Description

Technical Field

[0001] The utility model relates to the field of vehicle air conditioners, in particular to an evaporator that is easy to clean. Background Art

[0002] The automotive evaporator is a key component in the automotive air-conditioning system. The main function of the evaporator is to evaporate the low-temperature refrigerant from the expansion valve in a low-pressure environment, converting it into a vapor state, and absorbing heat from the surrounding medium in the process, thereby achieving a cooling effect.

[0003] Traditional automotive evaporators are sealed as a whole. When cleaning, they are flushed with foam and high-pressure gas, which cannot thoroughly clean the inside of the flat tube. There are some dead corners and the cleaning effect is not ideal. Utility Model Content

[0004] The utility model aims to provide an evaporator which is easy to clean and has good cleaning effect.

[0005] The purpose of the utility model is achieved as follows: an evaporator that is easy to clean, comprising an upper header, flat tubes and a lower header, wherein the flat tubes are placed between the upper header and the lower header;

[0006] The upper manifold is composed of four side panels, a bottom plate and a removable top cover. A manifold partition is provided on the central axis of the long side of the upper manifold. A middle docking plate extends from the top of the manifold partition to both sides, and a side docking plate extends inward from the side panel. The side docking plates and the middle docking plate together form two groups of docking planes, and the two groups of docking planes are provided with docking grooves. Two groups of top cover protrusions matching the docking grooves are provided on the lower side of the top cover, and the outer periphery of the top cover protrusions is covered with rubber strips.

[0007] The ends of both sides of the lower collecting pipe are provided with butt joints, and the butt joints are rotatably sealed by a rotating cover.

[0008] Preferably, a first fixing plate is provided on the periphery of the top cover, and a second fixing plate is provided on the periphery of the side plate, and the first fixing plate and the second fixing plate are fixedly connected by bolts.

[0009] Preferably, the docking groove is configured to be V-shaped, the outer contour cross-section of the rubber strip is configured to be V-shaped, and the rubber strip matches the docking groove.

[0010] Preferably, a rubber layer is provided inside the rotating cover, and the rubber layer contacts the end of the butt joint.

[0011] Preferably, a tapered guide portion is provided inside the lower header and near one of its ends.

[0012] Compared with the prior art, the present invention is beneficial in that:

[0013] 1. The upper header is designed to be detachable. Removing the cover exposes the inlet of the flat tubes, allowing a flat cleaning structure to reach inside the flat tubes for cleaning, which is more effective than high-pressure cleaning. Two butt joints are installed at both ends of the lower header, one of which can be connected to a water pipe or high-pressure airflow. Impurities falling into the flat tubes can be discharged from the other butt joint, resulting in high cleaning efficiency.

[0014] 2. The docking structure between the top cover and the upper manifold is optimized, and a V-shaped rubber strip is set to match the docking groove. When the top cover is pressed, the V-shaped rubber strip and the V-shaped docking groove are squeezed to further improve the sealing and avoid leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figure 1-3 As shown, an evaporator that is easy to clean includes an upper header 1, flat tubes 2 and a lower header 3, wherein the flat tubes 2 are placed between the upper header 1 and the lower header 3;

[0023] The upper manifold 1 is composed of four surrounding side panels 101, a bottom panel 102, and a removable top cover 103. A manifold partition 104 is provided on the central axis of the long side of the upper manifold 1. A middle docking plate 1041 extends from the top of the manifold partition 104 to both sides. Side docking plates 1011 extend inward from the side panels 101. The side docking plates 1011 and the middle docking plates 1041 together form two sets of docking planes 4, each of which is provided with docking grooves 401. Two sets of top cover protrusions 1031 matching the docking grooves 401 are provided on the underside of the top cover 103. The outer periphery of the top cover protrusions 1031 is covered with a rubber strip 5.

[0024] The ends of both sides of the lower header 3 are provided with butt joints 301 , which are rotatably sealed by a rotary cover 6 . The lower header adopts a rotary cover structure, and the sealing performance is guaranteed.
