Description

Technical Field

[0001] The utility model relates to an air conditioning system of engineering machinery equipment, in particular to a condensing core pipe orifice fixing structure. Background Art

[0002] The condenser core is an important part of the heat exchange element in the air conditioning assembly. Its main function is to cool the refrigerant, reduce the pressure of the refrigerant, and release heat at the same time. The condenser core is an indispensable heat exchange element in the entire air conditioning system. The pipe mouth is an important part of the condenser core. It is the key part for the refrigerant to enter and exit. In order to facilitate the takeover operation, take the patent number 202220695300.6 as an example. Figure 4 As shown, the inlet pipe interface and the outlet pipe interface of the condensation core are arranged on the same side.

[0003] However, the defects of the prior art are also very obvious, and the specific analysis is as follows:

[0004] Since construction machinery and equipment will constantly vibrate during operation, the pipe mouth of the condenser core of the air-conditioning system in the construction machinery and equipment is prone to shaking and wearing on the entire machine. Once worn, it will cause refrigerant leakage and reduced refrigeration effect. As time goes by, the refrigerant will leak out completely and the air conditioner will not cool. With the widespread promotion of air conditioning in construction machinery, the problems that arise in the use of the air-conditioning condenser core during use should not be underestimated.

[0005] Therefore, the problem of economic losses caused by leakage due to wear of the condenser core tube mouth is an issue that must be solved and improved in the development of the engineering machinery air-conditioning industry. Utility Model Content

[0006] The utility model aims to provide a condensing core pipe opening fixing structure, so as to limit the pipe interface.

[0007] The purpose of the utility model is achieved as follows: a condensing core pipe port fixing structure, comprising a first pipe interface and a second pipe interface fixedly plugged into a condensing core shell, the first pipe interface / the second pipe interface having an outer hexagonal portion, the first pipe interface and the second pipe interface are respectively provided with a first fixing plate and a second fixing plate for limiting, the first fixing plate and the second fixing plate having the same structure and material;

[0008] The first fixing plate / the second fixing plate comprises a fixing plate body, which is fixedly mounted on the outer surface of the condensing core shell. The fixing plate body is C-shaped as a whole and its C-shaped mouth is set as a positioning groove. The outer hexagonal part of the first pipe interface / the second pipe interface is fitted with the positioning groove and matched with the positioning groove.

[0009] The beneficial effect of the utility model is that a fixing plate is added at the tube mouth of the condenser core, so as to facilitate the limiting of the first tube interface and the second tube interface, prevent the first tube interface / the second tube interface from deflecting under the action of vibration, and solve the problems of shaking and wear of the core tube mouth existing in the prior art.

[0016] like Figure 1-3 As shown, a condenser core pipe mouth fixing structure includes a first pipe interface 3 and a second pipe interface 4 which are fixedly inserted into a circular mounting hole of the condenser core shell. The first pipe interface 3 / the second pipe interface 4 has an external hexagonal part. The first pipe interface 3 and the second pipe interface 4 are respectively provided with a first fixing plate 1 and a second fixing plate 2 for limiting. The first fixing plate 1 and the second fixing plate 2 have the same structure and material but different size specifications.

[0017] like Figure 3As shown, the above-mentioned first fixing plate 1 / second fixing plate 2 includes a fixing plate body 5, and the fixing plate body 5 is fixedly mounted on the outer surface of the condensing core shell. The fixing plate body 5 is C-shaped as a whole and its C-shaped mouth is set as a positioning groove 52, and the outer hexagonal part of the first pipe interface 3 / second pipe interface 4 is equipped with the positioning groove 52 and matched with the positioning groove 52, so as to prevent the first pipe interface 3 / second pipe interface 4 from being deflected (also can be understood as self-rotation) under the action of vibration, that is, by the outer hexagonal part of the first pipe interface 3 / second pipe interface 4 being close to the special-shaped positioning groove 52, the first pipe interface 3 / second pipe interface 4 is prevented from being self-rotated in the circular mounting hole of the condensing core shell under the action of vibration, thereby forming a good radial limiting effect.

[0018] As a preferred embodiment, the contour edge of the positioning groove 52 is composed of a pair of parallel straight edges 52b and a bayonet 52a at the bottom of the groove, and the bayonet 52a coincides with the edge of the outer hexagonal portion of the first pipe interface 3 / second pipe interface 4.

[0019] As a preferred embodiment, in order to achieve a better limiting effect, the contour edge of the bayonet 52a has four obtuse angles (similar to the incomplete hexagon formed after part of the edge is cut off), and matches the four corners of the outer hexagonal part of the first pipe interface 3 / second pipe interface 4 one by one, so as to better prevent the first pipe interface 3 / second pipe interface 4 from deflecting under the action of vibration.

[0020] As a preferred embodiment, the junction between the outer edge of the fixing plate body 5 and the straight edge 52b of the positioning groove 52 is configured as a smooth curved chamfer 52c.

[0021] As a preferred embodiment, the outer edge of the fixing plate body 5 is configured to be arc-shaped, and the bayonet 52 a is located at the center of the arc-shaped outer edge of the fixing plate body 5 .

[0022] As a preferred embodiment, the fixing plate body 5 is detachably fixed to the outer surface of the condensing core shell by screws, and the fixing plate body 5 is provided with at least two locking holes 51 for passing the screws.

[0023] As a preferred embodiment, the fixing plate body 5 is provided with two locking holes 51 , so as to facilitate locking of the fixing plate body 5 .

[0024] As a preferred embodiment, the two locking holes 51 are located at the left and right sides of the positioning slot 52 .

[0025] The advantages of adopting the above solution are:

[0026] A fixing plate is added at the condenser core tube mouth to solve the problems of core tube mouth shaking, wear and other problems existing in the prior art. The fixing plate is easy to disassemble and assemble, effectively enhancing the stability of the condenser assembly, thereby solving the problem of refrigerant leakage due to wear of the condenser core tube mouth and reducing the failure rate.
