Description

A kind of cold drawing of blood plasma quick freezer

Technical field

The utility model relate to utilize cold drawing directly contact carry out quick-frozen work blood plasma quick freezer, particularly blood plasma quick freezer on cold drawing.

Background technology

The quick-frozen of fresh plasma, according to international standard, need be with extremely-30 ℃ of the quick quick-frozens of the DIE Temperature in the plasma bags in 60 minutes, utilizing the instant freezer of the principle work of the direct contact of cold drawing is exactly the equipment of finishing the quick quick-frozen of blood plasma.The cold drawing of this instant freezer, during use, plasma bags directly contacts with cold drawing, makes the quick quick-frozen of blood plasma in the plasma bags, satisfies quality requirement.

Existing cold drawing generally comprises the sealed cavity (inner chamber) be made up of working panel and backboard, refrigerant input pipe, refrigerant efferent duct etc., refrigerant input, efferent duct respectively with cavity UNICOM.

The operation principle of cold drawing is: refrigerant (as cooling mediums such as freon) enters cavity from the refrigerant input pipe, and refrigerant contacts with the inwall of working panel, directly carry out heat exchange after, export from the refrigerant efferent duct.

There is following defective in existing cold drawing: 1, refrigerant only contacts with the inwall of working panel in cavity, and contact area is little, is unfavorable for heat exchange; 2, after refrigerant entered cavity from the refrigerant input pipe, from the output of refrigerant efferent duct, the heat exchange of refrigerant and working panel was insufficient fast.

For above-mentioned reasons, existing blood plasma quick freezer will will reach refrigerating effect preferably at short notice, just needs to strengthen the frequency of heat exchange, will need more powerful equipment that condition is provided like this, thereby cause the weight of application apparatus to increase, energy consumption is bigger simultaneously.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of cold drawing of blood plasma quick freezer is provided, and during this cold drawing work, the heat exchange effect of refrigerant and working panel is good.

The utility model solves the problems of the technologies described above the technical scheme that is adopted:

A kind of blood plasma quick freezer cold drawing, it comprises sealed cavity, refrigerant input pipe, the refrigerant efferent duct of being made up of working panel and backboard, refrigerant input pipe, refrigerant efferent duct and cavity UNICOM; Be provided with fin in the cavity, fin is connected with the inwall of working panel.

In the such scheme, fin is connected with the inwall of backboard.

In the such scheme, have the hole on the fin.

In the such scheme, fin forms the passage from the refrigerant input pipe to the refrigerant efferent duct in cavity.

Compared with prior art, the utility model cold drawing is:

1, be provided with fin in the cavity, fin is connected with the inwall of working panel, and fin is as the solid heat transfer material, can increase the contact area of refrigerant and working panel inwall, help improving the heat exchanger effectiveness between refrigerant and the working panel, improve the quick-frozen effect, reduce power consumption, improve freezing efficiency.

2, fin is connected with the inwall of backboard, can change the direction of travel of refrigerant in cavity, helps increasing the heat exchange of refrigerant and working panel, is beneficial to the even cooling of blood plasma in the plasma bags.

3, have the hole on the fin, refrigerant is walked from the hole in cavity, can slow down the speed of travel of refrigerant in cavity, and the heat exchange that helps increasing refrigerant and working panel is abundant.

4, fin forms the passage from the refrigerant input pipe to the refrigerant efferent duct in cavity, can change the track route of refrigerant in cavity, helps increasing the heat exchange of refrigerant and working panel.

The utility model cold drawing, refrigerant makes heat exchange fully carry out by the heat-transfer matcrial in the cavity, can reduce the charging amount of refrigerant, reduces volume, weight and the relevant supporting auxiliary equipment of fluid reservoir volume capacity, compressor.
