Abstract

The utility model provides a heat exchanger air inlet interface, includes the drum, and the side of drum is the conical surface, and the top surface diameter of drum is less than its bottom surface diameter, and the bottom of drum is connected with a head, and the head is the platykurtic, and the top surface of head is the curved surface of kickup, all passes through the circular arc transition between the top surface of head and its four sides, is provided with two at least first strengthening ribs between the side of drum and the four sides of head respectively, and first strengthening rib is along the length direction interval arrangement of the side of head. The utility model discloses a side of drum adopts the form of conical surface, can avoid two sections upper and lower hookup location's sudden change, makes to get into that gas distribution is more even, and pressure loss is littleer. The connector adopts a two-section structure of the cylinder and the end enclosure, so that the strength of the connector is enhanced, the bearing capacity is improved, the number of the first reinforcing ribs is reduced, the welding stress is reduced, the thickness of the plate is reduced, the thermal deformation of the first reinforcing ribs after welding is reduced, the welding workload is reduced, the production efficiency is improved, and the cost is saved.

Description

Air inlet connector of heat exchanger

Technical Field

The utility model relates to the field of machinary, especially, relate to heat exchanger, especially a heat exchanger air inlet interface.

Background

An air inlet of the heat exchanger needs to be welded with a connector to be connected with a pipeline. In the prior art, the compressive strength of the air inlet interface is low, and in the application occasions with high pressure, a plurality of reinforcing ribs need to be welded to improve the pressure bearing capacity, but the welding stress of the reinforcing ribs can be increased, so that the deformation is easy to occur. In addition, when gas passes through the interface, the gas distribution is uneven and the pressure loss is large.

Disclosure of Invention

An object of the utility model is to provide a heat exchanger air inlet interface, this kind of heat exchanger air inlet interface solve the lower class of technical problem of air inlet interface bearing capacity among the prior art. The utility model discloses a heat exchanger air inlet interface, including the drum, the side of drum is the conical surface, and the top surface diameter of drum is less than its bottom surface diameter, and the bottom of drum is connected with a head, and the head is the platykurtic, and the top surface of head is the curved surface of kickup, all passes through the circular arc transition between the top surface of head and its four sides, is provided with two at least first strengthening ribs between the side of drum and four sides of head respectively, and the length direction interval arrangement of the side of head is followed to first strengthening rib.

Furthermore, a second reinforcing rib is arranged in the seal head.

Compared with the prior art, the utility model, its effect is positive and obvious. The utility model discloses a side of drum of heat exchanger air inlet interface adopts the form of conical surface, can avoid two sections hookup location's sudden change from top to bottom, makes to get into that gas distribution is more even, and pressure loss is littleer. The connector adopts a two-section structure of the cylinder and the end enclosure, so that the strength of the connector is enhanced, the bearing capacity is improved, the number of the first reinforcing ribs is reduced, the welding stress is reduced, the thickness of the plate is reduced, the thermal deformation of the first reinforcing ribs after welding is reduced, the welding workload is reduced, the production efficiency is improved, and the cost is saved.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments, but the present invention is not limited to this embodiment, and the protection scope of the present invention should be included in all similar structures and similar variations thereof. The utility model provides an upper and lower, preceding, back, left and right equidirectional use only for the description convenience, it is not right the technical scheme's of the utility model restriction.

Example 1

As shown in fig. 1-5, the utility model discloses a heat exchanger air inlet interface, including drum 1, the side of drum 1 is the conical surface, and the top surface diameter of drum 1 is less than its bottom surface diameter, and the bottom of drum 1 is connected with a head 2, and head 2 is the platykurtic, and top surface 3 of head 2 is the curved surface of kickup, all passes through circular arc 4 transition between top surface 3 of head 2 and its four sides, is provided with two at least first strengthening ribs 5 between the side of drum 1 and four sides of head 2 respectively, and the length direction interval arrangement of the side of head 2 is followed to first strengthening rib 5.

Furthermore, a second reinforcing rib 6 is arranged in the seal head 2.

The working principle of the embodiment is as follows:

the utility model discloses a heat exchanger air inlet interface welding is on the heat exchanger, and the air-supply line is connected to drum 1. The side surface of the cylinder 1 adopts a conical surface form, so that sudden change of the connecting positions of the upper section and the lower section can be avoided, the distribution of the entering gas is more uniform, and the pressure loss is smaller. The connector adopts a two-section structure of the cylinder 1 and the seal head 2, so that the strength of the connector is enhanced, the bearing capacity is improved, the number of the first reinforcing ribs 5 is reduced, the welding stress is reduced, the plate thickness is reduced, the thermal deformation of the first reinforcing ribs 5 after welding is reduced, the welding workload is reduced, the production efficiency is improved, and the cost is saved.
