Reaction disc heating system for biochemical immunization

The invention discloses a reaction disc heating system for biochemical immunization. A sealed space is formed by a reaction disc bottom plate pasted with sealing heat preservation cotton, a heating ring, a direct heating disc cover assembly and a reaction disc cover. In the sealed space, dust prevention is facilitated, air convection is prevented from taking away heat, the heating efficiency is improved, the heating ring is directly heated by a main heating system, the heating belongs to solid direct heating, liquid is not needed as a medium, and the characteristic of environmental protectionis reflected. An auxiliary heating system is used for recycling heat dissipated by a heating element; the characteristic of environmental protection is reflected; air in the reaction disc is subjectedto forced high-speed circulating convection, the heat transfer efficiency is improved through air high-speed convection, the control compensation is carried out according to the environment temperature, a temperature control
