Abstract
The utility model relates to an automatic ice-embedding freezer for living organisms, which solves the problem of man-power ice embedding or automatic ice embedding of a self-control mechanical device existing in the process of freezing living organisms. The utility model is mainly characterized in that a lower part relative high-temperature zone and an upper part relative low-temperature zone are formed in a chamber of the utility model or between the utility model and upper environment so that the utility model realizes automatic ice embedding, largely reduces cost, can completely eliminate the super-cooling phenomenon before icing and effectively enhance a freezing effect, and therefore, the utility model is an ideal freezing device for living organisms.
Description
Device, especially the biological living auto ice-embedding freezer unit of live bodies such as a kind of freezing biological cell, tissue, embryo.
Present biological living frigorimeter, what have still need be with artificial " planting ice ".All realizing of auto ice-embedding by mechanical action and control system thereof.Their common characteristic be before all eliminate freezing fully " cold excessively " phenomenon and to the harm of live body.
The purpose of this utility model is: neither use artificial " planting ice ", again not by the automatic control mechanical action, but realize automatically " planting ice " by the structure of freezer unit, reduce cost greatly, and can eliminate " cold excessively " phenomenon fully, improve refrigerating effect.
The utility model technical solution is; utilize the structure of freezer unit; make the container of depositing live body have the bottom of live body to place relatively-high temperature district, bottom, make no live body have only the top of protection liquid to place the relative low-temperature space in top, reach the top purpose of " planting ice " automatically.
Realize the biological living auto ice-embedding freezer unit of such scheme, its structure has two kinds:
First kind is: a metal cylinder (groove) that liquid is housed is arranged in bottom relatively-high temperature district.
Second kind is: there are several metal tubes in the district at the bottom relatively-high temperature.
In order to guarantee the temperature difference of relatively-high temperature district, bottom and the relative low-temperature space in top, be tied with resistance wire as thermal source at relatively-high temperature district, the bottom metal cylinder (groove) of above-mentioned two kinds of biological living auto ice-embedding freezer units or the outer wall that is arranged in several metal tubes of annular.Between bottom relatively-high temperature district metal cylinder (groove) or pipe and shell, filling is with heat-barrier material in the metal tube annular and between each metal tube.The relative low-temperature space in top has lagging casing or does not have shell.
In order to control the variations in temperature of bottom effectively, in bottom relatively-high temperature district metal cylinder (groove) or several metal tube outer walls a temperature-sensitive original paper is set simultaneously, make it and electronic computer and resistance wire form the closed-loop control link.
Because the temperature-sensitive original paper is closely contacted with low-temperature receiver with bottom relatively-high temperature district metal cylinder (groove) or pipe resistance wire outward, guaranteed the sensitivity of temperature-sensitive temperature control, guaranteed refrigerating effect.
The utility model advantage:
1, saves artificial " planting ice " step, and removed used mechanical device and the robot control system(RCS) thereof of auto ice-embedding from, greatly reduced cost, and can eliminate " cold excessively " phenomenon fully, improved refrigerating effect.
2, utilize the temperature-sensitive original paper to contact, guaranteed the sensitivity of temperature-sensitive temperature control, guaranteed refrigerating effect with metal cylinder (groove) or pipe resistance wire and the tight of low-temperature receiver outward.
Below in conjunction with description of drawings the utility model most preferred embodiment.
Fig. 1 is relatively-high temperature district, bottom metal cylinder (groove) structural representation.
Fig. 2 is relatively-high temperature district, a bottom metal tube structural representation.
In Fig. 1, Fig. 2,1 is shell, and 2 is relatively-high temperature district, bottom metal cylinder (groove); 3 is relatively-high temperature district, bottom metal tube; 4 is resistance wire, and 5 is the temperature-sensitive original paper, and 6 is heat-barrier material (as sponge etc.); 7 is liquid (as alcohol etc.); 8 is the relative low-temperature space in top, and 9 are container that live body is housed (as plastic tube etc.), and 10 is biological living; 11 is plug, and 12 are protection liquid.In Fig. 2, several metal tubes 3 are arranged in annular, filling heat-barrier material 6 in the annular and between pipe, the outer resistance wire 4 that is tied with of annular.In Fig. 1, Fig. 2, filling heat-barrier material 6 between resistance wire 4 and shell 1.
When reality is used, freezer unit is put into the cool-bag that an amount of liquid nitrogen is housed, or be placed on below the container that liquid nitrogen is housed.The container 9 that biological living 10 is housed is put into relatively-high temperature district, bottom metal cylinder (groove) 2 or the metal tube 3 that liquid 7 is housed, and make the upper exposed of having only protection liquid 12 in the relative low-temperature space 8 in top.Connect circuit, make this device enter normal operating conditions.
