A flow-guiding rod includes a cooling channel provided in a rod portion of the flow-guiding rod, and a coolant inlet pipe and a coolant outlet pipe provided on end(s) of the flow-guiding rod. The coolant inlet pipe and the coolant outlet pipe are communicated with the cooling channel.

Apparatus and method of heating and ventilating an enclosed area comprising a floor arranged as a number of floor zones. The method comprises providing a radiant heater spaced above each floor zone so as in use to direct heat downwards towards the floor; providing a ventilating air inlet spaced above at least part of each floor zone, the air inlet being at the same level as, or closer to, the floor than the radiant heater, the air inlet being arranged in use to draw-in a controllable quantity of air from outside of the enclosed area; providing a ventilating air outlet spaced above at least part of each floor zone, the air outlet being spaced further from the floor than the radiant heater and air inlet, the air outlet being arranged in use to extract a controllable quantity of air from inside of the enclosed area, wherein the method further comprises, for each floor zone, independently controlling the quantity of air being drawn in and extracted from said floor zone based on the sensed temperature inside and outside the enclosed space.

Proposed is a heat dissipating device using turbulent flow. In the heat dissipating device, a plurality of block flow paths (12) are formed in parallel inside a block body (10), a first cap (16) and a second cap (28) are mounted on side surfaces (15) of the respective ends of the block body (10) so as to connect the block flow paths (12), a working fluid flows into the block flow paths (12), and the working fluid which has passed through the block flow paths (12) is transferred to the outside. Turbulence generators (38) are mounted inside the block flow paths (12), and finishing end portions (40) on the respective ends of the turbulence generators (38) are supported by the first cap (16) and the second cap (28) and are positioned inside the block flow paths (12).

A heat exchanger (100) includes a flow path layer (10) in which a first flow path (11) extending in a first direction and a second flow path (12) extending in a second direction are disposed in the same layer. In each of the first flow path and the second flow path, a flow path cross-sectional area is reduced and expanded along an extending direction of the flow path. The first flow path and the second flow path intersect each other in the same layer in first portions (23, 33) of which the flow path cross-sectional area is reduced, due to displacement of the first portions (23, 33) in a third direction.

A heat sink includes a main body and multiple circular pipes. The main body is in contact with at least one heat emitter. The circular pipes are disposed inside the main body. The circular pipes extend in a shape of helices and are configured to convey refrigerant. The circular pipes are arranged such that the central axes of the helices are adjacent. Each two of the circular pipes of which the central axes of the helices are adjacent to each other are intertwined with each other.
