Description

  The present invention relates to a hot wire transformer for converting low temperature hot water close to normal temperature into high temperature hot water.

  Exhaust hot water from the cooling systems of many devices operating at computer centers, etc. is discharged in large quantities, but is low-temperature hot water that is close to room temperature. Can't get.

  Such low-temperature waste heat water cannot be converted to a high temperature without loading with other energy, so that the efficiency of reuse is poor and it is discarded as it is. Therefore, as a whole, a large amount of heat is wasted.

  Although there is a low temperature, there is no effective technique for obtaining a high temperature without loading other energy in a system having a large amount of heat as a whole.

  The present invention has been made in order to solve the above-described problems. Although the temperature is low, it is possible to obtain a high temperature without loading other energy in a system having a large amount of heat as a whole. The purpose is to realize a heat-wire transformer.

In order to achieve such a subject, the present invention has the following configuration.
(1) a heat sink having a surface that is heated by the primary fluid and emits heat rays;
A main reflector that is arranged opposite to the heat sink and reflects the heat rays to collect the light at the focal position;
A pipe member that is disposed at the focal position and heated by the heat rays reflected from the main reflector, and through which a secondary fluid flows;
A heat ray transformer comprising:

(2) A sub-reflection plate is provided between the heat radiating plate and the pipe member to reflect a heat ray from the main reflection plate and the pipe member and collect the light on the pipe member at the focal position. The heat ray transformer according to (1).

(3) The heat radiation transformer according to (1) or (2), wherein the heat radiating plate has a black body as a surface that radiates the heat rays.

(4) The heat ray transformer according to any one of (1) to (3), wherein the pipe member has a black body surface.

(6) The heat ray transformer according to any one of (1) to (5), wherein the primary fluid is an exhaust heat fluid that has cooled the device.

According to the configuration of the present invention, the following effects can be expected.
(1) It can be easily converted into a temperature range in which heat can be effectively used by applying to a heat source that does not reach a very high temperature, for example, exhaust heat water of a cooling system for various heating elements such as a CPU, engine, and motor of a computer. Therefore, it is possible to effectively use the energy of the heating element near the normal temperature plus α that has been wasted.

(2) By taking a sufficient area ratio between the radiation plate of the heating element and the pipe member, it can be efficiently converted to a high temperature without loading external energy.

  Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a heat ray transformer to which the present invention is applied.

  The heat generating part of the device 1 is cooled by the cooling water W1, and the exhaust heat water W2 is output. The temperature of the exhaust hot water W2 is a normal temperature plus a low temperature α. The exhaust heat water W2 is input as a primary fluid to the heating element 2 having a predetermined capacity, and is heated and discharged as exhaust heat water W3. The heating element 2 has a heat radiating plate 21 having a predetermined area, and radiates heat rays H that are orthogonal to and parallel to the surface of the heat radiating plate 21 heated by the primary fluid W2.

  A plurality of (four in the figure) main reflectors 31, 32, 33, and 34 are arranged opposite to the heat radiating plate 21 to reflect the parallel heat rays H and collect them at the focal position. Pipe members 41, 42, 43, and 44 through which the secondary fluid W4 flows are arranged at the focal positions of the main reflectors 31, 32, 33, and 34, and the heat rays reflected from the main reflector and collected. Heated by H.

  Further, between the heat radiating plate 21 and the pipe members 41, 42, 43, 44, the pipes located at the focal position by reflecting the heat rays from the pipe members 41, 42, 43, 44 facing the pipe members. Sub-reflecting plates 51, 52, 53, and 54 for condensing light on the member are provided.

  The pipe members 41, 42, 43, and 44 are formed by bending one pipe, and a part of the exhaust heat water W3 of the heating element 2 is supplied as a secondary fluid W4 from one end side of the pipe member 41, and is heated at a higher temperature than the other end. The output fluid W5 converted into is discharged.

  FIG. 2 is a cross-sectional view showing a main part of a heat ray transformer to which the present invention is applied. The main reflectors 31, 32, 33, and 34 that reflect parallel heat rays H from the radiator 21 that radiates the heat of the heating element 2 are made of a material such as AL or a semi-cylindrical or semi-cylindrical type whose surface is mirror-coated. The pipe members 41, 42, 43, and 44 are arranged at a focal position that has a close shape and is connected by the parallel heat rays H from the heat radiation plate 21.

  The heat radiating plate 21 is painted black so as to be close to a black body to enhance the radiation efficiency of the heat ray H. Parallel heat rays (electromagnetic waves) H radiated from the heat sink 21 close to the black body are reflected by the cylindrical main reflectors 31, 32, 33, and 34.

  Pipe members 41, 42, 43, and 44 through which the secondary fluid W4, which is disposed at the focal position of the main reflectors 31, 32, 33, and 34 having a cylindrical reflection surface, are also painted black, thereby improving the efficiency of heat ray absorption. It is increasing.

  Further, the back side of the sub-reflecting plates 51, 52, 53, and 54, which reflects the heat rays from the main reflecting plate and the pipe member and collects the condensed light on the pipe member at the focal position, also faces the heat radiating plate 21. Since a part of the heat ray H from 21 is received, it is painted black to increase the absorption efficiency of the heat ray.

  The heat ray H radiated from the heat radiating plate 21 is in the infrared region of 5 to 20 μm, is radiated from the heat radiating plate 21 efficiently, is reflected by the main reflector, focuses on the pipe member position, and efficiently absorbs heat. It has a structure.

  Since the secondary fluid W4 circulating through the pipe member is in a temperature zone close to room temperature, the surface area A of the main reflector is increased as much as possible in order to increase the temperature conversion ratio. On the other hand, the surface area B of the pipe member is made as small as possible in consideration of the flow rate of the secondary fluid W4 flowing therethrough.

  Here, according to the black body theory, heat corresponding to the area ratio A / B moves to the pipe member side. This corresponds to an electrical transformer, and the temperature corresponds to a voltage that can be transformed. The area ratio (more precisely, the fourth root ratio of the area) corresponds to the winding ratio of the transformer. In that sense, the configuration of the present invention can be referred to as a heat ray transformer.

  The secondary fluid W4 flowing through the pipe member is heated by the absorbed heat, and ideally the temperature of the pipe member rises higher than the temperature of the main reflector. Here, it is important to take a sufficient area ratio A / B in consideration of heat loss. Moreover, the heat conversion efficiency can be further improved by arranging the configuration of the present invention in a vacuum.

  In the embodiment, the primary fluid and the secondary fluid are exemplified as water used in a normal cooling system, but other fluids may be used. In the embodiment, a part of the exhaust heat water W3 of the heating element 2 is supplied as a secondary fluid W4, but the secondary fluid W4 may be an independent circulation system.

It is a perspective view showing one embodiment of a heat ray transformer to which the present invention is applied. It is a cross-sectional view which shows the principal part of the heat ray transformer to which this invention is applied.
