Abstract:
A heat exchanger for fluids is disclosed. The heat exchanger comprises a vessel with an inner space for containing a refrigerant. The inner space is bounded by an inner surface of a first vessel wall, and the vessel comprises an inlet and an outlet for transport of a refrigerant into and out of the inner space. At least one tube has at least one first tube portion inside the inner space. A first end of the first tube portion is fixed to a first orifice of the vessel and a second end of the first tube portion is fixed to a second orifice of the vessel to enable fluid communication into and/or out of the first tube portion through the first orifice and the second orifice. A chamber outside the inner space is arranged to enable heat exchange between fluid inside the chamber and the refrigerant inside the inner space.
Abstract:
The present invention relates to a system (1) for recovering heat from the hot effluent flow flowing out from industrial machines (M) preferably used for textile processing, which allows to manage in a unitary and efficient manner, and in particular with a single exchanger (2), the regulation the flow incoming to the machines (2), as a function of the previous energy exchange between such inlet flow and such outlet flow.
Abstract:
초음파 진동 발생부의 주변온도를 냉각하여 초음파 진동 발생부가 고온에 노출되는 환경에서도 초음파 진동 발생부의 온도를 일정하게 유지할 수 있는 초음파 분무장치를 제공한다. 초음파 분무장치는 초음파를 발생하고 분사재를 무화시키는 초음파 진동 발생부, 초음파 진동 발생부의 중심을 관통하는 중심축을 따라 분사재가 이동하는 분사유로를 포함하고, 분사유로의 일측단으로부터 분사재를 공급받고 분사유로의 타측단에는 분사재를 분사하는 노즐팁을 포함하는 노즐부, 초음파 진동 발생부를 둘러싸고 있고, 내부에 복수의 열교환실을 갖는 하우징, 그리고 초음파 진동 발생부를 둘러싸고 있고, 복수의 열교환실을 구분하는 분리벽을 포함하고, 초음파 진동 발생부로부터 발생된 열을 냉각하는 열교환부를 포함하며, 복수의 열교환실은 하우징 내부에서 초음파 진동 발생부의 주변에 위치하고 발열공간을 포함하는 발열실, 그리고 발열실을 둘러싸고 있으며 발열실과 접하는 열교환부를 사이에 두고 격리되어 냉각공간을 포함하는 냉각실을 포함한다.
Abstract:
The invention relates to a steam generator (1) for a Rankine process, in particular for a waste-heat utilization device (37) of an internal combustion engine (36), preferably in a motor vehicle, comprising: a heat exchanger duct (2) in which a heat exchanger (3) is arranged, and a bypass duct (4) for bypassing the heat exchanger duct (2), wherein the heat exchanger duct (2) and the bypass duct (4) can, during operation of the steam generator (1), be traversed by a flow of a heating fluid, and wherein the heat exchanger (3) can, during operation of the steam generator (1), be traversed by a flow of a medium (47) to be evaporated. A compact design with high energy efficiency can be attained if the heat exchanger duct (2) encases the bypass duct (4).
Abstract:
A shell and tube heat exchanger arrangement comprising at least two interconnected heater cells (30), the heater cells (30) each in turn comprising a plurality of inner tubes (36) defining a tube side of the heat exchanger and being housed within an outer shell (34) defining a shell side of the heat exchanger, characterised in that the inner tubes (36) each project beyond the outer shell (34) at one end thereof at which point they are each connected to an intermediate pipe member (44) by way of which that heater cell (30) may be connected to another heater cell.
