Detailed Description
The present invention will be further described with reference to the accompanying drawings. A heat exchanger based on infrared lamp tube heating, its characterized in that: the heating device comprises a cylindrical shell 1, wherein connecting plates 2 are covered on the upper end part and the lower end part of the cylindrical shell 1, the cylindrical shell 1 is arranged in a hollow manner, the cylindrical shell 1 and the connecting plates 2 are connected and encircled to form a heating cavity 3, a heating device is embedded in the heating cavity 3, cold water enters the heating cavity 3 from a water inlet pipe 4, is heated into hot water by the heating device and then is discharged from a water outlet pipe 5; the heating device comprises a plurality of heating pipes 6 which are vertically fixed on the connecting plate 2, inner holes of the heating pipes 6 are sealed relative to the heating cavity 3, and a plurality of infrared lamp tubes 7 are installed in the heating pipes 6.
The connecting plate 2 is externally provided with a cover plate 8, the cover plate 8 is provided with a fixing hole 81 corresponding to the end surface of the heating pipe 6, and two ends of the infrared lamp tube 7 are fixed in the fixing hole 81 of the cover plate 8.
The cover plate 8 is made of high-temperature-resistant insulating materials.
The infrared lamp tube 7 is replaced by a resistance heating rod, and the outer wall of the resistance heating rod is in close contact connection with the inner wall of the heating tube 6.
The cylindrical shell 1, the connecting plate 2 and the heating pipe 6 are made of stainless steel materials.
The working principle is as follows: the heat exchanger comprises a tubular shell, the upper end and the lower end of the tubular shell are covered with connecting plates, the tubular shell is arranged in a hollow mode, the tubular shell and the connecting plates are connected to form a heating cavity in a surrounding mode, and a heating device is embedded into the heating cavity.
It should be noted that: the heating device comprises a plurality of heating pipes which are vertically fixed on the connecting plate, and the inner holes of the heating pipes are relatively sealed with the heating cavity. In order to protect the infrared ray lamp better, the infrared ray lamp is installed in the heating tube. When cold water enters the heating cavity from the water inlet pipe, the water contacts the outer surface of the heating pipe, and the water is not directly contacted with the heating element for heating in the prior art. The infrared lamp tube is electrified to generate heat, and the heat is transferred into cold water through the heating tube, so that the cold water is heated and finally discharged through the water outlet pipe to be used by a user. The infrared heating pipe is thought the heating pipe heat transfer through thermal radiation's mode, no longer is traditional resistance heating and relies on the heat-conduction when contacting, consequently, infrared heating pipe not with heating pipe direct contact, can effectively protect infrared heating pipe not corroded by external world, simultaneously, has also avoided accidents such as electric leakage to appear easily in traditional contact heating.
