Preferably, in this embodiment, can dismantle between the straight plate section 5 that the arc plate section 6 and correspond and be connected, can in time change this part structure when certain part of fixed plate takes place to damage on the one hand, and need not change whole fixed plate, reduce the replacement cost, on the other hand also can select suitable arc plate section as required to can simulate the radial heat exchanger test of different air inlet circle, improved this heat exchanger test fixing device's suitability.
Preferably, the arc plate sections 6 are inserted or clamped with the corresponding straight plate sections 5, so that the connection structure of the arc plate sections 6 and the straight plate sections 5 can be simplified, the installation and disassembly difficulty is reduced, and the assembly and disassembly efficiency is improved. Of course, the arc plate section 6 and the corresponding straight plate section 5 can be detachably connected in other ways.
In order to further improve the universality of the heat exchanger test fixing device, the heat exchanger test fixing device needs to be adjusted to different frame shapes and air inlet radians according to the test requirements, so that one heat exchanger test fixing device can process a plurality of modules, and the modules can be combined as required, so that the heat exchanger test fixing device can be suitable for the test fixation of heat exchangers of various specifications, the utilization rate of each component is improved, and the test requirements of heat exchangers of various specifications are met.
Specifically, such a structural module may take the following various forms.
For example, the plurality of straight plate sections 5 may have different lengths, the plurality of arc plate sections 6 may have a plurality of different lengths and different arcs, and the straight plate sections 5 and the arc plate sections 6 having matching lengths may be arbitrarily combined. In this case, the arc plate section 6 may be an integral structure, and the straight plate section 5 may be an integral structure, wherein the plurality of arc plate sections 6 may form an arc plate section group, and the arc plate section group may include arc plate sections having the same length but different radians, or may include a plurality of arc plate sections having the same radians but different lengths. The plurality of straight plate segments 5 may form a straight plate segment group, and the straight plate segment group includes a plurality of straight plate segments with different lengths. The straight plate section 5 and the arc plate section 6 with the same length can be combined at will, so that a plurality of heat exchanger testing fixing devices with different air inlet ring radiuses are formed.
In another embodiment, the arc plate segment 6 comprises a plurality of middle segments 7 and a plurality of corner segments 8, the middle segments 7 have different lengths and different radians, the corner segments 8 have different lengths and different radians, and the middle segments 7 and the corner segments 8 with the same radians can be combined arbitrarily. In this embodiment, the arc plate sections 6 are split into more and smaller units, so that more refined module combination can be realized, the fixed requirements of heat exchangers with more different specifications can be met, the maintenance or replacement cost can be further reduced, and the combination selectivity can be improved.
In another embodiment, each of the first fixing plate 1, the second fixing plate 2, the third fixing plate 3 and/or the fourth fixing plate 4 is integrally formed, and the plurality of first fixing plates 1, second fixing plates 2, third fixing plates 3 and/or fourth fixing plates 4 have different lengths. In this embodiment, only the first fixing plate 1, the second fixing plate 2, the third fixing plate 3 and the fourth fixing plate 4 of different specifications need to be selected, so that the heat exchanger testing fixing device of different specifications can be formed, and actual testing requirements are met. The fixing plates can have the same radian, and the testing requirements of heat exchangers with different specifications under the condition of the same radius of the air inlet ring can be tested. The difference here means that the lengths of the first fixing plates of the same module group are different, the lengths of the second fixing plates of the same module group are different, the lengths of the third fixing plates of the same module group are different, and the lengths of the fourth fixing plates of the same module group are different, and the different fixing plates are not limited. Generally, the first fixing plate 1 and the second fixing plate 2 should have the same specification, and the third fixing plate 3 and the fourth fixing plate 4 should have the same specification.
Further, the arc plate segments 6 of the plurality of first fixing plates 1, second fixing plates 2, third fixing plates 3 and/or fourth fixing plates 4 have different arcs. At this time, the plurality of first fixing plates 1 may have different curvatures, or different curvatures and lengths, and the other fixing plates have similar characteristics. Under the condition, the fixing plates are combined, so that the testing requirements of different air inlet ring radiuses of different heat exchangers can be met.

Preferably, the widths of the first and second fixing plates 1 and 2 are greater than the widths of the third and fourth fixing plates 3 and 4. Since two of the opposite sides of the heat exchanger 9 have connection pipes, this needs to be taken into account when designing the heat exchanger test fixture. The widths of the first fixing plate 1 and the second fixing plate 2 are larger than the widths of the third fixing plate 3 and the fourth fixing plate 4, so that two sides of the heat exchanger without connecting pipes can be fixed through the straight plate sections 5 of the first fixing plate 1 and the second fixing plate 2, sufficient contact length between the heat exchanger 9 and the straight plate sections 5 of the first fixing plate 1 and the second fixing plate 2 is ensured, and the heat exchanger 9 can be stably and reliably installed and positioned. To the both sides of the heat exchanger 9 that have the connecting pipe, because the straight plate section 5 width of third fixed plate 3 and fourth fixed plate 4 is less, consequently can leave great dodge the space, come the holding connecting pipe, avoid the straight plate section 5 of third fixed plate 3 and fourth fixed plate 4 to form the interference to the connecting pipe, guarantee that the heat exchanger 9 can install smoothly and fix on heat exchanger test fixing device.
The purpose of arranging the straight plate sections 5 on the third fixing plate 3 and the fourth fixing plate 4 is to connect and fix the wider straight plate sections 5 on the first fixing plate 1 and the second fixing plate 2 through the two narrower straight plate sections 5, so that the overall structural strength of the heat exchanger testing and fixing device is improved, and the heat exchanger 9 is guaranteed to be stably and reliably mounted and fixed.
It is to be understood that the present invention is not limited to the procedures and structures described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof. The scope of the invention is limited only by the appended claims.
