By adopting the utility model, the drainage joint is directly welded on the PTC body, and the exhaust joint is welded on the drainage joint, thereby simplifying the connection mode, avoiding the use of a three-way joint and improving the installation efficiency of the exhaust structure of the PTC; the structural strength of the joint of the exhaust joint, the drainage joint and the PTC body is also enhanced; the opening of the water drainage joint faces downwards, so that water can be conveniently and smoothly drained out of the PTC body under the action of gravity; the exhaust joint faces upwards, and the exhaust joint is welded on the transverse section of the drainage joint, so that water and gas separation is conveniently carried out at the drainage joint, and smooth discharge of gas is facilitated.

Description

PTC's exhaust structure

Technical Field

The utility model relates to a PTC, especially a PTC's exhaust structure.

Background

The new energy automobile air conditioner heating is provided with a wind heating PTC and a water heating PTC, the water heating PTC system needs to perform exhaust treatment on the whole system, the PTC exhaust pipeline is usually externally connected at present, then a three-way joint is additionally arranged outside the pipeline, and water and gas discharged from the PTC pipeline are separated from the pipeline; although the existing structure can meet the requirements, the three-way joint is used, and the hose also needs three hoops, so that the overall cost is high; in addition, the number of the hoops is large, and the risk of water leakage can occur when the hoops are not installed in place.

Disclosure of Invention

The utility model aims to provide a: aiming at the problems of complicated structure and high cost of an exhaust pipeline of the PTC in the prior art, the PTC exhaust structure with simple structure and low cost is provided.

In order to realize the purpose of the utility model, the utility model provides a following technical scheme:

the utility model provides a PTC's exhaust structure, includes the PTC body, and the welding has the drainage joint that is L shape and opening down on the PTC body, and the drainage joint divide into horizontal section and vertical section, and the welding has the exhaust joint of upwards spending in the horizontal section of drainage joint.

By adopting the technical scheme, the drainage connector is directly welded on the PTC body, and the exhaust connector is welded on the drainage connector, so that the connection mode is simplified, the use of a three-way connector is avoided, and the installation efficiency of the PTC exhaust structure is improved; the structural strength of the joint of the exhaust joint, the drainage joint and the PTC body is also enhanced; the opening of the water drainage joint faces downwards, so that water can be conveniently and smoothly drained out of the PTC body under the action of gravity; the exhaust joint faces upwards, and the exhaust joint is welded on the transverse section of the drainage joint, so that water and gas separation is conveniently carried out at the drainage joint, and smooth discharge of gas is facilitated.

Furthermore, the end part of the exhaust joint is provided with a convex structure and is connected with an exhaust rubber tube, and the exhaust rubber tube is clamped on the exhaust joint through an elastic clamp. The protruding structure facilitates clamping of the exhaust rubber tube by the clamp, air leakage of the exhaust rubber tube is reduced, and a good sealing effect is achieved.

Furthermore, the exhaust joint is connected with an expansion kettle through an exhaust rubber hose. The gas entering the expansion kettle from the exhaust joint contains gas, the gas and the liquid can be further separated in the expansion kettle, and the gas is exhausted from the upper part of the expansion kettle.

Furthermore, the end part of the drainage joint is provided with a convex structure and is connected with a drainage pipeline, and the other end of the drainage pipeline is connected with a warm air water tank. The protruding structure facilitates clamping of the water discharge pipeline by the clamp, and water enters the warm air water tank through the water discharge pipeline.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that: the drainage connector is directly welded on the PTC body, and the exhaust connector is welded on the drainage connector, so that the connection mode is simplified, the use of a three-way connector is avoided, and the installation efficiency of the PTC exhaust structure is improved; the structural strength of the joint of the exhaust joint, the drainage joint and the PTC body is also enhanced; the opening of the water drainage joint faces downwards, so that water can be conveniently and smoothly drained out of the PTC body under the action of gravity; the exhaust joint faces upwards, and the exhaust joint is welded on the transverse section of the drainage joint, so that water and gas separation is conveniently carried out at the drainage joint, and smooth discharge of gas is facilitated.
