An apparatus for disposing of organic or sewage sludge waste includes: a storage tank configured to collect and accommodate organic or sewage sludge waste; an agitator which is connected to the storage tank to decompose and dry the organic or sewage sludge waste supplied from the storage tank; a first deodorizer which is connected to one side of the agitator to biologically decompose and remove bad-odour substances from a waste gas generated during an agitating process of the organic or sewage sludge waste; a second deodorizer which heats and removes bad-odour substances contained in the waste gas from which the bad-odour substances have been partially removed by the first deodorizer; and a heat exchanger which heats the waste gas, which flows in the second deodorizer, through heat of the waste gas discharged from the second deodorizer.

A tube-in-tube heat exchanger utilizes a selectively permeable tube having a selective permeable layer to allow the refrigerant to transfer into an ionic liquid to generate heating or cooling. The ionic liquid then provides heating or cooling to a heat transfer fluid through a non-permeable layer or tube. The system may be configured as a shell and tube design, with the third fluid free to flow on the outside of the shell, or as a shell and tube-in-tube, with a central tube containing a first liquid, a second tube containing a second liquid, and an outer shell containing the third liquid. The selectively permeable tube may include an anion or cation selectively permeable layer and this layer may be supported by a support layer or tube.

A liquid cooling jacket includes a base portion and a protruding portion protruding from an end surface on a first side in a third direction of the base portion in the third direction. A heat dissipation assembly includes a recessed portion recessed from an end surface on a second side in the third direction. A refrigerant flow path having a width in the second direction is between the end surface on the first side in the third direction of the base portion and the end surface on the second side in the third direction of the heat dissipation assembly. A position of the recessed portion coincides with a position of the protruding portion. An end portion of the protruding portion is farther on the second side in the first direction than an end portion on the first side in the first direction of the recessed portion.

A heat exchange system includes a heat-absorbing substance such as Liquid Natural Gas (LNG), a heat dissipation apparatus, a water storage tank, a heat exchanger, and a heat exchanger. The heat exchanger is coupled between the LNG and the water storage tank. The heat exchanger is coupled between the heat dissipation apparatus and the water storage tank. The heat exchanger transfers heat of the heat dissipation apparatus to water of the water storage tank to lose heat to the heat exchanger, and the heat exchanger transfers heat of the water to the LNG.

A heat exchanger includes a plurality of tubes arranged in a juxtaposed configuration, and at least one first manifold member on the outside of the tubes. Each tube is wound to define a planar spiral, having a plurality of co-planar turns, and has an end portion, which extends starting from the inside of the corresponding planar spiral towards the outside thereof. The end portion is superimposed on the co-planar turns, in a position corresponding to a major face of the planar spiral, for connection to the manifold member. tube has a transverse depression defined in the co-planar turns at the major face of the planar spiral, and the transverse depression at least partially receives a a corresponding part of the end portion.

A heat exchange array arranged to be used in a heat exchange unit and further arranged to recover energy from an exhaust gas, comprising: a first heat exchange tube and a second heat exchange tube, each arranged to carry a heat exchange medium and further each comprising a series of external fins; and wherein the first heat exchange tube comprises a left-handed helically coiled tube having an first elastic stress, and the second heat exchange coil comprises a right-handed helically coiled tube having a second elastic stress, and wherein the first and second heat exchange tubes are interconnected such that the first elastic stress opposes the second elastic stress.

A gas furnace is provided. The gas furnace includes a combustion part in which a fuel gas is burnt to generate a combustion gas, a heat exchanger having a gas flow path through which the combustion gas flows, a blower configured to blow air around the heat exchanger, and an inducer configured to discharge the combustion gas from the heat exchanger. The heat exchanger includes at least one single path in which a single gas flow path is formed a single-multiple return bend configured to communicate with the single path and convert a flow direction of the combustion gas, and at least one multiple path having a plurality of paths that communicate with the single-multiple return bend and form multiple gas flow paths.
