TECHNICAL LEVEL

A heat exchanger is a technical device for exchanging heat, more precisely: a device made of a solid phase material that absorbs a spectrum / radiation of the appropriate wavelength, such as the sun, visible light or infrared reflected from the heat exchanger plate and for example, may be made of aluminum foil covered with a heat-absorbing titanium layer, as an example: TiNOX materials. Such a heat exchanger is intended for the exchange of heat carrier energy. The heat carrier (heat transfer fluid) flowing through the heat exchanger is a liquid or gaseous phase material that is carried! energy, for example: the flow of air flushing the heat exchanger and transferring heat to the room. The thermal insulation or other type of casing (housing) used in the heat exchanger system may be, for example, a transparent board, which transmits radiation of a suitable wavelength and has a low or high appropriate thermal conductivity. The flux forming elements may be fixed, cut, folded, cut or otherwise mounted on a heat exchanger plate or frame. These parts can be unscrewed, screwed, fastened to the heat exchanger, or may be integral with the heat exchangers. The coolant flow forming members are designed to direct the coolant flow in the desired direction. The flux forming member may be in the form of a wafer of various shapes, coated, for example, with photovoltaic or heat-absorbing material, and exposed to sunlight. Wave sources can be sources of energy waves, such as: sun, hot engine, furnace, etc.

The world-known heat exchangers generally have the following disadvantages: (i) in tubular or plate heat exchangers, the heat transfer medium flows in a laminar manner and has low mixing with the heat transfer layer formed on the walls and no efficient heat exchange between the heat exchanger walls and the heat transfer fluid; (ii) in perforated or transverse flow heat exchangers, losses are mainly caused by turbulent gaseous flow, resulting in loss of velocity and high local pressure losses; (iii) there is no uniform reciprocal flushing of the heat exchanger, each flow flowing on separate sides of the heat exchanger; (iv) When installing the heat exchangers vertically or at an angle, the optimal angle between the wave source and the surface of the absorbent heat exchanger is not maintained.

Pat. CN101761150, published 2010 June 30, 2006 describes a solar thermal energy storage and storage system utilizing solar energy. In this system, a plate heat exchanger is attached to the wall of the building, which has metal plates of various shapes, which are angled outwards at various angles and serve as vortex generators for gaseous material. Between this vortex generating panel and a heat source such as the sun, there is a heat dissipating material, such as glass, on the outside of the building, and the heat transfer flux is heated between the said material and the plate by means of vortexes. The present invention is used for heating or cooling the indoor space during the cold or warm season respectively. The present invention relates to plate single-sided heat exchangers, where the heat transfer fluid flows in a turbulent manner but has low mixing with the heat transfer layer formed on the walls and does not efficiently exchange heat between the heat exchanger walls and the heat transfer stream and produce high local pressure losses.

PREFERRED {LIVING OPTIONS

Coolant is the liquid or gas used to transfer heat from a hotter place to a colder place. During transfer, some liquid heat carriers may change the aggregate state, i.e. y. liquids convert to gas and vice versa.

As depicted in FIG. 1, the heat carrier flux (17) flowing along the heat exchanger plate (15) collects energy which is partially transformed / converted into kinetic and potential. The coolant flow (17) moves along / along the heat exchanger plate (15). When the laminar flow forming members (114) of FIG. 4, the coolant flow (17) is directed to one side and to the other side of the heat exchanger plate (15), thereby forming a turbulent laminar movement of the heat transfer fluid (17), resembling a serpent. Laminar flow of gas or liquid is the flow of thin layers without mixing the flows. In this case, the word "laminar" is to be understood as a snake-creep flow of the heat transfer medium along the heat exchanger plate (15), where that plate (15) is crossed where the forming elements are located (Fig. 4, 114). In this way, the heat transfer medium (17) moves along the heat exchanger plate (15) and, when a laminar gas flow is formed, is directed to the other side of the heat exchanger plate (15) by means of forming elements (Fig. 4, 1-14). This process is repeated until the flow of heat transfer medium (17) reaches the other end of the heat exchanger plate (15) and has reached maximum energy storage. During the flow process of such a heat transfer stream (17), the heat transfer stream (17) undergoes small local pressure losses due to an even variation in the laminar turbulent gas flow flow, since said forming parts are selected for such dimensions and spaced relative to each other and ) to ensure the optimum path for the heat carrier to achieve a minimum resistance force.

The forming elements (Fig. 4, 1-14) of the heat flux (17) are mechanically folded at a selectable angle alpha (a), adjusting them to the incident angle of the heat wave source to the heat exchanger plate (15). When the heat wave source is the sunlight (19), by forming the heat exchanger plate (15) on a vertical wall, the forming elements (Fig. 4, 1-14) are tilted to the sun (18) at an angle to ensure a minimum reflection coefficient, ie: The sun's rays should fall as steeply as possible on the plate collecting light energy. This positioning of the plates ensures the most efficient absorption of light energy.

The forming parts (Fig. 4, 1-14) have different shapes. Their shape depends on the required heat transfer angle and the amount of energy absorbed by the wave source. The various shapes of the heat transfer flux forming parts and their arrangement in the heat exchanger plate (15) are described below.

With respect to the heat exchanger plate (15), said forming members (Figs. 4, 1-14) are spaced apart so as to ensure the physical properties of the heat transfer stream (17), which allow the formation of a laminar flow, i. flow of the heat transfer medium (17) on the principle of least resistance without partial mixing by the snake creep, the gas flow passing through said heat exchanger plate (15) at the locations of the forming parts (Fig. 4, 1-14).

FIG. Fig. 7 shows a member (4) forming the heat carrier flow (17), which can be fastened, e.g. screwed or unscrewed, from the heat carrier plate (15) and can be replaced as needed with other Figs. 4, (1-14). The heat exchanger flow (17) forming member (4) is fastened by means of screws (20) to the fastener (21) which is in contact with the heat exchanger plate (15). The function of said fasteners can also be performed by rivets, roll-over structures and the like. The protective barrier (16), which is fitted with a heat exchanger plate (15), is fixed to the building wall (22).

FIG. Fig. 8 shows one embodiment of the heat exchanger which is interesting enough in practical terms. In this embodiment, the protective partition (16) functions as a window glass, the heat exchanger panel (15) functions as a window blind frame and the shutter panels as one part covered with heat absorbent material (working side), e.g. the other side is a light-reflecting material, for example: aluminum. Depending on the angle of rotation of the blinds, the entire system may change its role: absorbing or reflecting light. The shutters are mounted on the frame of the shutters, for example on the ropes arranged from the top to the bottom of the heat exchanger. Further, from the plane of the window, behind the plane of the frame of the blinds, there is a beam of scaled plates (22) forming a scaly wall, which is located immediately adjacent to the plane of the blind system. This scaling wall is formed by repetitive scaling plates forming arcuate recesses, which cause the snakes to move in the shape of a coolant. Let us consider the following example. When the sun's rays pass through the glass and fall on the heat-absorbing side of the blinds, the light energy is converted into thermal energy. This heat begins to rise and, due to the angle of the blind plate above, is directed towards the scales plate. There, the flow of coolant enters an arc-shaped recess and returns to the plane of the blinds. It is then re-directed towards the scaly plane. In this way, the flow of heat transfer medium moves in the shape of a snake movement and repeats until the heat flow reaches the top of the heat exchanger, through which it enters the room. The plaques of said scales may be made of transparent material and the shades of shades may be made of heat or electricity generating materials. The rear (scaled wall) and front (blinds) details can be collapsed and unfolded as blinds. If the rear scales are made of transparent material, the heat exchanger will pass light into the room. The heat exchanger can be used indoors and / or outdoors.

The heat exchanger (23) of the present invention can be used inside buildings by placing it on a window sill and facing the sun (18). The flow of warm coolant (17) heats the room and creates micro-ventilation that kills mold in cold bridges and also reduces dew on the interior windows. The heat exchanger (23) of the present invention may also be used to supply gas, such as warm air, to dryers of organic and inorganic materials for drying, for example, herbs, grains, biofuels or gravel. Said heat exchanger (23) can also be used for heating the supplied gas to furnaces, burners or boilers. In addition, this heat exchanger (23) can be used to generate electricity and to heat the gas supplied for various other purposes. This heat exchanger (23) can also be used to heat the supplied gas into mechanical devices. In addition, the heat exchanger (23) can be used to preheat the supply air to the ventilation or recuperation units.
