    • Waste water heat transfer apparatus (10) is disclosed in which the waste hot water from residential or commercial uses such as washing, etc., is passed into a separate drain (24) and then into a heat exchanger (17) which includes a waste water conduit (40) therein, and then to the sewer drain (29). A supply water conduit (70) extends through the heat exchanger (11) generally paralleling the waste water conduit (40) and has fresh water run therethrough in a direction opposite to that of the flow of waste water to an outlet end, after which the supply water is provided to a water heater (20). The heat exchanger interior is filled with a heat transfer liquid (39), and is so divided by baffles (75, 76) that a temperature gradient is formed in the heat transfer liquid adjacent to the waste water conduit (40), with the liquid being warmest adjacent the inlet (68) of the waste water conduit and decreasing in temperature toward the outlet (69) of the conduit. The supply water, flowing in the opposite direction to that of the waste water, has its lowest temperature at its inlet end (71), which is adjacent the lowest temperature heat transfer liquid, and encounters progressively warmer adjacent heat transfer liquid as it rises upwardly in the heat exchanger toward its outlet end (72). A substantially constant temperature differential is therby maintained throughout the heat exchanger between the waste water within the waste water conduit and the adjacent heat transfer liquid, and between the supply water in the supply water conduit and the adjacent heat transfer liquid. The transfer of a portion of the heat contained in the waste water to the supply water reduces the amount of energy that must be consumed by the water heater, and the system may also be tied to a hot water space heater (45) for a home or other building to preheat the water supplied to the boiler and thereby reduce the energy demand for space heating purposes.

    • A heat exchanger has a multiplicity of modules with an outer shell which is open at the top and the bottom and is joined with other modules in a stacked array. The heat exchanger has an insulating partition which is attached to the inside surface of the shell and divides the shell into two or more flow channels. The insulating partition has a hole which connects the flow channels defined by the shell and baffle. The hole is occupied by a heat-conductive heat storage reservoir, so that heat flow from one channel to another is through the heat storage reservoir. In this way, heat may pass from one flow channel into the storage reservoir and at a latter time be exchanged with a fluid flowing in another flow channel. Heat exchange modules have multiple flow channels and the flow channels preferably have heat conducting fins for increasing the heat transfer between the flow channels and the heat storage reservoir.
    • 热交换器具有多个具有外壳的模块,外壳在顶部和底部是开放的,并且与堆叠的阵列中的其它模块连接。 热交换器具有绝缘隔板,该绝缘隔板连接到外壳的内表面,并将外壳分成两个或更多个流动通道。 绝缘隔板具有连接由壳和挡板限定的流动通道的孔。 该孔由导热储热容器占据,从而从一个通道到另一个通道的热流通过储热容器。 以这种方式,热可以从一个流动通道进入储存容器,并且在稍后的时间可以与在另一个流动通道中流动的流体交换。 热交换模块具有多个流动通道,并且流动通道优选地具有用于增加流动通道和储热容器之间的热传递的导热翅片。

    • 公开了一种废水传热装置,其中来自住宅或商业用途的诸如洗涤等的废水进入单独的排水管,然后进入包括其中的废水管道的热交换器,然后到排水管 。 供水管道延伸穿过通常与废水管道平行的热交换器,并且将淡水以与废水流相反的方向流过其中,然后将供水提供给热水器。 热交换器内部填充有传热液体,并且被与在废水管道附近的传热液体中形成温度梯度的挡板相分离,液体在废水管道的入口附近是最热的, 导管的出口温度降低。 以与废水相反的方向流动的供水在其入口端具有最低的温度,其与最低温度的传热液体相邻,并且在热量向上升高时遇到逐渐变暖的相邻传热液体 交换器朝向其出口端。 因此,在废水管道内的废水和相邻的传热液体之间以及供水管道中的供水和相邻的传热液体之间的整个热交换器中保持基本恒定的温度差。
