Water containing plate for heat exchanger

Abstract

The invention relates to the technical field of heat exchangers, in particular to a water containing plate for a heat exchanger. The water containing plate for the heat exchanger comprises a bottom plate and a water guiding plate, wherein the water guiding plate is arranged on the periphery of the bottom plate in a surrounding way and can be detachably connected with the bottom plate; multiple first notches are arranged on the peripheral side of the bottom plate; the water guiding plate is provided with multiple second notches corresponding to the first notches; the first notches and the corresponding second notches enclose to form multiple drain holes for draining; and a hole wall of each drain hole downwards extends out of a flow guiding part. Compared with the prior art, the multiple drain holes are formed between the water guiding plate and the bottom plate and are formed in the periphery of the bottom plate in a surrounding way, the drain holes extend out of the flow guiding part,and during a draining process, the partial adhesion capacity and the surface tension of water are eliminated through the flow guiding part, so that defrosting water and condensation water can be drained out of the water containing plate along the flow guiding part, the water can be drained smoothly, and the occurrence of the phenomenon that the drain holes are secondarily frozen is avoided; and in addition, an electric auxiliary heating part can be omitted, so that the manufacturing cost is reduced, and the potential safety hazard is eliminated.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a water receiving tray for a heat exchanger. Background technique [0002] The heat exchanger of the air conditioner generally produces condensed water when it is working, and the condensed water will flow along the surface of the heat exchange tube on the heat exchanger to the bottom of the heat exchanger, so the bottom of the heat exchanger is generally equipped with a water collector Pan structure, the water pan structure is used to catch the condensed water on the heat exchanger and discharge it through the pipeline. [0003] The existing way to solve the freezing problem of the water tray is generally to install electric auxiliary heating parts around the water tray, and prevent or solve the freezing problem of the water tray through the heating of the heating parts. The existing water tray mainly uses Drainage of the drain structure, this method has the phenomenon ...

Problems solved by technology

[0003] The existing way to solve the freezing problem of the water tray is generally to install electric auxiliary heating parts around the water tray, and prevent or solve the freezing problem of the water tray through the heating of the heating parts. The existing water tray mainly uses Drainage of the drain structure, this method has the phenomenon that the drainage of the drain is not complete, which is easy to cause secondary freezing, and the drainage is carried out through the drain, causing the water to spill around and splash on the electronic components when draining; and the use of electric assist The heating of the heating parts consumes a lot of electric energy, which is contrary to the purpose of energy saving of the equipment, and also increases the cost of use. In addition, the electric auxiliary heating is easy to damage and leak electricity after soaking in water for a long time, which will cause the machine to be electrified and pose a certain threat to personal safety.
