Problems solved by technology
[0003] Existing problems and shortcomings: These devices are generally assembled at the installation site, and professional operators need to monitor the equipment from time to time when the equipment is running
If the plate heat exchanger is used to add temperature and pressure reduction device, the investment will be increased, and part of the high-temperature condensed water will be wasted.
In addition, these devices occupy a large area and are complicated to control after assembly

Embodiment Construction
[0024] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0025] Such as figure 1 , 2 As shown, the present invention includes a heat exchange device and a control device 29 for controlling the operation of the heat exchange device. The heat exchange device is arranged on a base 1. The heat exchange device includes a shell-and-tube heat exchanger 2, a plate heat exchanger Heater 3, temperature control valve 4, circulation pump, water supply pump, valves, thermometer 9, pressure gauge 10, temperature sensor 11, pressure sensor 12, the heat medium on the primary side enters the shell-and-tube heat exchanger 2 through the temperature control valve 4 For the first heat exchange, a part of the heat is released and then enters the plate heat exchanger 3 for secondary heat exchange, and the heat is released again before being discharged; the secondary side low-temperature water enters the shell-a...

A heat exchange unit relates to a heat exchanger. A common heat exchange unit is assembled on an installation site, a professional operator needs to monitor the device constantly when the device is installed, cost is high, water is wasted, and the unit is large in occupation area and complex in control after assembly. The heat exchange unit comprises a heat exchange device and a control device used for controlling the heat exchange device to work. The heat exchange unit is characterized in that the heat exchange device is arranged on a base, the heat exchange device comprises a pipe casing type heat exchanger, a plate heat exchanger, a temperature control valve, a circulation pump, a water supplementing pump, a valve, a temperature gauge, a pressure meter, a temperature sensor and a pressure sensor. The temperature sensor is arranged on a secondary side outlet, a temperature signal of the temperature sensor is fed back to the control device, and the control device controls the temperature control valve to act. The heat exchange device is arranged on the base, onsite assembly is not required, cost is reduced by means of combination of the plate heat exchanger and the pipe casing type heat exchanger, and hot water of two different temperatures can be produced to meet different requirements.
Description
technical field [0001] The invention relates to a heat exchanger. Background technique [0002] With the development of the national economy, in the field of heating and heating, due to the increasingly high requirements for energy conservation and environmental protection, central heating has become the mainstream in systems such as community heating, domestic water, and hot water for enterprise production processes. The traditional heat exchange units for central heating mainly use steam or high-temperature hot water as the heat medium, and generally use a shell-and-tube heat exchanger (if the primary heat medium is steam and the temperature is high, a plate heat exchanger is used to install it) The desuperheater reduces the temperature of the primary heat medium to less than 150 ℃), a circulation pump, a water supply pump, valves, instruments, electric control cabinets and accessories. [0003] Existing problems and shortcomings: These devices are generally assembled at ...
