Definitions
- the invention falls within the technology of solar collectors and more specifically focuses on the design of solar receivers for Stirling disk.
- Stirling disk systems are electricity generating units that use solar radiation as a source of energy.
- the capacity of a single unit is between 3 and 50 kWe.
- the operating mode of a Stirling disk system is as follows: the concentrator reflects solar radiation towards the receiver that is located at the focal point of the concentrator. Solar radiation is absorbed into the receiver and it heats the gas (helium or hydrogen) of the Stirling engine at temperatures around 650 ° C. This heat is converted into mechanical energy in the Stirling engine. An electric generator converts this mechanical energy into electricity. To ensure that the reflected radiation affects the focal point throughout the day, a solar tracking system moves the concentrator continuously to follow the sun's path.
- the technology of solar receivers is developed based on the type of process in which it will be used, that is, the type of plant and the cycle used.
- the invention presented refers to the solar reception plant with disk and the cycle is that of Stirling.
- the technologies used for solar tower receiver plants are an application reference.
- Cavity receptor systems External receivers have absorption surfaces in direct view with the concentrators and depend on the direct absorption of the radiation.
- the cavity receptors on the other hand, have an opening through which the concentrated radiation passes until it reaches the surface of the receiver. The cavity ensures that most of the incoming radiation is absorbed by the internal surface of the receiver.
- the most used receivers for Stirling disk systems are cavity receptors.
- the receiver is located behind the opening to reduce the amount of heat lost and to decrease the intensity of the concentrated flow on its surface.
- the concentrated radiation that enters through the opening of the receiver diffuses into the cavity. Most of the energy is absorbed directly by the receiver, and virtually all of the rest is reflected or re-irradiated within the cavity to be subsequently absorbed.
- a cavity receiver two methods for transferring absorbed solar radiation to the working fluid of the Stirling engine have been identified.
- the first method consists in using a receiver of directly illuminated tubes, where small tubes through which the working fluid of the motor circulates are located directly in the region where the concentrated solar flow affects.
- the tubes form the surface of the receiver. In this way, the working gas is heated as it passes through the tubes heated by solar radiation.
- the second method that of reflux, uses a liquid metal as an intermediate heat transfer fluid.
- the liquid metal vaporizes on the rear surface of the receiver and condenses in the tubes through which the working fluid of the motor circulates. That is, it absorbs heat from the material that forms the receiver (which is hot from exposure to solar radiation) and then transfers it to the tubes through which the working gas of the engine circulates.
- This second type of receiver is called reflux because the vapor condenses and returns to be evaporated again.
- HTC Solar Solar heater head for generation of electric current from solar energy.
- Absorber with highly conductive and blackened (oxidized) material to homogenize the heat concentration.
- copper material which is welded to the exchanger tubes with high performance stainless steel (such as a tube jacket).
- Hybrid receiver system with sodium heat pipe Structure of the nickel powder element. Describes integration with burner system (hybrid).
- Combustion system for a hybrid solar receiver comprising a premixer that combines air and fuel to form the mixture to burn. There is an associated heat exchanger and in contact with the combustion chamber. This heat exchanger provides heat for the hybrid receiver when the sun's heat cannot be used as an energy source.
- US6818818 2004 Plano, TX Concentrating solar energy receiver It describes a system composed of a parabolic concentrator of high reflectivity to reflect the sun's rays on its concave side and a conversion module to which the concentrated solar radiation arrives.
- this conversion module there are two different receivers; a photovoltaic receiver and a receiving surface coupled to a thermal engine to produce electricity.
- the solar receiver includes a heat pipe that has a fluid inside.
- the heat pipe has two condenser portions arranged at two ends.
- an evaporator is included between both ends.
- An air manifold is coupled to one of the ends. This manifold has an air inlet and outlet.
- a liquid collector is coupled to the other end, with its respective inlet and outlet.
- the invention is a receiver with an internal cavity that reflects radiation.
- the receiver is contained in a reducing or inert atmosphere to maintain the properties of the reflective surfaces of the cavity. Heat absorption occurs in tubes arranged symmetrically with respect to the main axis of the receiver. In addition there is a quartz window at the entrance of the device to reduce convection losses
- the new design thus increases the efficiency of the disk and reduces manufacturing and operation and maintenance costs. It also offers the possibility of:
- the invention consists of a new stirling disk receiver that meets the previously defined requirements.
- the designed receivers comprise the following components: tubes, manifolds, tanks and domes.
- Tubes form the surface where the concentrated sunlight beam strikes. They are arranged very close to each other so that the surface has few holes and the incident radiation can be used to the maximum.
- collectors are the areas where the pipes are welded, so that the flow that flows through the pipes communicates with the tanks.
- Deposits The deposits are the interior areas of the collectors, from here the working gas is distributed to each of the tubes.
- Domes There are two domes: the one in charge of housing inside the regenerator (or heat exchanger capable of absorbing heat from the working gas, storing it and transferring it to close the cycle being, of the intercarriators that contains the engine, which greater volume of thermal energy handles) and the expansion dome (or dome), which is the area where the working gas is at a higher temperature.
- the receiver design claimed in this invention called a coil receiver, is composed of a series of tubes that run perpendicularly from one collector and arrive perpendicularly to the other.
- the surfaces where the tubes are welded to the collectors are parallel to each other and perpendicular to the entrance of the tubes.
- Each tube has two 180 ° curves in its path so that each tube travels almost three times the distance between the two collectors.
- each tube leaves the collector of perpendicular origin and in a straight line towards the destination manifold and before reaching the destination manifold it rotates 180 ° down slightly in height and returns in a straight line, by a horizontal plane parallel and inferior to that of the gone, towards the origin collector and before reaching the origin collector, rotate again 180 °, going down a little more in height, heading straight again by a parallel horizontal plane and inferior towards the destination collector, where it enters perpendicular and connects by welding.
- the welding point of the tube to the source manifold is higher in height than the welding point of the tube to the destination manifold.
- each tube consists of two semicircles (the 180 ° curves) and three straight parts that are: the central part, between curvature and curvature, and the two straight lines of the ends of the tube, which are the ones that connect to the collectors
- the three straight parts are parallel to each other according to horizontal planes, since they are all at different heights, while the straight lines of the ends are in the same vertical plane, parallel to the vertical plane that contains the center line.
- each tube Seen from the face of incidence of solar radiation, each tube is arranged in such a way that the straight parts of the tube form a surface without gaps between tubes and without shading of some parts on others.
- This design of the receiver in the form of a coil allows having the tube developed in two different planes, the dilatations (consequence of high temperatures) are very little restricted, which will initially reduce the appearance of tensions in the tube. Therefore, a priori, this design will present few breakage problems due to excessive stresses in the material.
- the arrangement in different planes of the tubes will also allow a better cooling of the receiver by means of a fan when the temperature of the material is excessively high. As there is greater gap between tube and tube, the heat transfer by convection between the fan air and the outer surface of the tubes becomes more effective.
- the surface seen by the concentrated solar radiation beam is completely compact, that is, there are no gaps between the tubes if viewed from the predominant direction in which the radiation strikes.
- a drawback that can be found in this design is that by increasing the length of the tubes and decreasing the overall passage area (sum of the passage areas of all the tubes) the associated head loss increases. This could result in a loss of unquantified engine power. But the loss of power discussed above is compensated by the increase in gas temperature. Having tubes of greater length, the temperature reached by the gas after passing through the receiver is higher, for the same surface temperature.
- Another advantage is that the manufacture of the tubes does not involve technical complications.
- the simplest procedure would be to cut a straight tube to the appropriate length and then make the corresponding curvatures and angles to give it the desired final shape.
- the manufacturing process of the receiver it comprises the following stages:
- the receiver model presented as well as its manufacturing procedure comply with the design restrictions and improve the overall thermo-mechanical behavior of the receivers known in the state of the art.

- Figure 4 Perspective view of a tube
- Figure 1 shows the design of a state-of-the-art receiver, corresponding to patent DE19527272, in which it can be seen that it is formed by the tubes (1), the collectors (2), the expansion dome or of the dome (3) and the dome that houses the regenerator (4).
- the tubes (1) are identical to each other and have a loop-shaped geometry (note: the references that appear here do not correspond to those of the original document, have been modified to achieve greater consistency with the description of the invention claimed in this document).
- Figure 2 shows the different views of the solar serpentine model receiver and in figure 3 the exploded view.
- the receiver is formed by a series of tubes (1), which are held at both ends by two collectors and resting on the dome regeneration (4) and expansion (3).
- the receiver comprises 28 tubes (1) of approximately 800 mm in length, identical to each other and leaving perpendicularly from one collector (2) to reach perpendicularly to the other (2).
- the surfaces or plates (5) where the collectors (2) are welded are parallel to each other and perpendicular to the entrance of the tubes (1).
- Each tube (1) leaves the source manifold (2) in a straight line (12) towards the destination manifold (2) and before reaching the destination manifold it rotates along a 180 ° curve (10) down slightly in height and returns in a straight line (11), along a parallel horizontal plane and inferior to that of the first leg (12), towards the original collector (2) and before reaching the original collector it rotates again according to a 180 ° curve (10 ), lowering a little more in height, heading straight (12) along a parallel horizontal plane and lower, again towards the destination manifold (2), where it enters perpendicular and is connected by welding.
- each tube has two curves (10) of 180 ° in its path so that each tube (1) travels almost three times the distance between the two collectors (2).
- each tube consists of three straight parts (12, 11, 12) and two curved parts (10).
- the two curves (10) are 11.1125 mm radius semicircles. and the straight parts are: the center (11) (between curvature (10) and curvature (10)) of 220 mm and the ends (12) (between curvature (10) and exit or entry of a collector (2)) of 255 mm (here are included the 3 mm of tube (1) that are inserted into the manifold (2) for welding).
- the central part (11), between curvature (10) and curvature (10), and the two straight lines of the ends (12) of the tube, are parallel to each other according to horizontal planes, since all of them are at a different height, while the straight lines of the ends (12) are in the same vertical plane, parallel to the vertical plane that contains the center line (11).
- each tube (1) Seen from the face of incidence of solar radiation, each tube (1) is arranged in such a way that the straight parts (11, 12) of the tube form a surface without gaps between tubes and without shading of some parts on others.
- Figure 6 shows the manifold (2).
- a row (20) all tubes (1) that have that collector as origin are welded and in the parallel row (21) all tubes that have that collector as destination are welded. This arrangement prevents the tubes of one (20) and another row (21) from coming into contact.
- the distance between centers of tubes (1) of the same vertical row is equal to six times the diameter of the tube.
- This system is specially designed for application in Stirling disk receivers but its extension to other fields of the industry that require similar characteristics is not ruled out.
