Abstract
The invention discloses a kind of accurate temperature control device of medical refrigerator, including casing：The top board inwall of casing, plate inner wall, two side board inwalls, backboard inwall, door-plate inwall are separately installed with temp probe, and the temp probe is connected respectively to control board；Roof box, base plate, two side boards and postnotum are provided with the evaporator and refrigeration pipe of separate type, refrigeration pipe is distributed according to the route for optimizing, frequency-changeable compressor is connected respectively to each evaporator and refrigeration pipe by multiple electrically-controlled valves, and control board is connected to electrically-controlled valve and frequency-changeable compressor.The present invention coordinates control system using multiple temp probes, temperature height according to feedback controls the power output of frequency-changeable compressor, and the separate type evaporator and refrigeration pipe innovated by Valve controlling, certain temp probe detect this regional temperature it is too high when, then open the valve in this region, evaporator and refrigeration pipe is set to work, bulk temperature in casing is accurate and effect in a balanced way so as to reach.
Description
Technical field：
The present invention relates to medical refrigerator field, the accurate temperature control device of more particularly to a kind of medical refrigerator.
Background technology：
With the development of domestic medical industry, the unit such as most of hospitals and pharmaceutical factory is required for using medical refrigerator, medical refrigerator
Main storage needs medicine, reagent, vaccine, biological products, costly medicine of Cord blood etc., for relatively general civil refrigerator,
Medical refrigerator is stricter for temperature control requirement, once temperature goes wrong, gently then causes loss of drug potency, causes economic damage
Lose, life security that is heavy then injuring patient.
Current medical refrigerator, its refrigerating chamber in the environment of approximate closing, colder air due to sinking than great,
The bottom of casing is gathered in, while hotter air accumulation is in the top of casing.Meanwhile, near the part of evaporator, temperature
It is relatively low, and it is higher away from the portion temperature of evaporator.And the temperature sensor that general medical refrigerator is installed is in the centre of casing
Or lower middle position, the temperature that it is reflected is the temperature at this position, it is impossible to enough represent the actual temperature in whole chamber
Degree.If not solving this problem, even with the computer temperature control system shown with temperature, the temperature of medical refrigerator outside display
The actual temperature that degree can not really reflect inside refrigerating chamber, if foundation of the user using displays temperature as storage medicine,
Can make troubles on the contrary.
The content of the invention：
The purpose of the present invention is directed to shortcoming present in background technology and problem is improved and innovated, there is provided a kind of medical ice
The accurate temperature control device of case.
The technical solution adopted by the present invention is：
A kind of accurate temperature control device of medical refrigerator, including casing：The top board inwall of casing, plate inner wall, two side boards
Inwall, backboard inwall, door-plate inwall are separately installed with temp probe, and the temp probe is connected respectively to control board；Case
Body top board, base plate, two side boards and postnotum are provided with the evaporator and refrigeration pipe of separate type, and refrigeration pipe was according to optimizing
Route distribution, frequency-changeable compressor by multiple electrically-controlled valves be connected respectively to each evaporator and refrigeration pipe, control board
It is connected to electrically-controlled valve and frequency-changeable compressor.
The two side boards inwall is provided with N number of temp probe (3>N>1), temp probe is located at side board centre position and hangs down
Directly form a line.
Compared with prior art, the beneficial effects of the present invention are：
The present invention coordinates control system using multiple temp probes, and the temperature height according to feedback controls the output of frequency-changeable compressor
Power, and the separate type evaporator and refrigeration pipe innovated by Valve controlling, certain temp probe detect this regional temperature
When too high, then open the valve in this region, evaporator and refrigeration pipe is worked, so as to reach bulk temperature in casing it is accurate and
Effect in a balanced way.
Brief description of the drawings：
Fig. 1 is schematic structural view of the invention.
Fig. 2 is refrigeration pipe schematic diagram of the present invention.
Wherein：4 is frequency-changeable compressor, and 5 is electrically-controlled valve, and 6 is filter, and 7 is capillary, and 8 is reservoir, and 9 steam for top board
Hair device and refrigeration pipe, 10 is backboard evaporator and refrigeration pipe, and 11 is base plate evaporator and refrigeration pipe, and 12 is left condenser
And refrigeration pipe, 13 is right condenser and refrigeration pipe, and 14 is defroster duct.
Specific embodiment：
Below in conjunction with the accompanying drawings, the present invention is described in further detail by embodiment：
A kind of accurate temperature control device of medical refrigerator, including casing：The top board inwall of casing 1, plate inner wall, two side boards
Inwall, backboard inwall, door-plate inwall are separately installed with temp probe 2, and the temp probe 2 is connected respectively to control board 3；
The top board of casing 1, base plate, two side boards and postnotum are provided with the evaporator and refrigeration pipe of separate type, and refrigeration pipe is according to excellent
The route distribution changed, frequency-changeable compressor 4 passes through multiple electrically-controlled valves 5 and is connected respectively to each evaporator and refrigeration pipe, controls
Circuit board 3 is connected to electrically-controlled valve and frequency-changeable compressor.
The two side boards inwall is provided with N number of temp probe (3>N>1), temp probe is located at side board centre position and hangs down
Directly form a line.
Embodiment of the present invention is only the description carried out to the preferred embodiment of the present invention, not to the present invention
Spirit and scope are defined, and on the premise of design philosophy of the present invention is not departed from, engineers and technicians are to this hair in this area
The all variations and modifications that bright technical scheme is made, all should fall into protection scope of the present invention, claimed skill of the invention
Art content, has all recorded in detail in the claims.
