Description
This utility model relates to a kind of automatic heat sink that is applicable to the Automatic Cycle blood therapeutic equipment, and it is to be the too high refrigerating plant of control automatically of the blood circulation ambient temperature that prevents to be shone by quartz burner.
Medically, in order to treat certain disease, need to use the Automatic Cycle blood therapeutic equipment, irradiation is to carry out in the housing of a sealing to blood circulation because with quartz burner, the large-powder ultraviolet fluorescent tube can send certain infrared light (producing certain heat), make that temperature raises in the housing, and make illuminated blood heat rising it in, thereby cause causing behind the blood recovery discomfort of human body.
The purpose of this utility model just is to an automatic heat sink is provided around the blood circulation that is shone by quartz burner in the Automatic Cycle blood therapeutic equipment, in case during irradiation, the blood circulation ambient temperature is elevated to uniform temperature, this device will reduce the blood circulation ambient temperature automatically, so that guarantee the therapeutic effect of autohemotherapy.
The purpose of this utility model is to realize by following measure: this automatically heat sink form by being arranged on the semiconductor cooling device of controlling by supervisory circuit on automatic blood therapy apparatus blood circulation pipe next door and blower fan, the temperature control device that is contained on the therapy apparatus casing, refrigerating plant is arranged on the dividing plate of therapy apparatus casing, make whole therapy apparatus inner chamber be divided into refrigerating chamber and heat radiation chamber, the blood circulation pipe is arranged in refrigerating chamber, offers air vent on the therapy apparatus casing on refrigerating plant top.
In this utility model, semiconductor cooling device is selected semiconductor chilling plate for use, and the both sides of cooling piece respectively are provided with refrigeration conductive sheet and fin; Supervisory circuit is made up of thermostat relay attraction circuit and semiconductor chilling plate power-on circuit two parts, the thermostat relay attraction circuit is by resistance R 3 R4, negative temperature coefficient resister R1 R2, follower IC1, audion T1 T2, relay J, protection diode D forms, the semiconductor chilling plate power-on circuit is the normally-closed contact J1 by relay J, and semiconductor chilling plate and the hot protective relay Jt that is fixed on the fin form; Temp-controlling element is selected two negative temperature coefficient resister R1 for use, and R2, temp-controlling element also can only select a negative temperature coefficient resister R1 for use, and another resistance R 2 is a conventional, electric-resistance.
The blower fan that is contained on the therapy apparatus casing is two, and one is the air exhauster that is contained in refrigerating chamber one side, and another is the cooling fan that is contained in heat radiation chamber one side.
Operation principle of the present utility model is: because the temp-controlling element of this device has been selected two negative tempperature coefficient thermistors for use, its resistance is to reduce along with the rising of ambient temperature, when the temperature rising in the irradiation case exceeds suitable temperature, resistance R 1 R2 of two negative temperature coefficients sends this information to by control circuit and is used for refrigerating semiconductor chilling plate, cooling piece is promptly started working, (in the face of blood circulation pipe one side) begins the refrigerating while in the cooling piece front, its back side begins to the heat radiation of heat radiation case, the cooling fan that is located at heat radiation chamber one side is extracted heat outside the heat radiation chamber out, when temperature is reduced in the suitable temperature scope in the refrigeration case (being quartz burner irradiation case), two negative temperature coefficient resisters can feed back to control circuit to this temperature information, the semiconductor chilling plate outage is quit work, thereby reach the purpose of A.T.C.
Advantage of the present utility model is: this refrigerant system design is reasonable, and circuit working is safe and reliable, can remain blood circulation under suitable ambient temperature, the therapeutic effect of the comfortable and autohemotherapy of human body during with the assurance blood recovery.
The drawing of accompanying drawing is described as follows:
Fig. 1 is contained in axis side view in the therapy apparatus for this utility model.
