1. Field
The disclosure relates to a heating device, and more particularly, to a solar heating device.
2. Background
Since global warming causes abnormal climate change in seasons and the overdevelopment of industrial society causes serious environmental impact, a lot of disasters occur. Thus, many countries advocate utilizing sustainable energy and have signed climate protection agreements. Thus, there is a need for a device capable of utilizing solar energy for emergency situations (e.g., disasters) or outdoor activity.
A solar beam collection heater 21 in prior art as shown in
The disclosure provides a solar heating device, which comprises at least one incidence collector and a thermal container. The thermal container includes at least one light absorbing recess. At least one incidence collector focuses solar beams on a focal point. The light absorbing recess converts the energy of the solar beams into radiant heating (e.g., a black-body radiating source). Preferably, the focal point is located inside at least one of the light absorbing recesses.
The disclosure also provides a solar heating device, comprising at least one incidence collector and a thermal container including at least one light absorbing recess. At least one of the incidence collectors focuses solar beams on a focal point and includes an optical guide. The optical guide directs the solar beams to the focal point and locates the focal point inside the light absorbing recess so the light absorbing recess converts the solar beams into radiant heating.
The foregoing has outlined rather broadly the features and technical benefits of the disclosure in order that the detailed description of the application that follows may be better understood. Additional features of the disclosure will be described hereinafter, and form the subject of the claims of the disclosure. It should be appreciated by those skilled in the art that the conception and specific embodiment disclosed may be readily utilized as a basis for modifying or designing other structures or processes for carrying out the same purposes of the disclosure. It should also be realized by those skilled in the art that such equivalent constructions do not depart from the spirit and scope of the disclosure as set forth in the appended claims.
A more complete understanding of the disclosure may be derived by referring to the detailed description and claims when considered in connection with the Figures, where like reference numbers refer to similar elements throughout the Figures, and:
The disclosure is directed to a solar heating device. In order to make the disclosure completely comprehensible, detailed steps and structures are provided in the following description. Obviously, implementation of the disclosure does not limit special details known by persons skilled in the art. In addition, known structures and steps are not described in detail, so as not to limit the disclosure unnecessarily. Preferred embodiments of the disclosure will be described below in detail. However, in addition to the detailed description, the disclosure may also be widely implemented in other embodiments. The scope of the disclosure is not limited to the detailed description, and is defined by the claims.
The thermal container 120 further includes an outer wall 121, an inner wall 122 and a vacuum layer 123. The vacuum layer 123 is disposed between the outer wall 121 and the inner wall 122. Since the position of the light absorbing recess 140 does not include the vacuum layer 123 between the outer wall 121 and the inner wall 122, the position of the light absorbing recess 140 in the thermal container 120 is formed by a single recess wall instead of the outer wall 121 and the inner wall 122. By such design, the black-body radiating source of the light absorbing recess 140 directly conducts heat into the inside of the thermal container 120 to heat liquid 200. In addition, since the thickness of the outer wall 121 and the inner wall 122 is inversely proportional to the value of thermal conductivity, if the wall thickness of the light absorbing recess 140 is less than that of the outer wall 121 and the inner wall 122 of the thermal container 120, it is more efficient to conduct the heat into the thermal container 120 from the radiating source. Furthermore, in the embodiment, the thermal container 120 further includes, but not limited to, a cover 300 which seals the opening (not shown) of the thermal container 120 so as to rapidly heat the liquid 200.
