into a plurality of heat storage unit areas from top to bottom. Phase changing materials of the same phase changing temperature are put in the heat storage units in each heat storage unit area. The phase changing temperature of the phase changing materials which are put in the heat storage units in the heat storage unit area is from low to high or from high to low, along the flow direction of heat storage liquid. The utility model has the advantages that the utility model can enhance 10-25% the heat releasing speed of heat storage, enhance 10-30% system efficiency, and make the heat releasing speed rate of the heat storage obviously uniform.
Description
The utility model relates to a kind of multiple phase change materials thermal storage equipment.
Latent-heat storage has obtained important application at aspects such as solar power system, heat utilization system and central air-conditioning electric power peak load shiftings.The encapsulation type latent-heat storage is one of main accumulation of heat form.In the encapsulation type thermal storage equipment, nearly all adopt same phase-change material at present, because the continuous variation of phase transition process thermal resistance causes the accumulation of heat heat release rate constantly to reduce, it is more and more littler that heat-transfer fluid is imported and exported the temperature difference.In actual applications, often increase the stability that the interior thermal storage unit quantity of equipment is kept system's operation.
The purpose of this utility model provides a kind of multiple phase change materials thermal storage equipment, overcomes because the variation of phase transition process thermal resistance causes accumulation of heat heat release rate and heat-transfer fluid to import and export the variation of the temperature difference stability of raising system operation.
The utility model is taked following measures in order to achieve the above object:
The multiple phase change materials thermal storage equipment, it has housing, in housing, be stacked with spheroid or cylinder or longitudinal separation and be stacked with the thermal storage unit of plate body, thermal storage unit from top to bottom is divided into a plurality of thermal storage units district, be placed with the phase-change material of identical phase transition temperature in the thermal storage unit in each thermal storage unit district, along the thermal storage fluid flow direction, the phase transition temperature of the phase-change material of being put in the thermal storage unit in the thermal storage unit district is respectively equipped with heat-accumulating process fluid course and heat release process fluid runner for or from high to low up and down at housing from low to high.
Advantage of the present utility model:
1) longshore current body flow direction has been arranged two or more different thermal storage unit of phase transition temperature (schematically drawing among the figure 5 kinds);
2) almost phase transformation simultaneously of different phase change material unit, and finish phase transformation simultaneously;
3) heat transfer temperature difference of phase transition process, promptly the difference of the phase transition temperature of fluid temperature (F.T.) and phase-change material almost can keep evenly, thereby keeps the uniformity of fluid flow direction heat flow density;
4) in the phase transition process, the heat-transfer fluid outlet temperature changes and obviously reduces;
5) theoretical and experimental study shows, the accumulation of heat heat release rate can improve 10～25%, and system effectiveness improves 10～30%, and the accumulation of heat heat release rate is obviously even.
Use: the multiple phase change materials thermal storage equipment can be applicable to solar power system, space heat control system, earthbound solar energy heat utilization, and central air-conditioning latent-heat storage (cold) system and other industrial heat utilization system.
Elaborate below in conjunction with accompanying drawing:
Fig. 1 is an I type multiple phase change materials thermal storage equipment structural representation;
Fig. 2 is an II type multiple phase change materials thermal storage equipment structural representation.
The multiple phase change materials thermal storage equipment has housing 8, in housing, be stacked with spheroid or cylinder or longitudinal separation and be stacked with the thermal storage unit 9 of plate body, thermal storage unit from top to bottom is divided into a plurality of thermal storage units district 1,2,3,4,5, be placed with the phase-change material of identical phase transition temperature in the thermal storage unit in each thermal storage unit district, along the thermal storage fluid flow direction, the phase transition temperature of the phase-change material of being put in the thermal storage unit in the thermal storage unit district is respectively equipped with heat-accumulating process fluid course 6 and heat release process fluid runner 7 for or from high to low up and down at housing from low to high.
