Embodiment Construction
[0008] Such as figure 1 As shown, the floating head heat exchanger includes a shell 1, inside the shell 1 there is a partition 7 and a cold water pipe 2, and the shell 1 is provided with a hot water inlet pipe 6, a hot water outlet pipe 3, a cold water inlet pipe 4 and a cold water outlet Pipe 5, the cold water inlet pipe 4 is separated from the cold water outlet pipe 5, and the cold water inlet pipe 4 is connected to the cold water pipe 2. The cold water pipe 2 is a segmented water pipe, and the two segmented water pipes communicate with each other through a closed space. One end of the pipe 2 is fixed on the housing 1, and the other end is freely supported by the housing 1. The free end of the cold water pipe 2 is the floating head 8 of the present invention, which can release the pressure freely when the cold water pipe 2 expands with heat and contracts with cold.
[0009] The heat exchanger provided by the invention has simple structure, good heat exchange effect and safe...

The invention provides a floating head heat exchanger which comprises an outer shell; the outer shell is internally provided with a baffle plate and a cold water tube; the outer shell is provided with a hot water inlet tube, a hot water outlet tube, a cold water inlet tube and a cold water outlet tube; the cold water inlet tube and the cold water outlet tube are separated from the middle; the cold water inlet tube is communicated with the cold water tube which is a sectional-type water tube; two sectional-type water tubes are communicated through an enclosed space; and one end of the cold water tube is fixed on a shell, and the other end of the cold water tube is supported freely by the shell. The floating head heat exchanger is simple in structure; because one end of the cold water tube is a free end, the free end is heated and expanded under the condition of high hot water temperature; and the expansion pressure can be released for the cold water tube in the length direction, and the cold water tube can not be damaged.
Description
technical field [0001] The invention relates to a floating head heat exchanger. technical background [0002] Existing heat exchangers, whether they are tube heat exchangers or plate-plate heat exchangers, all involve a problem, that is, when the cold water pipe expands when exposed to heat, the pressure storage of the connecting device with the cold water pipe will occur, causing the cold water pipe to Damage to the connecting device and connecting parts will reduce the service life of the heat exchanger. Contents of the invention [0003] The present invention relates to a floating head heat exchanger, which can solve the above-mentioned defects. [0004] In order to solve the above technical problems, the technical solution provided by the present invention is as follows: a floating head heat exchanger, the floating head heat exchanger includes a shell, a partition and a cold water pipe are arranged in the shell, and a hot water inlet is provided on the shell Pipe, ho...
