Description

TECHNICAL FIELD

[0001] The utility model relates to a refrigeration technical field more particularly, a novel temperature sensing tube assembly. BACKGROUND

[0002] In the prior art, a widely used form is to weld another straight pipe (referred to as a sleeve pipe) made of red copper material on a U-shaped bend or a straight pipe made of red copper material, and the sleeve pipe is inserted into a card made of stainless steel material to form the entire temperature sensing tube assembly. When used by a customer, a temperature sensing probe is inserted into the sleeve pipe, and the sleeve pipe made of red copper material is used to complete temperature collection due to its good heat conductivity. Some use a card made of stainless steel material to clamp the probe in the sleeve pipe, and some weld a part on the outside of the sleeve pipe to fix the temperature sensing probe. These traditional temperature sensing sleeve pipe assemblies have risks such as loosening of the temperature sensing probe due to improper installation of the stainless steel card, high fixed cost of the welded part, and unstable assembly structure, which may cause the temperature sensing probe to loosen. SUMMARY

[0004] A novel temperature sensing tube assembly includes a measured pipe, a temperature sensing heat conduction seat connected to the measured pipe, a heat conduction sheet embedded in the temperature sensing heat conduction seat, the heat conduction sheet being in contact with the measured pipe and made of red copper, a temperature sensing probe for measuring temperature being in contact with multiple surfaces of the temperature sensing heat conduction seat and the heat conduction sheet, and the temperature sensing heat conduction seat and the heat conduction sheet being clamped together. The structure is more stable, the cost is low, the heat conduction sheet is in direct contact with the measured pipe, and temperature collection is more rapid and accurate.

[0005] As a further improvement and supplement to the above-mentioned scheme, the utility model further includes the following additional technical features:

[0006] The temperature sensing heat conduction seat and the heat conduction sheet have a trapezoidal cross section and are in contact with the temperature sensing probe on three surfaces. The structure is more stable, and temperature collection is more rapid and accurate.

[0007] The temperature sensing heat conduction seat is provided with multiple protrusions, and the heat conduction sheet is provided with multiple grooves. The protrusions and the grooves are clamped together. The structure is stable and reliable in connection.

[0008] The temperature sensing heat conduction seat is provided with an inner recessed fixing sheet. The fixing sheet includes two inclined transition sheets on the sides and a transverse stopper. The transition sheets extend inward, and the transition sheets and the stopper are connected. The temperature sensing probe is effectively limited, the structure is reasonable, the stopper increases the fixing width, the fixing is more secure, and the probe is convenient and fast to install, fix, and disassemble.

[0009] One end of the temperature sensing heat conduction seat is provided with an inwardly bent push block. The positioning is more correct and convenient.

[0010] The aforementioned temperature-sensing and heat-conducting base is composed of multiple engaging mechanisms. It is low in cost.

[0011] The tube under test is either an elbow or a straight tube, and the heat-conducting plate is located at the arc-shaped top or side end of the elbow, or at the side end of the straight tube.

[0012] The aforementioned temperature-sensing heat-conducting base and the tested tube are connected longitudinally or in parallel. It has a wide range of applications and meets various different needs.

[0013] The following advantages can be achieved by using this utility model: The temperature sensing probe, the temperature-sensing heat-conducting base, and the heat-conducting sheet are bonded together on three sides, resulting in a more stable structure. The heat-conducting sheet directly contacts the tube being tested, leading to faster and more accurate temperature acquisition, and lower cost. This utility model effectively limits the movement of the temperature sensing probe; the increased width of the stop block ensures a more secure fixation, and the probe is easy and quick to install, fix, and disassemble.

[0022] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1-8 As shown, this utility model is a novel temperature sensing tube assembly.

[0024] The new temperature sensing tube assembly comprises a measured tube 1, a temperature sensing heat conducting seat 2 connected to the measured tube 1, and a heat conducting sheet 3 embedded in the temperature sensing heat conducting seat 2 and adhered to the measured tube 1. The temperature sensing heat conducting seat 2 is made of stainless steel, and the heat conducting sheet 3 is made of red copper. A temperature sensing probe is adhered to multiple surfaces of the temperature sensing heat conducting seat 2 and the heat conducting sheet 3, and the temperature sensing heat conducting seat 2 and the heat conducting sheet 3 are clamped together. The measured tube 1 is welded to the temperature sensing heat conducting seat 2 and the heat conducting sheet 3.

[0025] Further, the temperature sensing heat conducting seat 2 and the heat conducting sheet 3 have a trapezoidal cross section and are adhered to three surfaces of the temperature sensing probe. The transition portions of the temperature sensing heat conducting seat 2 and the heat conducting sheet 3 are connected by arcs.

[0026] Further, the temperature sensing heat conducting seat 2 is provided with multiple protrusions 21, and the heat conducting sheet 3 is provided with multiple grooves 31. The protrusions 21 and the grooves 31 are clamped together. The temperature sensing heat conducting seat 2 and the heat conducting sheet 3 are punched and then curled.

[0027] Further, the temperature sensing heat conducting seat 2 is provided with an inner recessed fixing sheet. The fixing sheet comprises two inclined transition sheets 23 and a transverse stopper 24. The transition sheets 23 extend inwardly, and the transition sheets 23 and the stopper 24 are connected. The stopper 24 limits the temperature sensing probe, and the stopper 24 increases the contact area and stabilizes the connection.

[0028] Further, one end of the temperature sensing heat conducting seat 2 is provided with an inwardly bent push block 25. The push block 25 blocks the temperature sensing probe to position it.

[0029] Further, the temperature sensing heat conducting seat 2 is combined by multiple clamping mechanisms 22. The clamping mechanisms 22 can be any one of the existing technologies. The temperature sensing heat conducting seat 2 is divided into multiple parts, punched, and then welded, which is low in cost.

[0030] Further, the measured tube 1 is an elbow or a straight tube. The heat conducting sheet 3 is arranged at the arc-shaped top end or the side end of the elbow or the side end of the straight tube.

[0031] Further, the temperature sensing heat conducting seat 2 and the measured tube 1 are connected longitudinally or in parallel.

[0032] When the new temperature sensing tube assembly is used, the temperature sensing probe passes through the temperature sensing heat conducting seat 2, is adhered to three surfaces of the temperature sensing heat conducting seat 2 and the heat conducting sheet 3, is fixed by the stopper 24, is positioned by the push block 25, and transmits the temperature of the measured tube 1 to the heat conducting sheet 3. The heat conducting sheet 3 transmits the temperature to the temperature sensing probe to detect it.

[0033] The above is the preferred embodiment of the present application, and does not limit the protection scope of the present application. Any deformation and improvement made by the skilled in the art according to the design idea of the present application shall be considered within the protection scope of the present application.
