Provided is a liquid heating apparatus capable of heating fluid such as peroxosulfuric acid solution to high temperature in a short time. The heating apparatus includes: a flow channel member forming a flow channel 4 allowing liquid to flow and having flow channel thickness of 10 mm or smaller, the flow channel member composed of material transmitting near-infrared rays; and a near-infrared heaters 7, 8 placed over the outside of at least one of opposite flow channel surfaces of the flow channel and heating the liquid in the flow channel. The liquid flowing through the flow channel is instantaneously and evenly heated using near-infrared rays. It is preferable that spacers 6 be further provided within the flow channel 4 in order to limit the volume of the flow channel. Since not only the residence time in the heating apparatus can be shortened but the possible largest heat transfer area can be also maintained by decreasing the volume of the flow channel of the heating apparatus and by increasing the flow velocity in the heating apparatus, it is possible to increase the temperature of liquid to be heated to high temperature in a very short time even if the preset temperature of heat transfer surfaces is low.

Recovery system of the heat dissipated by luminaires, comprising at least one lighting appliance (1), or luminaire, which has a LED lamp (2), or a lamp or bulb, or other light generating means, featuring a thermal transmission means near the source of light, such a thermal transmission means being associated to a heat exchanger through which circulates a fluid (8), where in the case of using LEDs, the thermal transmission means is a transmitter or radiator (4) in contact with the base or supporting plate of the LEDs, and arranged at the bottom of a heat exchanger (5), while if the luminaire has lamps or bulbs, the thermal transmission means is a reflector, upon which in a surrounding manner a casing leaving an interior space defining a heat exchanger is provided.

Provided are a lamp and a heating device which are capable of effectively preventing a seal portion from being overheated with a simple structure. A lamp (1) includes: a tube portion (11) in which a filament (13) including a coil portion (14) is contained; a seal portion (12) filled with a metal foil (16) connected to an end of the filament (13); and an overheat preventing portion (30) covering a part of an outer surface (11a) of the tube portion (11).

A fluid temperature control device is improved so as to be simple in construction, to provide a uniform fluid temperature and to heat even a fluid having a low light absorption rate. A fluid temperature control device includes a tubular inside container (20), a tubular outside container (22) surrounding the inside container (20), and a heating lamp (25) inserted into the inside container (20). Metallic fins (28a, 28b) are provided on inner and outer circumferential surfaces of the inside container (20) in such a manner as to erect from the surfaces, respectively. Working fluid is caused to flow in a flow path (21) between the inside container (20) and the heating lamp (25) and cooling water in a flow path (23) between the inside container (20) and the outside container (22). Infrared rays from the heating lamp (25) heat the working fluid and heat absorption into the cooling water cools the working fluid. This fluid temperature control device is used to control the temperatures of a plurality of process chambers equipped on, for instance, a reaction processing device. A plurality of the temperature control devices are disposed near the reaction processing device. Each temperature control device is exclusively assigned to each of a plurality of portions of the process chamber. Each temperature control device supplies the temperature-controlled working fluid to each portion of the process chamber.
