The main disadvantage is that it will cause solution droplets to enter the pipeline with the air, causing corrosion of metals and pollution of the indoor environment. Therefore, the application in demanding working environment is greatly restricted.

Therefore, there is an urgent need to design a new heat transfer device that can solve the above problems.

In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

Certain embodiments of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings, in which some but not all embodiments are shown. Indeed, various embodiments of the disclosure may be embodied in many different forms and should not be construed as limited to the embodiments set forth here; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements.

In a first exemplary embodiment of the present disclosure, a heat transfer device with adaptive control of heat transfer is provided. FIG. 1 is a schematic structural diagram of a heat transfer device for adaptive control of heat transfer according to a first embodiment of the present disclosure. Fig. 2 is a schematic diagram of the installation and application of the structure in Fig. 1 on a heat exchanger. As shown in Fig. 1 and Fig. 2, the heat transfer device for adaptive control of heat transfer in the present disclosure includes: a heat exchanger 20; a memory alloy throttling device 10 installed in the heat exchanger 20; the memory alloy throttling device 10 includes: The bracket 11 is connected to the inner wall of the heat exchanger 20; the sliding rod 12 is fixed at both ends of the heat exchanger 20 by connecting with the bracket 11; the memory alloy spring 13 is nested on the sliding rod 12, and the memory alloy spring 13 One end is connected with slide bar 12, and the fixing mode of memory alloy spring 13 here can also be that memory alloy spring 13 first end is connected with slide bar 12 and support 11 simultaneously; Throttle plug 14a, it and memory alloy spring 13 second ends connected, and the slide rod 12 passes through the central axis of the throttle plug 14a and is connected with the throttle plug 14a. In this embodiment, the throttle plug 14a is a cylindrical structure; the throttle ring 15a is nested on the slide rod 12, and The outer wall of the throttling ring 15a is in contact with the inner wall of the heat exchanger 20, and the throttling ring 15a is a cylindrical ring structure in this embodiment.

In the present disclosure, the throttle plug 14a can freely slide back and forth on the slide rod 12 when the temperature of the memory alloy spring 13 changes and causes the length to expand and contract. The length of the memory alloy spring 13 can be designed to be proportional to the deformation temperature, that is, when the temperature was higher than the deformation temperature, the length of the memory alloy spring 13 increased as the temperature increased; when the temperature was lower than the deformation temperature, the length of the memory alloy spring 13 The length decreases with decreasing temperature. If the deformation temperature of the memory alloy spring 13 is set between 16-25°C, when the air temperature after the treatment is higher than 25°C, it means that the temperature entering the room is too high, and the length of the memory alloy spring 13 becomes longer. The distance between the throttling plug 14a and the throttling ring 15a decreases, the resistance to the flow of the working fluid increases, the heat transfer decreases, and the temperature of the treated air gradually decreases. When the temperature of the treated air is lower than 16°C, it means that the temperature entering the room is too low at this time, the length of the memory alloy spring 13 becomes shorter, the distance between the throttle plug 14a and the throttle ring 15a increases, and the working medium flows The resistance decreases, the heat exchange increases, and the temperature of the treated air gradually increases. The flow rate of the working medium inside the heat exchanger 20 can be changed with the change of the temperature of the working medium, and then the heat exchange capacity of the heat exchanger 20 can be controlled to realize the self-adaptive control of the heat exchange capacity.

The heat exchanger part of the heat transfer device for adaptive control of heat transfer in this embodiment will be described in detail below.

The heat exchanger 20 is a U-shaped heat exchanger, which is used for air conditioning in air conditioning, refrigeration, dehumidification, drying and other industries. The room temperature control does not need to prepare a low-temperature cold source for dehumidification, thereby improving energy utilization and Room comfort. The heat exchanger 20 includes: an evaporator 21 installed at the first end of the heat exchanger 20, and the evaporator 21 includes several heat conduction pipelines. The condenser 22 is installed at the second end of the heat exchanger 20, and the evaporator 21 includes several heat conduction pipelines. The heat conduction pipelines of the evaporator 21 and the condenser 22 are connected with several connecting pipelines to form a non-interfering loop structure.

As shown in FIG. 1 , the hot air first passes through the evaporator 21 of the heat exchanger 20 for pre-cooling. At this time, the temperature of the hot air decreases and the relative humidity increases. The air then passes through the condenser 22 of the heat exchanger to absorb heat, the temperature increases and the relative humidity decreases. At this time, low-temperature dry air is sent into the room. During this process, the evaporator 21 of the heat exchanger 20 absorbs the heat carried in the hot air, and the working fluid in the heat exchanger 20 evaporates after absorbing the heat, and enters the condenser 22. In the condenser 22, the working fluid condenses and releases Give air, raise the temperature of the air, and lower the relative humidity.

Although the above-mentioned heat exchanger 20 can save reheat, the reheating effect will continuously heat the air entering the room along with the normal operation of the heat exchanger 20 . Since the temperature and humidity parameters of the outdoor fresh air are changing at any time, but the indoor temperature and humidity are required to be kept constant, if the return heat of the heat exchanger 20 can adapt to the working conditions of the outdoor fresh air to the greatest extent, it will greatly improve the performance of the heat exchanger. 20 performance and application range. For this reason, the present disclosure installs a memory alloy throttling device 13 on the heat exchanger 20, and adjusts the heat transfer amount of the heat exchanger 20 by controlling the flow rate of the working medium inside the heat pipe to realize self-adaptive control of the regenerative amount.

That is, when the temperature is higher than the deformation temperature, the length of the memory alloy spring 13 shortens as the temperature increases; when the temperature is lower than the deformation temperature, the length of the memory alloy spring 13 elongates as the temperature decreases. If the deformation temperature of the memory alloy spring 13 is set between 16-25°C, when the air temperature after processing is higher than 25°C, it means that the temperature entering the room is too high at this time, and the length of the memory alloy spring 13 is shortened, saving energy. The distance between the flow plug 14a and the throttling ring 15a decreases, the resistance to the flow of the working medium increases, the heat transfer decreases, and the temperature of the treated air decreases gradually. When the temperature of the treated air is lower than 16°C, it means that the temperature entering the room is too low at this time, the length of the memory alloy spring 13 is elongated, the distance between the throttle plug 14a and the throttle ring 15a is increased, and the working medium flows The resistance decreases, the heat exchange increases, and the temperature of the treated air gradually increases. The flow rate of the working medium inside the heat pipe can be changed with the change of the temperature of the working medium, and then the heat transfer capacity of the heat exchanger 20 is controlled to realize the self-adaptive control of the heat transfer rate.
