Abstract

The invention belongs to the technical field of heat exchangers, and discloses an anti-frost device and a heat exchanger. The anti-frost device comprises fins, a bottom plate and a pipeline assembly, the fins are installed on the bottom plate, an air flow channel is arranged between the fins and the bottom plate, the pipeline assembly comprises a liquid inlet pipe and bottom branch pipes, and the liquid inlet pipe communicates with the bottom branch pipes. The bottom branch pipes are laid at the ends, close to the bottom plate, of the fins, one-way pieces are arranged on the bottom branch pipes, and the flow guide direction of the one-way pieces is from the bottom branch pipes to the liquid inlet pipe. The heat exchanger comprises a box body and the anti-frost device, the anti-frost device is installed on the box body, and the bottom plate is located at the bottom of the box body. The pipeline assembly can conduct a refrigerant, when heating work is executed, the low-pressure and low-temperature refrigerant does not pass through the bottom branch pipes at the ends, close to the bottom plate, of the fins, freezing caused by the too low temperature of the bottom plate is prevented, the air flow channel can increase the air flow, volatilization of accumulated water on the bottom plate is accelerated, and then the heat exchange performance of the heat exchanger is improved.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to an antifreeze device and a heat exchanger. Background technique [0002] Due to the low temperature and high humidity in the northern Xinjiang area, when the air conditioner unit is heating in this area, the throttling low-temperature and low-pressure refrigerant liquid enters the heat exchanger, evaporates and absorbs heat, so that the temperature of the side wall of the heat exchanger continues to drop. The side wall of the heater is prone to icing or water vapor condensation. Among them, the bottom of the current finned heat exchanger is due to factors such as uneven air volume and water flow to the bottom that cause the bottom airflow to cool too quickly, causing the bottom of the heat exchanger to freeze or water vapor to condense most seriously, thereby reducing the heat transfer of the heat exchanger The coefficient increases the flow resistance on the air side an...
