Description

Technical Field

[0001] This utility model relates to the technical field of heat pumps, and more specifically, to the design of a water receiving pan assembly for a heat pump. Background Technology

[0002] In heat pump systems, a top-discharge airflow design is typically used, with the finned heat exchanger at the top. The finned drip tray is primarily used to collect condensate, water droplets from the evaporator, and other liquids. Due to the operating principle of the heat pump and the temperature difference in the external environment, the drip tray is susceptible to excessively low temperatures or high humidity, leading to icing of water droplets. Icing not only affects the heat exchange efficiency of the equipment but can also cause a decrease in system efficiency, equipment damage, or even operational malfunctions.

[0003] Common anti-icing designs mainly involve adding heating bands around the fins. While this heating method can effectively prevent icing, the large contact area between the fins and the surrounding sheet metal necessitates a large number of heating bands, leading to excessive energy consumption and system complexity.

[0004] Existing technology discloses a water receiving tray assembly, comprising: a water receiving tray with a central hollow hole in its center, and an upward-facing water-retaining flange surrounding the edge of the central hollow hole; a plurality of drainage holes spaced apart around the outer edge of the water receiving tray; a protrusion covering the area of ​​the central hollow hole on the water receiving tray, with the water-retaining flange covered inside the protrusion; and a drainage channel disposed at the bottom of the water receiving tray to collect water leakage from the drainage holes. In this design, the drainage channel is located at the bottom of the water receiving tray. In actual installation, the water receiving tray and the drainage channel are respectively mounted on the surrounding sheet metal. The contact area between the water receiving tray and the equipment frame is relatively large, which increases the risk of icing due to heat conduction. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies where the large contact area between the water tray and the surrounding equipment frame makes it easy for water to freeze. This invention provides a water tray assembly for a heat pump that reduces the contact area between the water tray module and the equipment frame, thereby reducing heat conduction and the risk of freezing.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A heat pump water receiving tray assembly is provided, including a water guide plate, a water receiving tray module, and a drain channel module. The water receiving tray module has a hollow hole in its center. The water guide plate covers the hollow hole and is connected to the outer periphery of the water guide plate. The water receiving tray module has a plurality of drainage holes. The drain channel module is connected to the bottom of the water receiving tray module and has drainage holes. The drain channel module extends away from the hollow hole, and the distance between the outer edge of the drain channel module and the water guide plate is greater than the distance between the outer edge of the water receiving tray module and the water guide plate.

[0008] The heat pump water receiving tray assembly of this utility model has fins that can be mounted on the water receiving tray module. A water guide plate is set in the middle of the water receiving tray module, so that water falling into the middle of the water receiving tray assembly can flow to the water receiving tray module and flow into the drainage channel module through the drainage hole, and then be discharged through the drainage hole. At the same time, the distance between the outer edge of the drainage channel module and the water guide plate is greater than the distance between the outer edge of the water receiving tray module and the water guide plate, which can reduce the contact area between the water receiving tray module and the surrounding equipment frame, effectively reduce the heat conduction path, and reduce the risk of icing.

[0009] Furthermore, the water receiving tray module includes two first water receiving trays and two second water receiving trays, and the drainage trough module includes two first drainage troughs and two second drainage troughs. One end of the water guide plate is provided with a first water-blocking folded edge, the two second water receiving trays are connected to the other end of the water guide plate, the two first water receiving trays are respectively connected to both sides of the water guide plate, one end of the first water receiving tray is provided with a second water-blocking folded edge, the first drainage trough is connected to the bottom of the first water receiving tray, the second drainage trough is connected to the bottom of the second water receiving tray, and the first drainage trough and the second drainage trough extend away from the water guide plate. The first water receiving tray and the second water receiving tray are respectively provided with the water leakage hole, the two second drainage troughs are connected to one end of the two first drainage troughs, and the other end of the first drainage trough is provided with a drainage hole. The fins are installed on the first and second water receiving trays. In use, the accumulated water flows along the guide plate to the first and second water receiving trays. At one end of the guide plate, the water flow is blocked by the first water-blocking fold, and the water flows to the first water receiving tray. At the same time, the water flow is blocked by the second water-blocking fold, and the accumulated water is quickly collected by the first and second drainage channels through the drain hole. The accumulated water in the two second drainage channels flows into the two first drainage channels and is quickly discharged through the drain hole, avoiding water stagnation and freezing.

[0010] Furthermore, a slot is provided at one end of the first water receiving tray. Inserts are provided at both ends of the fin. By aligning the two inserts with the slots on the two first water receiving trays and placing the fin on the first and second water receiving trays, the strength of the fin support can be guaranteed.

[0011] Furthermore, the outer edge of the first water receiving tray is provided with a pleated edge for connection with the fins. Each end of the fin is provided with a fixing plate, which is fixedly connected to the pleated edge via a connector to ensure stable installation of the fins.

[0012] Furthermore, one end of the first drainage trough is provided with an insertion hole, and one end of each of the two second drainage troughs is inserted into the insertion hole of the two first drainage troughs respectively. Some of the accumulated water flows along the water guide plate to the second water receiving tray and then quickly flows into the second drainage trough through the drain hole on the second water receiving tray. The accumulated water in the first drainage trough flows into the first drainage trough through the insertion hole and is finally discharged from the drain hole.

[0013] Furthermore, the bottom of the second drainage trough is inclined, and the bottoms of the two second drainage troughs gradually decrease from the end closest to each other to the end furthest from each other. This facilitates the rapid flow of accumulated water from the second drainage trough into the first drainage trough.

[0014] Furthermore, the bottom of the first drainage trough is inclined, and the bottom of the first drainage trough gradually decreases from the end connected to the second drainage trough to the end away from the second drainage trough. This facilitates the rapid collection of water accumulated in the first drainage trough into the drain hole for discharge, avoiding freezing and blockage problems caused by stagnant water flow, and ensuring the stable operation of the heat pump system.

[0015] Furthermore, the first water receiving tray and the first drainage channel are integrally bent and formed, as are the second water receiving tray and the second drainage channel. The first water receiving tray and the first drainage channel are bent and formed from the same sheet metal, and the second water receiving tray and the second drainage channel are bent and formed from the same sheet metal. This simplifies the manufacturing process, reduces welding and connection parts, thereby lowering manufacturing costs and improving the stability and sealing of the structure.

[0016] Furthermore, reinforcing ribs are provided between the first water receiving tray and the first drainage trough, and between the second water receiving tray and the second drainage trough, and these reinforcing ribs are also connected to the equipment frame. These reinforcing ribs enhance the strength of the integrally bent structure and prevent deformation during use.

[0017] Furthermore, the first drainage groove is provided with a first boss and a groove, the distance between the first boss and the drainage hole is less than the distance between the groove and the drainage hole, the second drainage groove is provided with a second boss, and the first boss, the groove and the second boss are respectively connected to different reinforcing ribs.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This reduces the contact area between the water tray module and the surrounding equipment frame, effectively reducing the heat conduction path and lowering the risk of icing. Attached Figure Description
