Description

Technical Field

[0001] The present application relates to the field of heat exchangers, and in particular to a floating coil heat exchanger. Background Art

[0002] The floating coil heat exchanger is an indirect heat exchanger. The heat transfer part uses copper tubes. The heat transfer tubes are made into spirals and float in the shell, so they are called floating coils. The floating coil heat exchanger is a typical device in the domestic hot water central heating system in recent years.

[0003] At present, floating coil heat exchangers require cranes or large transport vehicles for installation or transportation, or the floating coil heat exchangers must be disassembled for transportation, which is very cumbersome and time-consuming. Especially when the floating coil heat exchanger equipment is fixed to the designated use position, it is inconvenient to move and cannot be moved to the precise position. Utility Model Content

[0004] Based on this, it is necessary to provide a floating coil heat exchanger to solve the problem that the existing floating coil heat exchanger equipment is inconvenient to move and cannot be moved to a precise position when fixed to a designated use position.

[0005] The present application discloses a floating coil heat exchanger, comprising:

[0006] Heat exchanger;

[0007] A first clamping assembly, sleeved on one end of the heat exchanger, for clamping the heat exchanger;

[0008] a second clamping assembly, sleeved at the other end of the heat exchanger, for clamping the heat exchanger, the first clamping assembly and the second clamping assembly are arranged parallel to each other, and the first clamping assembly and the second clamping assembly have the same structure;

[0009] A support frame is arranged at the bottom of the heat exchanger, and the first clamping assembly and the second clamping assembly are both fixed on the top of the support frame;

[0010] The universal wheel assembly is slidably arranged on the support frame.

[0011] The present application relates to a floating coil heat exchanger, which clamps the two ends of the heat exchanger by a first clamping assembly and a second clamping assembly to fix the position of the heat exchanger, and then realizes the extension and retraction of the universal pulley assembly by sliding the universal pulley assembly. When the universal pulley assembly is extended, it is convenient to move the floating coil heat exchanger as a whole to an accurate position. When the universal pulley assembly is retracted, the floating coil heat exchanger as a whole falls into the accurate position and is fixed. BRIEF DESCRIPTION OF THE DRAWINGS
