Temperature sensing probe fixing structure for heat exchanger

Abstract

The invention discloses a temperature sensing probe fixing structure for a heat exchanger. The temperature sensing probe fixing structure comprises an energy transfer type dry ice spraying conversion state device, a solid-liquid conversion universal type wrapped heat exchange tube height adjusting and clamping device, a plug-in type UV fixed irradiation device and an adjustable anti-explosion temperature sensing probe fixing and placing device. The invention belongs to the technical field of temperature sensing probe fixing structures, and particularly relates to a temperature sensing probe fixing structure for a heat exchanger. The problems that a heat exchange tube is easily damaged by welding and the welding position is easily broken by stress concentration because a temperature sensing probe in the current market is fixed on the heat exchange tube in a welding manner are effectively solved, and the problems of welding breakage and stress concentration are avoided. Meanwhile, the physical state conversion principle of an object is adopted, liquid glue in a soft supporting bag is converted into solid glue, and the contradiction between 'soft' and 'not soft' is overcome ('soft' means that the structure can be stretched and adjusted to adapt to heat exchange tubes with different widths, and 'not soft' means that the purpose of supporting is achieved after the structure is stretched to adapt to the length of the heat exchange tubes).

Description

technical field [0001] The invention belongs to the technical field of a temperature-sensing probe fixing structure, and specifically refers to a temperature-sensing probe fixing structure for a heat exchanger. Background technique [0002] When the condenser and evaporator are in use, it is necessary to install a temperature-sensing probe on the heat-exchanging tube to detect the temperature of the heat-exchanging tube through the temperature-sensing probe. Welding and fixing on the heat exchange tube, and then installing the temperature sensing probe on the fixing frame, this method has the following disadvantages: 1. It is easy to weld the heat exchange tube when fixing the frame during welding; 2. The fixing frame is easy to miss welding , if there is a missing welding during production, and the condenser or evaporator is filled with refrigerant, if the fixing frame is repaired at this time, if the heat exchange tube is accidentally welded through, there is a hidden dang...

Problems solved by technology

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a temperature sensing probe fixing structure for heat exchangers, which effectively solves the problem that the temperature sensing probes currently on the market are fixed on the heat exchange tubes by welding. The problem that the heat exchange tube is easy to be welded and broken and the stress concentration at the welding position is prone to breakage. The traditional fixing method is changed from welding and fixing the temperature sensor on the heat exchange tube to separate from the heat exchange tube, completely avoiding the problem of welding. At the same time, using the physical state conversion principle of the object, the liquid glue in the soft support capsule is transformed into a solid state, which overcomes the contradiction of "soft but not soft" (soft means that it can be stretched and adjusted to adapt) The heat exchange tubes of different widths are not soft, that is, they are stretched to fit the length of the heat exchange tubes for the purpose of support); further, the dry ice is sublimated and sprayed on the solid glue through the principle of dry ice cleaning "energy transfer" to achieve rapid Heat transfer, so that the solid glue can be transformed into a liquid state again, so as to achieve the purpose of "softness", and then realize the reuse
