A heat dissipation device for a temperature control system of a PCR detector

Abstract

The invention relates to a heat dissipation device for a temperature control system of a PCR detector, which comprises a temperature control system, a heat conduction mechanism and a heat dissipationchassis. Temperature control system refers to the system and structure of temperature control required by PCR detector when it is running. The heat conduction mechanism comprises a heat conduction metal layer, a heat conduction pipe and a heat conduction liquid; The heat-conducting metal layer is closely connected with the heating and refrigerating devices in the temperature control system which need to dissipate heat through the heat-conducting medium. The heat-conducting metal layer contains a cavity filled with a heat-conducting liquid, and the cavity is connected with a heat-conducting pipe, the cavity of the heat-conducting metal layer is communicated with the cavity of the heat-conducting pipe, and the heat of the heating refrigeration device in the temperature control system needingheat dissipation is transferred to the heat-conducting liquid in the cavity of the heat-conducting metal layer through the heat-conducting metal layer. The invention is particularly suitable for miniaturization and portable PCR detector, so that the heat dissipation part occupies much less instrument space, and the heat dissipation efficiency can be improved, and the cost can be reduced at the same time.

AI Technical Summary

Problems solved by technology

Due to its small size and convenience, the miniaturized and portable PCR rapid detection device has a strong limitation on the heat dissipation space. However, the existing instruments are all made of aluminum or copper radiators and cooling fans for heat dissipation, and the radiators and the size of the cooling fan directly affect the heat dissipation efficiency. Therefore, under the condition of satisfying the performance of the instrument, the heat sink and the cooling fan occupy a large proportion of the space of the instrument.
