Specific embodiment
For convenient for those skilled in the art understand that technical solutions of the utility model, practical new to this now in conjunction with Figure of description
Type technical solution is described further.
As shown in Figures 1 and 2, present embodiment discloses a kind of capillary heating element for XRD and XAS test,
For capillary as liquid reactive sample cell, and while acquiring XRD, XAS signal, is heated.The heating element includes two
1, interconnecting piece 2 of calandria and a temperature measuring equipment 3.
The calandria 1 includes core 11, shell 12 and heater strip 13.
The core 11 is in the form of a column, and is formed with capillary channel 14 thereon；The shell 12 is wrapped on core 11, and
Cavity (being not marked in figure) is formed between shell 12 and core 11, the heater strip 13 is arranged in cavity.Preferably, in this reality
It applies in example, core 11 and shell 12 are in cylindrical body, and capillary channel 14, core 11, shell 12 are coaxially disposed；Heater strip 13
It for armouring heater strip, and is wrapped on the core 11, such heater strip 13 is insulated contact with core 11, it is ensured that is used
Safety.
The coaxial arrangement of calandria 1 described in two, and connected by interconnecting piece 2.The both ends of the interconnecting piece 2 are respectively with two
The opposite end face connection of a calandria 1, forms a window 4, which is to constitute X-ray between interconnecting piece 2 and calandria 1
Through channel.
In more detail, refering to Fig. 3, along the axis direction of core 1, the interconnecting piece 2 is fan-shaped, cambered surface and calandria
1 lateral surface flushes, and the angle of the sector adjusts within the scope of 80-100 °, and the angle in the present embodiment is set as 90 °.Window 4
Setting the purpose of be to make X-ray transparent, additionally need in view of in capillary fluid temperature it is uniform, therefore in design ruler
On very little, under the premise of ensuring X-ray transparent, the size of window 4 is the smaller the better, that is, in the case where guaranteeing that X-ray passes through,
The length of interconnecting piece 2 is the smaller the better, for example, in the present embodiment, the length of calandria is 35mm, and the length of interconnecting piece 2 is
5mm。
The temperature measuring equipment 3 is to detect heating temperature, and temperature measuring equipment 3 can choose thermal resistance or thermocouple, in this reality
