The present invention relates to a heating and cooling holder for vehicles, and more particularly, to a heating and cooling holder for vehicles that can increase the efficiency of transferring heat to the beverage in a cup holder, so that hot and cold beverages can be made fast for consumption.

The above object of the present invention is achieved by the heating and cooling holder for vehicles comprised of a heat insulating cup 100 where a container accommodating part 110 is formed with an upper part opened so that a beverage container can be accommodated, a heat exchange cup 200 installed in the container accommodating part 110 formed in the heat insulating cup 100, a circulation duct 300 installed so that an air suction port 310 and an air exhaust port 320 are formed in the heat exchange cup 200, a circulation fan 700 that circulates air while introducing air into the heat exchange cup 200 through the air suction port 310 and the air exhaust port 320 formed in the circulation duct 300, a radiation plate 400 heat-exchanging the air introduced into the heat exchange cup 200 by the circulation fan 700 to re-supply to the heat exchange cup 200 through the circulation duct 300, and a thermoelectric element 600 installed so that the radiation plate 400 can absorb and generate heat.

In an entrance refrigerator, a printed circuit board (PCB) on which heat generating components are mounted is disposed inside a housing such that air used to cool a heat sink of a cold air supply device cools the PCB, thereby preventing overheating of the PCB.

A solid-state cooling module includes a plurality of housing portions. Each of the housing portions houses a solid refrigerant substance. The solid-state cooling module is configured to heat or cool a heat medium flowing through insides of the plurality of housing portions. At least some of the plurality of housing portions are connected to each other in series with respect to a flow of the heat medium.

A thermally controlled cabinet such as a grow cabinet having an internal chamber for containing objects such as plants, with a temperature control system that accurately and precisely maintains the temperature inside of the chamber.

An automated aquarium frozen fish food feeder has a housing containing a cooling device and a dispensing device. Frozen fish food cubes dispensed into a basket melt before being accessible to fish. Melted fish food exits through openings in the basket of a size that prevent dispersal of the frozen cubes. The device structure minimizes heat exchange with ambient air. A carousel rotates to place a food container periodically in registration with a food outlet. A mechanism opens the bottom surface of the food container and dispenses food through the outlet aperture. The carousel surface is treated with friction-free coating. The carousel is removable from the carousel chamber for cleaning or filling. Different carousels are provided each dedicated to a particular size of frozen food cubes. The carousel chamber is included in a drawer below the cooling device for easy access for cleaning and for inserting selected carousels.

A set of headphones (1) comprises a pair of speaker units (3); a pair of ear pad portions (4); a plurality of temperature change modules (24) that are provided inside the pair of ear pad portions (4), and that heat and/or cool electrically so as to convey a temperature other than normal temperature to the user; and a temperature control unit (31) that drives the plurality of temperature change modules (24) on a rotating basis while shifting the phase of operation individually or in groups.

Disclosed herein are embodiments of a temperature-regulating containment system for actively heating and/or cooling a liquid to a desired liquid temperature, and methods of making and using such a temperature-regulating containment system, whereby the temperature-regulating containment system comprises: (i) a container having an internal cavity defined by a sidewall upwardly extending from a bottom wall, the internal cavity configured to contain liquid which has a liquid temperature; (ii) a temperature regulator operatively coupled to the internal cavity, the temperature regulator configured to regulate the temperature of the internal cavity and the liquid therein; (iii) a pressurizable chamber disposed between the internal cavity and the temperature regulator; and (iv) a pressure regulator operatively coupled to the chamber, the pressure regulator configured to regulate the pressure of the chamber.

Disclosed is a power generation device including a case including a through hole configured to pass therethrough in a first direction and form an inner surface, a duct disposed in the through hole of the case and having a flow path such that a first fluid flows in a second direction perpendicular to the first direction, a first thermoelectric module including a first thermoelectric device disposed on a first surface of the duct and a first fin disposed in the first thermoelectric device, a second thermoelectric module including a second thermoelectric device disposed on a second surface facing the first surface of the duct and a second fin disposed in the second thermoelectric device, a plurality of first guide portions coupled to the case and disposed on the duct while facing each other, and a second guide portion disposed on a third surface formed between the first surface and the second surface of the duct. Here, the second guide portion extends between the plurality of first guide portions in the second direction. Also, the plurality of first guide portions and the second guide portion each include a tilting surface, and a tilt angle of the tilting surface of the second guide portion differs from a tilt angle of the tilting surface of each of the plurality of first guide portions.

A refrigerator including an inner case having a storage chamber defined therein; a thermoelectric module configured to cool the storage chamber, wherein the thermoelectric module includes a thermoelectric element and a heat sink; a heat-dissipation fan assembly provided adjacent to the heat sink; a heat-dissipation cover spaced apart from the inner case, wherein the heat-dissipation cover has at least one outer intake hole defined therein and wherein the intake hole faces the heat-dissipation fan assembly; and a gasket configured to block a gap between the heat-dissipation cover and the heat-dissipation fan assembly.
