[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] See also Figure 1-3 A sample storage device includes a urine storage test tube 1 and a test tube rack 2. The urine storage test tube 1 is inserted into the test tube rack 2. The urine storage test tube 1 includes a glass test tube 11 and a metal film 12. The metal film 12 is attached to the outer wall of the glass test tube 11. The design of the metal film 12 and the glass test tube 11 can quickly dissipate the urine temperature.

[0028] The test tube rack 2 includes a heat preservation box body 21 and a support plate 22, wherein the support plate 22 is arranged on the heat preservation box body 21, a semiconductor cooling sheet 23 is arranged on the inner cavity side wall of the heat preservation box body 21, and a round hole for placing the urine storage test tube 1 is opened on the support plate 22. The semiconductor cooling sheet 23 is used to cool the water in the heat preservation box body 21 to obtain ice water. The urine storage test tube 1 filled with urine is placed in the ice water, so that it can be stored for a longer time.

[0029] The metal film 12 is made of aluminum foil or copper foil, which has better thermal and cold conductivity and can quickly cool down the urine in the urine storage test tube 1 .

[0030] The heat preservation box body 21 includes a plastic box body 210 and a heat preservation layer 211. The heat preservation layer 211 is arranged on the outer wall of the plastic box body 210. The heat preservation layer 211 adopts heat preservation cotton or hard foam plastic board. The heat preservation box body 21 can keep the ice water warm to a certain extent, which is energy-saving and environmentally friendly.

[0031] A control box is provided on the outer wall of the heat preservation box body 21, and a controller is provided on the control box, and the controller is electrically connected to the semiconductor refrigeration sheet 23. The controller on the control box is used to control the operating power of the semiconductor refrigeration sheet 23, thereby realizing temperature control.

[0032] The outer wall of the metal film 12 is provided with bumps, which are made of aluminum or copper, and are arranged in an array on the outer wall of the metal film 12, and grooves are provided on the bumps. The design of the bumps greatly increases the contact area with ice water, thereby increasing heat conduction or cold conduction.

[0035] Working principle of this utility model:

[0036] When in use, first inject a proper amount of water into the heat preservation box body 21, and then adjust the controller. At this time, the semiconductor refrigeration sheet 23 starts to work, and the water in the heat preservation box body 21 cools down rapidly. Then the urine storage tube 1 filled with urine is placed on the bracket plate 22. The metal film 12 on the outside of the urine storage tube 1 contacts the ice water, and the urine inside it is cooled down rapidly, so it can be stored for a longer time.
