摘要： A grey water heat recovery apparatus is disclosed in which heat is transferred between a grey water stream and a fresh water stream. The apparatus comprises: a grey water flow path leading from a source inlet to a drain outlet; a plurality of heat exchangers arranged in said grey water flow path; a separator arranged upstream of said heat exchangers, arranged to separate grey water from the source inlet into a plurality of parallel sub-paths, each sub-path being lead to one of the heat exchangers; and a collector arranged downstream of said heat exchangers, arranged to reassemble the grey water from the sub-paths into a single flow path. Each heat exchanger comprises a grey water tube extending from the separator to the collector, and an outer tube surrounding at least a part of the grey water tube, the outer tube defining an annular space around the grey water tube. A fresh water flow path formed within the annular spaces around the grey water tubes in the heat exchangers has a flow direction being opposite to the flow direction of the grey water.

摘要： A cooling apparatus is disclosed. The cooling apparatus comprises a housing, a first liquid and a second liquid located within the housing. The first liquid has a higher density and lower boiling point than the second liquid. The cooling apparatus further comprises a heat exchanging apparatus to transfer heat to the first liquid to evaporate the first liquid to form a first liquid vapour. The cooling apparatus also comprises a plurality of independent energy dissipating members that extend through the housing. These members move in response to a fluid flow created by the interaction of the first liquid vapour and the second liquid and transfer heat to a volume external to the housing. The cooling apparatus can cool a body whilst drawing minimal or even no electrical power. As such the cooling apparatus is environmentally friendly and cheaper to operate.

摘要： 본 발명에 따른 이중 파이프는 외주면에 요철이 형성된 외측 파이프와, 내주면에 요철이 형성되어 있고 상기 외측 파이프에 삽입된 내측 파이프를 포함한다. 본 발명에 따른 이중 파이프는 외주면에 나선형 요철(Groove and Ridge)이 형성된 내측 파이프와 내주면에 나선형 요철이 형성된 외측 파이프가 나사 결합 되어 있다. 내측 파이프의 내부로는 저압 냉매가 통과된다. 내측 파이프의 외주면과 내측 파이프의 외주면 사이의 공간으로 고압 냉매의 통로를 확보하기 위하여, 내측 파이프의 외주면에 형성된 나선형 요철의 일부는 다중 나선형 요철로 구성하고, 이와 나사 결합되는 외측 파이프의 내주면에 형성된 나선형 요철의 일부는 단일 나선형 요철(정확하게는 내측 파이프의 다중 나선형 요철의 줄 수보다 적은 수의 나선형 요철)로 구성한다. 즉, 내측 파이프의 외주면에 형성된 다중 나선형 요철 중 나사 결합 되지 않는 나선형 요철의 요부(Groove)와 외측 파이프 사이의 공간으로 고압의 냉매가 흐르도록 구성된다.

摘要： A heat exchanger (4) has fluid flow channels (6) with at least one heat exchanging surface (10) which has an undulating surface section for which the surface profile varies along a predetermined direction such that at a first edge (E1) the surface profile follows a first transverse wave (20), at a second edge (E)2 the surface profile follows a second transverse wave (22) and at an intermediate point I between the edges the surface profile follows a third transverse wave (24). The third transverse wave (24) has a different phase, frequency or amplitude to the first and second transverse waves so that chevron-shaped ridges and valleys are formed. This improves the mixing of fluid passing through the channel and hence the heat exchange efficiency.

摘要： The present invention refers to a heat transfer unit (6A) for transferring heat from a heated gas to a liquid in particular to water, wherein the heat transfer unit in particular is for a heating apparatus (1) for a recreational vehicle. The heat transfer unit (6A) comprises a gas conduit (60A) configured to receive and transfer the heated gas and a heat transfer tank (504A) configured to contain the liquid. The gas conduit (60A) has a gas inlet (603A), a gas outlet (604A) as well as a first heat transfer zone (601A) surrounded by a corresponding chamber and a second heat transfer zone (602A) surrounded by a corresponding gas pipe. The chamber surrounding the first heat transfer zone (601A) is coupled to the gas inlet (603A), the gas pipe surrounding the second heat transfer zone (602A) is coupled to the chamber surrounding the first heat transfer zone (601A) and the gas outlet (604A) is coupled to the gas pipe surrounding the second heat transfer zone (602A). The gas conduit (60A) is geometrically shaped in such a way that due to convection, heated gas entering the gas conduit (60A) at the gas inlet (603A) at first has to flow through the first heat transfer zone (601A) and then through the second heat transfer zone (602A) before it can leave the gas conduit (60A) through the gas outlet (604A). The chamber surrounding the first heat transfer zone (601A) and the gas pipe surrounding the second heat transfer zone (602A) are provided within the heat transfer tank (504A). The chamber surrounding the first heat transfer zone (601A) is provided as triangular chamber and the gas pipe surrounding the second heat transfer zone (602A) is coupled to the triangular chamber surrounding the first heat transfer zone (601A) in the area of one of its corners. Moreover, the present invention refers to a heating unit, a heating apparatus and a recreational vehicle provided with such a heat transfer unit.
