Abstract

The invention relates to energy field and is used for heat-accumulation. Modular heat accumulator contains isolated capacities with two different materials with different melting point temperatures and heat accumulating.

The modular heat accumulator can be used separately as exchangeable heat capacities, connected into bigger heat accumulating module units, integrated in to other systems.

Description

The invention relates to the field of energy and can be used to store heat, conventional thermal tanks with water warm up quickly and occupy quite a large space. It is important to have a compact and receptive heat capacity. A number of technical solutions are known that use a variety of fusible materials that can store more energy. The closest analogue is given in the UA14577U patent.

The present invention proposes to store heat using two different melting point materials: a higher melting point material at the center of the device, a lower melting point material outside the device. the unit works as a one-way heat accumulator. Its main disadvantage is that it cannot function until the inside is completely warmed up. It requires a great deal of heat and time.

The present invention overcomes these drawbacks and provides additional advantages.

Two different fusible materials are arranged in opposite directions: faster and lower fusible material is in the center of the device, while higher fusible material is in the outside of the device. In addition, the materials are separated by an intermediate heat accumulator - sand. the unit has a spiral of incoming and outgoing heat flow. These solutions allow the heat accumulator to operate in a continuous mode, i.e. simultaneously accumulating and releasing heat. Only dry materials used for the heat storage device allow for the creation of a simple, insulated heat storage module that can operate in any position in space, combine individual modules by connecting them in a row, plane or spatial heat storage system. Modular heat accumulators can be used independently or as an integral part of other systems, such as a home.

The essence of the invention

The object of the present invention is to provide a device that accumulates a higher amount of heat quickly and sustainably.

Applying a modular principle, make a single unit - a module simple to manufacture, easy and quick to copy, universally applicable. The invention utilizes two materials that melt at different temperatures: the lower melting material is in the center of the device, and the higher melting material is placed outside the device. The primary module of the unit itself may be cylindrical (one tube inserted into the other), rectangular parallelepiped or other geometric shape. Geometric shapes can be selected according to the needs of the heat storage application in the particular circumstances. The simplest form of the module could be pipes or hollow cylinders.

All materials used in the unit are dry and insulated from interactions with the environment and other materials. Only thermal flows circulate between individual materials. In a concentrically filled unit, there are two heat transfer coils: one located externally to the incoming heat, closer to the walls of the higher melting material, and the other, the heat transfer coil, located in the center of the unit. The two meltable materials are separated by an intermediate: sand or other heat-transferable filler.

BRIEF DESCRIPTION OF THE INVENTION • The two different melting point materials used are bonded together via an intermediate, a sand medium.

• Material with a higher melting point is centrally located on the outside of the unit, while material with a lower melting point is placed in the center of the unit.

• The insulated, dry materials inside the heat storage module allow the module to be used in any desired position.

• Fusible materials may be enclosed in closed capillary - porous containers.

• Heat-accumulating material containers are wrapped in a heat-reflective coating and have a heat-insulating casing.

• Two heat transfer coils are used: one (incoming heat coil) is located closer to the outside of the unit; the other (the spiral of outgoing heat) is located at the very center of the thermal module.

• A modular heat accumulator can simultaneously collect external heat and release accumulated earlier heat.

• The modular heat accumulator has two interconnection connections to other modules or other systems.

• Heat storage modules can be connected to each other in different ways: linear, planar, spatial.

• Modular heat accumulators can be used separately as exchangeable heat capacities; connected to larger blocks of heat storage modules; integrated with other systems such as home heating.

All these features give the modular heat accumulator additional advantages.

The unit operates in the following way: From the outside environment, the heat transfer coil 7 heats the sand 3 through the coil walls. The hot sand 3 transfers heat to all directions. The heating coil 7 is located closer to the wall which, on the other side, has a higher melting point material 4, the latter being heated faster than other internal filler materials. The sand also heats the lower melting material heater 2 contained in an insulated container, which heats up and passes the chromium to the outgoing heat coil 1. The heat reflecting material 5 and the heat insulating material 6 are used to retain heat. Once they have reached their melting point, the materials will begin to dissolve and the temperature will remain constant for some time until the materials begin to rise when dissolved. Part of the external heat is temporarily used to melt the materials and will be returned when the materials cool. Properly selected materials with high melting temperatures allow heat to accumulate several times more than analogous containers with water. The internal and external melting points of the materials may vary between 20-50 ° C. As the internal medium cools, the heat accumulated outside will be transferred to the interior as the melting point of the material is significantly lower. Fusible materials may be contained in capillary-porous enclosures. In the drawing, FIG. 1 shows the opposite directions of the incoming heat flow 9 and the outgoing heat flow 10. The opposite direction of flow flows allows the maximum amount of heat to be absorbed. Figure 3 shows that the individual heat storage modules can be combined into more general systems. Linear, planar, spatial or combined connections allow you to create whatever heat storage system you want. Modular heat accumulators can be combined according to the required amount of heat, according to functional or spatial application - how much and what can be arranged in space. Individual or block heat accumulators can be replaced because the heat accumulated inside can be retained for some time. Modular heat accumulators can be used in a wide range of applications: home construction, industry, transport and more.
