Field of the Invention The present invention relates to a liquid tank type thermal shock test apparatus for testing the characteristics of electric and electronic parts against thermal stress, and more particularly to a liquid tank of the apparatus which adheres to a sample basket or the like during a test operation. The present invention relates to a liquid tank type thermal shock test apparatus capable of recovering a heat medium liquid carried out.

験ができなくなることさえあった。By the way, during the test operation, when the sample basket is pulled up from the tank, the heat medium liquid in the tank is attached to the sample basket or the sample that has just been lifted, and this heat is transferred to the tank while the other tank is moving. There is a problem in that it drips down on the heat insulating portion that partitions between the heat insulating portion and the tank and contaminates the upper surface of the heat insulating portion, or flows in the heat insulating portion and then mixes into the other tank.
In particular, if it is a high-temperature heat medium liquid and flows into a low-temperature tank, the low-temperature heat medium liquid may be remarkably deteriorated, and even a normal test may not be performed.

In this method, a bat inclined toward the high-temperature tank is provided above both the low-temperature tank and the high-temperature tank, and the heat medium flowing down from the sample basket is received by the bat once regardless of whether it is for low-temperature or high-temperature use. The mixture of the two is poured into the liquid separators arranged side by side, and fractionated into the respective heat transfer fluids by utilizing the difference in boiling point between the heat transfer liquids. This is a collecting means that is returned to.

Flows into the high-temperature tank (3) along the inclination of the tank and is collected. Next, the sample basket (4) and the opening / closing lid (6) coming to the upper part of the low-temperature tank (2) are attached to the low-temperature tank (2).
Descend toward. At this time, the edge (19) of the opening / closing lid (6) is connected to the upper end (13) of the liquid collecting gutter (12).
Then, the liquid recovery gutter (12) is tilted toward the low temperature tank (2) in the opposite direction to the state shown in FIG.

ことができる。As described above, according to the present invention, a low-temperature tank and a high-temperature tank, each storing a heat medium liquid, are arranged at a required interval in the lower portion of the casing, and the sample basket hanging from the opening / closing lid is placed in the casing. For a low-temperature tank and a high-temperature tank, while alternately immersing, in a liquid tank type thermal shock test apparatus in which an opening / closing lid is covered at an upper opening of each tank, a liquid recovery gutter is provided on the upper surface of the intermediate heat insulating portion of both tanks. Both ends have a size substantially reaching the inner ends of the upper ends of the two tanks, and are arranged so as to be capable of alternately tilting by pressing the lid edge by lowering the open / close lid while supporting the middle part. Therefore, all of the heat transfer medium dripping from the sample basket or the like transferred from one tank to the other tank can be collected in each tank by the liquid collection gutter. For this reason, the heat medium liquids for the low temperature and the high temperature are not mixed with each other and the heat medium liquid does not deteriorate, and the thermal shock test can be continued without any inconvenience.
