Method for improving heat dissipation capacity of radiator

Abstract

The invention discloses a method for improving heat dissipation capacity of a radiator, and a device of the method. The method comprises following steps: fluid flows in a pipeline, local energy lossesof fluid in the pipeline are determined, fluid flows in an inlet pipefitting, local energy losses of fluid in the inlet pipefitting are determined, the flowing speed of fluid entering the radiator iscompared, and the heat dissipation efficiency of the radiator is compared. The device structurally comprises a fluid guide flow pipeline, the tail end of the pipeline is communicated with the inlet pipefitting, the tail end of the inlet pipefitting is communicated with the radiator, and a gradual shrinkage flow guide cavity is formed in the inlet pipefitting. A vortex region is avoided, the localresistance is reduced, and the resistance reduction effect is obvious; the flow speed of the fluid entering the radiator is increased, the turbulent condition of the fluid entering the radiator is enhanced, the heat dissipation efficiency of the radiator is improved, due to structural integration design, the possibility of local damage of the pipeline is effectively reduced, cleaning is convenient, and accumulation of impurities at the corners is avoided.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a method and a device for enhancing the heat dissipation capacity of a radiator. Background technique [0002] At present, due to the mismatch between the pipes connected to the radiator and the pipes provided by the pipe network, it is necessary to reduce the diameter. The common method is to connect with inner threads or nuts. The flow will not turn directly like the pipe wall. Therefore, at the joint of the pipe reducing diameter, the main flow of the fluid is separated from the pipe wall. [0003] A vortex area is formed between the main flow and the pipe wall. The formation of the vortex area causes a loss of local resistance. Due to the increase of local resistance, the loss of kinetic energy causes the power of the fluid at the end of the heating system pipe network to be insufficient, and the flow rate of the fluid entering the radiator decreases, resulting in heat dissi...

[0002] At present, due to the mismatch between the pipes connected to the radiator and the pipes provided by the pipe network, it is necessary to reduce the diameter. The common method is to connect with inner threads or nuts. The flow will not be turned directly like the pipe wall, so, at the joint of the pipe reducing diameter, there will be a phenomenon that the main flow of the fluid is separated from the pipe wall

[0003] A vortex area is formed between the main flow and the pipe wall. The formation of the vortex area causes a loss of local resistance. Due to the increase of local resistance, the loss of kinetic energy causes the power of the fluid at the end of the heating system pipe network to be insufficient, and the flow rate of the fluid entering the radiator decreases, resulting in heat dissipation. The heat dissipation efficiency of the device is reduced, which reduces people's thermal comfort
