Cooling device

Abstract

The present invention relates to a cooling device, mainly comprises a carrying unit, a thermal insulation unit, and a temperature-lowering module. The thermal insulation unit is provided over a part of surface of the carrying unit for blocking heat transmission between the carrying unit and the outside. As the carrying unit is placed on the temperature-lowering module, a cooling chip in the temperature-lowering module is able to lower the temperature of the carrying unit and a biological sample. Furthermore, the thermal insulation unit is able to maintain the temperature of the carrying unit and biological sample, when the carrying unit is removed from the temperature-lowering module. Thereafter, a user can conveniently practice observation and experiment with respect to the biological sample, and avoid damaging the biological sample during experiment or transportation by the use of the cooling device.

Description

FIELD OF THE INVENTION[0001]The present invention is related to a cooling device for maintaining the temperature of a biological sample on a carrying unit in a certain range and facilitating a user to observe or transport the biological sample.BACKGROUND[0002]Biological samples prepared in biological laboratories generally include enzymes, anti bodies and added reactants, and should be preserved in a certain range of temperature without being damaged. For instance, the tissue or the activity of enzyme of a biological sample may be damaged if the biological sample freezes, while the reaction may occur early or enzyme may become inactive if a biological sample is subjected to a higher temperature (room temperature) for a long period of time.[0003]In a laboratory, it is common to pour the prepared biological sample into test tubes (or known as micro centrifugal tubes), and preserve this biological sample by means of ice block made by an ice machine, for the further observation or exper...

Benefits of technology

[0007]It is one object of the present invention to provide a cooling device, allowed for maintaining the temperature of a biological sample on a carrying unit in a certain range for a long period of time. A temperature-lowering module can be applied for controlling the temperature of the biological sample to facilitate the experiment or observation with respect to the biological sample.

[0008]It is a further object of the present invention to provide a cooling device, in which a carrying unit and / or the thermal insulation unit may be either placed on or separated from the temperature-lowering module. A user is allowed to remove one carrying unit from and then place another one onto the temperature-lowering module during experiment, thus enhancing convenience of operation.

[0010]It is a further object of the present invention to provide a cooling device, which comprises fins for drawing heat generated by a cooling chip. The cooling device further comprises at least one fan additionally provided on the casing for drawing heat within a casing via heat convection and enhancing performance of the cooling chip.

[0011]It is a further object of the present invention to provide a cooling device, which comprises a cooling chip for lowering the temperature of the biological sample, maintaining the temperature of a biological sample in a certain range in the process of experiment, and further eliminating trouble due to the use of ice bucket and ice block. Thus, not only keeping an eye on the temperature of biological sample and ice bucket at any time in the process of experiment is not necessary, but also the contamination to the biological sample due to ice block or ice water is effectively prevented.

[0012]It is a further object of the present invention to provide a cooling device, which comprises a cooling chip instead of ice blocks and ice bucket to preserve a biological sample in the process of experiment primarily for eliminating trouble in making ice and reducing energy wastage for the purpose of environmental protection.

Problems solved by technology

For instance, the tissue or the activity of enzyme of a biological sample may be damaged if the biological sample freezes, while the reaction may occur early or enzyme may become inactive if a biological sample is subjected to a higher temperature (room temperature) for a long period of time.

The temperature within the ice bucket may rise, however, in the condition of ice / water coexistence formed due to the gradual melting of ice blocks situated in the environment at room temperature for a long period of time.

The possible temperature rise of the biological sample may occur, further resulting in an experimental error or damage to the biological sample, if the user neglects the temperature rise of the interior of the ice bucket or forgets the addition of ice blocks.

In the condition of ice / water coexistence within the ice bucket, the test tubes may sink or float in ice water, harmful to observation.

Moreover, the tube mouth of the test tube or micro centrifugal tube may touch ice water inside the ice bucket, leading to contamination to the biological sample within the test tube when the ice water at the tube mouth flows into the biological sample.

If the observation of biological sample is performed in the aforementioned way, trouble in performing an experiment may be caused for the user, and additionally, the probability of experimental failure caused by contamination to the biological sample may be also increased undoubtedly.
