The present invention relates to an improvement of a capsule for a solar collector including a solar collector and a microcomputer for controlling the solar collector to follow the movement of the sun, and in particular to the ambient temperature of the microcomputer. In order to prevent a malfunction or a mistaken operation, furthermore, in order to prevent a change in the sensitivity of the solar direction sensor and a decrease in the conversion efficiency of the solar cell, heat in the capsule is effectively released to the outside of the capsule.

1 is a perspective view for explaining one example of the solar collector capsule proposed by the present applicant, Figure 2 is an enlarged rear view showing an embodiment of a solar collector capsule according to the present invention, (1) is a cylindrical gas part, (2) is a dome-shaped head of a transparent body, and by these, it constitutes the capsule 3 for a solar collector, and this capsule 3 is in use. As shown in the drawing, the solar collector 10 is housed.

The photovoltaic collector 10 includes a plurality of lenses 11 for condensing sunlight (for example, 7 sheets and 19 sheets), and a photovoltaic direction sensor 12 for detecting the direction of the sun. For the optical direction sensor, if necessary, see subsection 55-144926, subsection 56-99993, etc.), a support frame 13 for maintaining them integrally, and the first frame for rotating the support frame 13. A rotating shaft 14, a first motor 15 for rotating the first rotating shaft 14, a support arm 16 for supporting the lens 11 to the motor 15, and the first rotating shaft. A second rotary shaft 17 disposed orthogonally to 14, a second motor 18 for rotating the second rotary shaft 17 as shown in FIG. 2, and the solar direction sensor A microcomputer 19 for controlling the first motor 15 and the second motor 18, a power supply transformer 20, and the like in response to the output signal of 12; sensor( 12 controls the first motor 15 and the second motor 18 by operating the microcomputer 19 so that the lens 11 always faces the direction of the sun. 11) is introduced into the unillustrated optical conductor cable in which the light receiving end surface is disposed at the focal position P of the lens, and through this optical conductor cable, it is necessary to arbitrarily desire and location, for example, illumination. We let you send to point to say.

Thus, in the solar collector as described above, in order to protect the solar collector from weather, dust, etc., the solar collector is housed in a capsule (3) as shown in the figure, but in the capsule A microcomputer 19 which controls the light collector 10 to follow the movement of the sun, and a power transformer 20 for control and power for tracking this solar collector to the movement of the sun are accommodated. Since the temperature inside the capsule rises due to the heat generation of the power transformer or the like, the microcomputer may fail or malfunction may occur.

The present invention is made to solve the above-described deficiencies of the prior art, and as shown in FIG. 2, the heat absorbing device 21 is disposed near the heat generating element 20 such as a power supply transformer in the capsule. (21) is connected to a heat dissipation device 23 disposed outside the capsule through heat transfer means 22 such as a heat pipe.

Therefore, according to the present invention, it is possible to effectively discharge the hot air in the capsule to the outside of the capsule, it is possible to prevent the malfunction, error operation and the like of the microcomputer.

In addition, since the temperature rises due to the solar energy incident into the capsule through the head transparent body in addition to the heating element as described above, in order to prevent a malfunction or a malfunction of the microcomputer caused by such heat, moreover When the solar cell 5 is provided around the detection sensitivity and change of the solar direction sensor and the light receiving surface of the solar light collecting device, in order to prevent the degradation of the conversion efficiency of the solar cell, as shown in the figure The heat absorbing device 24, the heat dissipating device 25, and the heat pipe 26 connecting them may be provided to lower the temperature of the entire capsule, and may be directly absorbed in the vicinity of the microcomputer 19. An apparatus 27 may be provided to connect the heat absorbing device 27 to the heat radiating device 29 provided on the outside of the capsule 3 via the heat pipe 28. It will be readily understood that (23), (25), (29) and the like may be forced air cooling or water cooling.

3 is a view showing an example of one variation of the heat absorber, the heat pipe, and the heat radiator shown in FIG. 2, and the heat absorber 21, the heat pipe 22, and the heat radiator 23 are typical. Although unevenness is indicated, this modified embodiment allows the heat pipe 22 to move in the direction of the arrow and, during normal use, dissipates heat in the capsule outside the capsule at the position shown in FIG. 3 (a). It is.

However, when the external temperature is extremely low, the temperature in the capsule is lowered beyond that and the microcomputer fails, the detection temperature of the solar orientation sensor decreases, or the conversion efficiency of the solar cell decreases. ) In the direction indicated by arrow A in the direction shown in FIG. 3 (b), and the heat in the capsule is not released to the outside, and thus the temperature in the capsule is kept at an appropriate temperature to prevent breakdown or malfunction of the microcomputer. You can do it.

At this time, as shown in FIG. 4, for example, the movement of the heat pipe, a heat insulating member 30 having a screw 30a at its distal end is provided with a screw hole of the heat pipe 22 outside the capsule. 22a), the heat pipe 22 is brought into the state of FIG. 3 (b) by pushing the heat insulating member 30, and the third heat insulating member 30 is pulled out. can be in the state of a).

As apparent from the above description, according to the present invention, the temperature in the capsule can always be maintained at a suitable temperature by a simple configuration, and therefore, a malfunction or malfunction of the microcomputer installed in the capsule can be prevented, The sensitivity of the direction sensor or the conversion efficiency of the solar cell can be maintained satisfactorily.
