DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. 1 and 2 relate to an embodiment of the contact type cooler of the present invention, FIG. 1 is an enlarged schematic perspective view of a cooler portion, and FIG. 2 is an overall sectional view.

This contact type cooler 10 is, for example, a sample 1
A cylindrical sample container 12 containing 1 is used as an object to be cooled, and is provided with a cooling member 13 in which a cylinder that can surround the outside of the sample container 12 is divided into two.

These cooling members 13 are hollow inside so as to cool the cooling fluid while supplying the cooling fluid from one end and discharging the cooling fluid from the other end. It is configured so that it can be cooled.

The contact-type cooler 10 is provided with a moving mechanism 14, and the cooling member 13 is connected to the sample container 12.
It can be moved to both sides of.

When these two cooling members 13 are combined, a space corresponding to the cylindrical sample container 12 is formed at the center, and each of the cooling members 13 has a semicircular cross section. A cushioning member 15 planted in a brush shape using carbon fibers is provided inside, and the radius of the inner portion of the cooling member 13 is increased by the length of the cushioning member (carbon fibers) 15.

Moving mechanism 1 for moving these cooling members 13
As shown in FIG. 2, a feed screw 17 is rotatably supported on the upper part of the experimental device 16 on which the sample container 12 is supported, in the cross-sectional direction of the sample container 12, and the reverse screws are provided on both sides from the center. Is formed.

Then, nuts 18 and 19 are respectively screwed into the two screw portions of the feed screw 17, and the cooling member 13 is attached to the nuts 18 and 19 via arms 20 and 21, respectively. 20, 2
1 is guided so that it does not rotate but only moves laterally.

The feed screw 17 is driven by a motor or the like (not shown). In the contact-type cooler 10 configured as described above, when the sample 11 needs to be rapidly cooled, when the feed screw 17 is rotated by a motor or the like (not shown), the nuts 18 and 19 are moved to approach each other, and the nut 18 is moved. , 19 are attached to the sample container 12 via arms 20 and 21 from both sides of the sample container 12.

Then, when the cooling member 13 approaches the sample container 12, the approaching speed is reduced to bring the cooling member 13 closer to the sample container 12 at a very low speed to bring the buffer member 15 into contact with the sample container 12 and stop it.

As a result, the cooling member 13 does not come into direct contact with the sample container 12, but the brush-like cushioning member 15 made of carbon fibers planted in the cooling member 12 comes into contact with the sample container 12, so that the carbon fiber The flexibility of allows absorbing the impact at the time of contact, and suppressing the impact load at the time of contact as much as possible.

Further, when cooling, the carbon fiber buffer member 15 is located between the cooling member 13 and the sample container 12. However, since the thermal conductivity of carbon fiber is almost the same as that of metal, it depends on the carbon fiber. By implanting the cushioning member 15 with a certain density, it is possible to efficiently perform rapid cooling by heat conduction.

Therefore, it is possible to make the impact load at the time of contact as small as possible and to improve the cooling efficiency due to the contact, and to use it as it is for conducting material experiments without adversely affecting the microgravity environment in space. be able to.

In the above embodiment, the case where carbon fiber is used as the heat-resistant and flexible fiber has been described, but not limited to this, Teflon or the like may be used. However, the carbon fiber is particularly heat-resistant. It is also preferable because it has excellent thermal conductivity.

Although the cooler is composed of the cooling members divided into two parts, the cooler is not limited to this, and the cooler may have an integral structure or another structure.

Further, the present invention is not limited to the above-mentioned embodiments, and each constituent element may be modified within a range not changing the gist of the present invention.

[0029]

According to the contact type cooler of the present invention as specifically described above with reference to the embodiment, the contact surface of the cooler with the object to be cooled (such as the sample contained in the sample container) is Since a heat-resistant and flexible fiber is planted to provide a cushioning member in the form of a brush, the flexibility of this fiber minimizes the impact load at the time of contact with the object to be cooled, and its high thermal conductivity. Depending on the size, it can be cooled rapidly.

This makes it possible to carry out material experiments without adversely affecting the microgravity environment in space.
