Clamping Technology of Box Type Thermoelectric Power Generation System

Abstract

The invention discloses a clamping process for a box-type thermoelectric power generation system. The clamping process comprises the following steps: S1, performing optimal selection of thermoelectric modules: selecting the thermoelectric modules equal in dimension by using calipers; S2, performing shape and position compensation of the thermoelectric modules: arranging copper sheets with corresponding thickness; S3, pre-clamping phi structural steel: selecting a pair of gauges, and arranging the gauges on the phi structural steel through open slots formed in the gauges; S5, applying a clamping force: respectively forming threaded holes in each phi structural steel, and installing a compression screw in each threaded hole, wherein the bottom face of each compression screw is contacted with a pressure strip. The clamping process disclosed by the invention has the advantages that the operation is simple; clamping is reliable; the thermoelectric modules can be effectively ensured to be fixed in position, and moreover, the thermoelectric modules are fully contacted with a cold and hot end, so that the contact thermal resistance between the thermoelectric modules and the cold and hot end is reduced, and the energy transformation ratio and the generating capacity of the power generation system are improved.

Description

Technical field [0001] The invention relates to the technical field of box-type thermoelectric power generation systems, in particular to a clamping process of a box-type thermoelectric power generation system. Background technique [0002] The box-type thermoelectric power generation system uses the temperature difference between the two ends of the thermoelectric module to generate electromotive force to supply power to the battery and realize the effective use of gasoline energy. The traditional clamping process is difficult to achieve effective compression of the thermoelectric module. When installing or replacing the thermoelectric module, it will cause the position of the thermoelectric module to change, and invalid clamping will also cause poor contact between the thermoelectric module and the hot and cold ends. As a result, the thermal contact resistance becomes larger, and the overall energy conversion rate and power generation of the power generation system are reduced....

Problems solved by technology

The traditional clamping process is difficult to achieve effective compression of the thermoelectric module. When installing or replacing the thermoelectric module, the position of the thermoelectric module will change. Moreover, ineffective clamping will also cause poor contact between the thermoelectric module and the hot and cold ends. As a result, the contact thermal resistance becomes larger, reducing the overall energy conversion rate and power generation of the power generation system

Especially after the power generation system is installed on the vehicle, due to the various driving conditions of the vehicle, ineffective clamping will loosen the thermoelectric module, which not only affects the power generation, but also affects the safety of the vehicle
