Title:
DEVICE FOR VARYING COEFFICIENT OF OVERALL HEAT TRANSMISSION
Document Type and Number:
Japanese Patent JPS59229196
Kind Code:
A
Abstract:

PURPOSE: To make available the varying of coefficient of overall heat transmission uniformly and simply with excellent reproducibility, by arranging the wall body structure of laboratory wherein the coefficient of overall heat transmission is tested such that the wall body structure is divided into a plurality of layers and a liquid is charged to every one of layers.

CONSTITUTION: Cellular members 2aW2d are pinched by a partition board 3, frame bodies 4aW4d, a side plate 5 and a packing 6 and clamped in place by a bolt 7 for forming clearance layers 8aW8d. The clearance layers 8aW8d are provided with channels 9aW9d for filling and draining a liquid, and channels 10aW 10d for venting an air in pouring a liquid and for withdrawing an air in draining the liquid. Thus, the various coefficients of overall heat transmission may be obtained by combining any of clearance layers 8aW8d in their state wherein the liquid is poured or clearances are left as they are.
