Description

Technical Field

[0001] The utility model relates to the field of heat pumps and water heaters, and in particular to a heat pump unit with an independent air duct of a heat exchanger and a condensed water collector. Background Art

[0002] The current air source heat pump unit mainly includes water tank, compressor, fin heat exchanger, liquid storage tank and other structures. However, the fin heat exchanger is often arranged with other components. The incoming air needs to pass through other components and cause losses before passing through the fin heat exchanger, resulting in low heat exchange efficiency. In addition, the fin heat exchanger needs to be fixed with additional fixed sheet metal, and the process is cumbersome and requires many consumables. The water tray at the bottom is flat, and the condensed water is collected and discharged. When the air is incoming for heat exchange, the condensed water is easily blown away. The water can damage the components and rust, affecting the service life of the machine, and may also freeze. Utility Model Content

The heat exchanger is located in the upper part of the box shell to form an independent air duct, which reduces the installation process and saves costs. The incoming air is directly discharged after passing through the heat exchanger to ensure the heat exchange efficiency. At the same time, the structure of the water tray can collect condensate, and the condensate is automatically collected and quickly drained in time, which effectively improves the cleanliness and prevents ice.

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] In the description of the utility model, it is necessary to understand that the directions or positional relationships indicated by the terms "front", "rear", "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model.

[0022] The present embodiment discloses a heat pump unit with an independent air duct for a heat exchanger and a condensate collection device, comprising a vertical water tank 2, a box shell 1 is arranged on one side of the vertical water tank 2, and the box shell 1 comprises a top plate, a front panel, a left side plate and a right side plate, and the top plate, the front panel, the left side plate and the right side plate form a box cavity with the outer wall of the vertical water tank 2. A compressor and other components are installed at the lower part of the box shell 1, and a water receiving pan 3 is fixed at the upper part of the box shell 1. The front and rear sides of the water receiving pan 3 are both provided with an upwardly inclined water collecting plate 4, so that the water receiving pan 3 as a whole is in a V-shaped structure in the front and rear directions, which can collect condensate. The water receiving pan 3 is processed with an upward flange around it to prevent the condensate from overflowing. A drainage hole 5 is processed at the bottom of the water receiving pan 3, and the drainage hole 5 is a downward flange hole, which is convenient for connecting with the centralized drainage pipe. With such a design, when the condensate is concentrated at the bottom of the water receiving pan 3, it can be discharged in time through the drainage hole.

[0023] A vertically distributed support plate frame 6 is processed on the surface of the water receiving tray 3. The top of the support plate frame 6 is fixedly connected to the top plate. The support plate frame 6 and the water receiving tray 3 are designed in an integrated manner. A heat exchanger 7 is installed on the support plate frame 6 by a bolt assembly. In this embodiment, the heat exchanger 7 generally adopts a fin heat exchanger. A fan 10 is also arranged in front of the heat exchanger, and the fan 10 is fixed on the inner wall of the box shell 1. With such a design, the heat exchanger is in an independent air duct, and there are no components around it, ensuring that the incoming air passes directly through the heat exchanger 7. An exhaust mesh 8 facing the blades of the fan is processed on the front panel, and an inlet mesh 9 facing the heat exchanger is processed on the surface of the left and right panels.

[0024] The specific working principle of the heat pump unit with independent air duct of heat exchanger and condensate collection of the utility model is as follows:

[0025] When the fan is running, the outside wind enters from the air inlet mesh of the left and right panels, passes through the heat exchanger for heat exchange, and then is discharged from the exhaust mesh of the front panel. The upper space of the box shell 1 where the heat exchanger is located forms an independent exclusive air duct to improve the heat exchange effect. The air intake does not pass through other components and is only used for heat exchange in the heat exchanger, and the heat is taken away in time to improve the heat exchange efficiency. The water receiving tray 3 and the support plate frame 6 are an integrated plate, which is processed and formed in one piece. There is no need to add an additional fin heat exchanger fixing plate, which reduces the installation process and reduces the cost. The fin heat exchanger is more firmly fixed, and there is no gap between the fixed plate and the water receiving tray 3, which effectively prevents water leakage; the sloped water receiving tray 3 can effectively realize the automatic collection and discharge of condensed water, collect the water carried away by the wind to the greatest extent, and the sloped water uses gravity to automatically collect the water in time, and can realize centralized and rapid drainage, improve the cleanliness of the entire equipment area, prevent the spread of scattered drainage and damage and rust of components, and improve the service life of the machine. At the same time, it can effectively prevent icing and ensure the heat exchange efficiency of the fin heat exchanger.
