AI Technical Summary

Technical Problem

Existing heat pump units are prone to dust accumulation on the evaporator surface in dusty environments, which affects heat exchange efficiency. In addition, uneven airflow from the fan creates dead zones at the top and bottom edges of the evaporator, further reducing heat exchange efficiency.

Method used

The spiral tube design combines a cleaning mechanism and a guiding mechanism. The spiral tube rotates to accelerate air circulation, and the guide plate dynamically adjusts the airflow direction. Together with the brush, it cleans dust and ensures that the airflow evenly covers the surface of the spiral tube, preventing dust accumulation.

Benefits of technology

It improves the utilization rate of heat exchange area, enhances heat exchange efficiency, reduces aerodynamic noise, ensures efficient dust removal and uniform airflow, and prevents dust from re-adhering.

Abstract

The application relates to a gradient flow temperature control heat exchange unit and relates to the technical field of heat exchange units, which comprises a machine box containing two chambers, a cooling mechanism, a cleaning mechanism and a guiding mechanism. Liquid refrigerant is allowed to exchange heat with air through a spiral pipe of the cooling mechanism. The rotating spiral pipe accelerates the circulation of the surrounding air and allows dust to uniformly adhere. Meanwhile, the cleaning mechanism cooperates with the rotating spiral pipe and a spiral sliding groove to allow a brush plate in the cleaning mechanism to pass through the spiral pipe for the whole process, so that the surface dust of the spiral pipe is cleaned. The guiding mechanism dynamically adjusts the direction of the gas entering the chamber by using a swing guide plate, so that the airflow can cover every corner in the chamber, air flows through both ends of the spiral pipe, the utilization rate of the heat exchange area of the spiral pipe is significantly improved, and through cooperation of the cleaning mechanism and the guiding mechanism, the airflow direction is inclined to the sliding direction during cleaning by using the guiding mechanism, so that dust is prevented from falling on the surface of the spiral pipe which has just been cleaned.
