Fig. 2 is the overlooking the structure diagram of the present invention.
Fig. 3 is A-A in Fig. 1 to structural representation.
Fig. 4 is the test mode schematic diagram of the present invention.
Embodiment
Below in conjunction with embodiment shown in the drawings, the invention will be further described；But the invention is not limited in following reality
Apply example.
The heat load adjusting device of efficiency test shown in the drawings of being shaped suitable for boiler of organic heat carrier, is typically mounted on
On return line before the circulating pump of boiler of organic heat carrier.
In the adjusting means：Casing 15 is a thin-walled pressure vessel, for holding coolant (generally optional horizontal plane projection
For the metal cabinet of rectangle, preferably steel plate makes)；One organic heat carrier heat exchange tube panel (the following letter of cabinets cavity horizontal positioned
Claim heat exchange tube panel), or it is horizontally disposed and neatly stack several interconnected heat exchange tube panels up and down, and each exchange heat tube panel
Include being parallel to each other and the import header 1 and outlet header 3 of arrangement spaced apart and being arranged parallel to and two ends
It is respectively communicated with several heat exchanger tubes 2 of import header and outlet header；The specification of heat exchanger tube can determine (preferred diameter as needed
For 76mm steel pipe)；Tank walls are installed with one group of connection cabinets cavity or some groups of coolants import and export adapter (as excellent
Choosing, cooling liquid inlet adapter 8 is arranged on casing top, and cooling liquid outlet adapter 5 is arranged on bottom half)；On heat exchange tube panel also
It is respectively arranged with the organic heat carrier flowline 10 extended to outside casing and (specifically connects the heat exchange tube panel positioned at casing top
Outlet header) with organic heat carrier oil inlet pipe 12 (specifically connect positioned at bottom half heat exchange tube panel bottom inlet collection
On case 1-1).
Further, it (is fin heat exchange tube that fin can be provided with described heat exchanger tube；Fin heat exchange tube is tied to be conventional
Structure, Gu Tuzhong is omitted), to significantly improve heat transfer effect.
When several described heat exchange tube panels are interconnected, the top welding in advance of the outlet header in each heat exchange tube panel is simultaneously
Connecting tube 6 (2 are shown in Fig. 2) is connected, the top of import header is then welded supporting plate 7 (2 are shown in Fig. 2)；It is multiple
When heat exchange tube panel is stacked, heat exchange tube panel above is laminated on the heat exchange tube panel of lower section；Wherein, the outlet header of top is put
In the import header for being placed on lower section, the import header of top is placed in the connecting tube of the outlet header of lower section and in corresponding site
With connecting tube welding conducting after perforate (flow direction for the organic heat carrier being consequently formed is as shown by the arrows in Figure 1).Supporting plate
Height should be adapted with the height of connecting tube, so as to can keep overall smooth during multiple heat exchange tube panel mounted on top.In addition,
The spacing between two supporting plates on same heat exchange tube panel is recommended as 100mm, also helps lifting work during installation.
The bottom half is provided with coolant sewage component 13 (preferably DN40 sewage draining valve).
In addition, the heat exchange tube panel positioned at adjusting means bottom is additionally provided with part 12 of draining the oil (preferred DN40 valve；Specifically set
Put on bottom inlet header 1-1 and outlet at bottom header 3-1)；Heat exchange tube panel at the top of adjusting means is provided with exhaust portion
