Description

Technical Field

[0001] This utility model relates to the field of air conditioning refrigeration technology, and belongs to an air conditioning cold air core with a coolant medium. Background Technology

[0002] The air conditioning core is a key component of the air conditioning assembly, lowering the temperature of the air passing through it to achieve cooling. Simultaneously, it reduces humidity inside the vehicle by condensing water vapor in the air, improving passenger comfort. Unlike conventional evaporator cores that use R134a refrigerant, the air conditioning core is typically used in secondary heat exchange systems with R290 refrigerant, employing ethylene glycol coolant as the cooling medium.

[0003] In existing technologies, conventional cold air cores directly borrow the structure of the warm air core in the air conditioning unit assembly, resulting in low heat exchange efficiency and poor uniformity of core surface temperature. In addition, conventional cold air cores do not have strong drainage performance. The surface temperature of the cold air core is low, and when it encounters air, it will condense water molecules in the air, forming condensation that adheres to the core surface. This condensate can clog the air conditioning unit, leading to leaks or splashing water. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an air conditioning cooling core with a coolant medium.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This application provides an air conditioning cooling core with a coolant medium, comprising a double-layer core. The double-layer core includes two layers of flat tube assemblies, each composed of several flat tubes. Protective plates are provided at both ends of the flat tube assemblies, and fins are provided between the flat tubes at both ends and the protective plates. Dual-chamber water chambers are connected to both sides of the flat tube assemblies. Each dual-chamber water chamber includes an upper dual-chamber water chamber and a lower dual-chamber water chamber. The upper dual-chamber water chamber is connected to the upper side of the flat tube assemblies, and the lower dual-chamber water chamber is connected to the lower side of the flat tube assemblies.

[0007] Preferably, the upper dual-chamber water chamber includes an upper main board, an upper cover, and an upper plug. The upper main board is connected to the upper end of the flat tube assembly, the upper cover is connected to the upper main board, and the upper plug is connected to one end of the upper main board and the upper cover. The upper main board and the upper cover surround and form an inlet chamber and an outlet chamber, which are mutually sealed.

[0008] Preferably, the upper double-chamber water chamber is connected to an inlet pipe and an outlet pipe via a connector at the end away from the upper cover. The inlet pipe is connected to the inlet chamber, and the outlet pipe is connected to the outlet chamber.

[0009] Preferably, the lower dual-chamber water chamber includes a lower main plate, a lower cover, and a lower plug. The lower main plate is connected to the lower end of the flat tube assembly, the lower cover is connected to the lower main plate, and the lower plug is connected to both ends of the lower main plate and the lower cover. The lower main plate and the lower cover surround and form a first transition chamber and a second transition chamber. The first transition chamber and the second transition chamber are interconnected through a flow hole.

[0010] Preferably, both the lower main board and the lower cover are provided with ribs in the middle, and each of the two ribs is provided with a number of grooves at intervals. Drainage holes are provided in the grooves, and the ribs are combined to form a number of flow holes, which are located between the grooves.

[0011] Compared with the prior art, this utility model provides an air conditioning cooling core with coolant as the medium, which has the following beneficial effects:

[0012] 1. Existing cold air cores and warm air cores have the same structure, which is a single-layer core with a single flow channel structure. The surface temperature uniformity of the core is poor. This utility model is a double-layer core with a two-flow channel structure, which has good temperature uniformity and high heat exchange efficiency.

[0013] 2. Existing air cooler cores lack drainage grooves and drainage holes, which is not conducive to the discharge of condensate. The lower double-chamber water chamber of this utility model is provided with ribs, which are combined to form drainage grooves. At the same time, drainage holes are opened in the drainage grooves to facilitate the collection of condensate adhering to the surface of the core and to flow out from the openings in the core, thereby improving the drainage performance of the core and preventing water leakage or splashing.

[0014] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description
