Title: Heat exchanger
Inventor: YAMAMOTO YOSHIAKI
IPC: F28D9/00
Filed: 1984-11-09
Abstract: PURPOSE:To increase the heat transfer coefficient of fluid, eliminate ununiformity of flow amount due to branching and improve the heat transfer performance. CONSTITUTION:Spacer members 21, 23, 25 and fin members 14, 16, 18 are laminated alternately to form the heat exchanger. The fluid T flows into the heat exchanger from the downstream side of the fluid U, branched in a header, effects heat exchange between the fluid U in zigzag flow paths and is collected in the header at the upstream side of the fluid U, thereafter, flows out of the heat exchanger. One flow path is formed by 5 sheets of fin members in this example, however, the number of sheet may be changed in accordance with the flow amount, physical properties and the like of the fluid T. As a result, the number of branch of the fluid T is reduced to 1/5. Accordingly the flow amount per one flow path is increased in accordance with the decrease of the number of branch and whereby the heat transfer coefficient may be increased. On the other hand, the flow amount per one flow path becomes more uniform since the number of branch is decreased.

Abstract: PURPOSE:To enable reliable measurement of the position of a liquid level irrespective of the kind of a liquid filled up in a vessel, by forming a reflected light image of the liquid level by applying a light thereto obliquely from below, and by calculating the position of the liquid level from the reflected light image. CONSTITUTION:When a light is applied from a light projecting element 14 onto the surface of a liquid filled up in a light-transmitting vessel, obliquely from below, it is reflected regularly by the surface of the liquid and reaches an image-sensing element 15. When this reflected light is sensed, a reflected light image wherein the part of the liquid surface is brilliant in high luminance is obtained and the position of the liquid surface is calculated from the part of high luminance by a control processing element 17. When the liquid filled up in a mixture having a property of separating vertically, the light is applied to a position being higher than the level of a lower-layer liquid, by an upper- layer liquid detecting sensor 16. Then the direction of refraction of the light differs according to the presence or absence of the upper-layer liquid, and by observing a transmitted light at an appropriate place, the presence or absence of the upper-layer liquid can be known.
