Description

Heat exchanger used for cooling and heating pads {HEAT EXCHANGING DEVICE USED IN COOLING AND WARMING PAD}

The present invention relates to a heat exchanger device, and more particularly to a liquid provided by the heat exchanger device in order to change the temperature of the surface of the cooling and warming pads into the cooling and warming pads, and then to the cooling and warming pads. A heat exchange device coupled to a heating pad.

Recently, as the concept of environmental protection has become more and more popular, "energy saving and carbon reduction" has become one of the important problems of our lives, and related products are constantly being introduced to the market. From ordinary power saving lamps to essential water saving devices for bathtub equipment (eg bathrooms), energy savings and carbon reduction have clearly changed our market development and our consumption trends. In various household necessities, air conditioners consume a lot of power and use environmentally unfriendly refrigerants, and thus air conditioners are one of the main targets for improvement by related manufacturers.

Since we had to turn on the air conditioner for a long time while we were sleeping to lower the room temperature, the manufacturer designed a cooling and heating pad containing a certain volume of water. The specific heat of the water is relatively large, and the water temperature does not change easily by the air temperature, so when the user is on the cooling and heating pad, the user may feel cool and dissipate the user's body heat without turning on the air conditioner. Some other manufacturers have further developed heat exchangers to improve the performance of the cooling and heating pads, which allow the liquid in the cooling and heating pads to circulate continuously between the heat exchanger and the cooling and heating pads. Is coupled to In the process of circulating the liquid through the heat exchanger, the heat exchanger absorbs heat from the liquid by the refrigerant, so that the liquid flowing into the cooling and heating pad is always kept at a low temperature, thereby improving the cooling degree of the cooling and heating pad. have.

However, the use of heat exchangers and cooling and heating pads still has many disadvantages, as described below.

(1) Environmental protection problem: Since the heat exchanger uses a refrigerant to cool the liquid through the heat exchanger, the heat exchanger is equivalent to a small air conditioner that does not conform to the original spirit and concept of encouraging environmental protection; It is not a perfect means to improve the performance of the heating pad.

(2) High power consumption: After the heat exchanger cools the liquid by the refrigerant, the compressor needs to compress the refrigerant to restore its low temperature state for repeated use, and the compressor will consume a lot of power. Accordingly, such heat exchangers are not a perfect means to improve the performance of cooling and warming pads.

(3) Prominent operating noise: According to the operating principle of the heat exchanger, a compressor is used to cool the refrigerant, and a pump is used to transfer the cooled liquid to the cooling and heating pads, so that the operation process of the heat exchanger produces a considerable noise. In addition to creating the pump, the pump also generates vibrations, and both noise and vibration undermine the quality of user rest.

(4) Large Space Occupancy: From the above description, the heat exchanger has a volume for accommodating the compressor and the pump, and occupies a lot of space, so that the user cannot place the heat exchanger in any position with the cooling and heating pads, and the cooling And flexible use of heating pads.

(5) Complex structure: Current conventional cooling and warming pads contain many tubes for circulating liquid, so the structure of cooling and warming pads is too complicated and undesirable for automated manufacturing. In addition, cooling and warming pads with excessively thick thicknesses require large space for transportation and storage and are more expensive.

In view of the foregoing, the problem of the heat exchanger is mainly due to the use of the compressor and the refrigerant, so that the heat exchanger can cool the liquid without the compressor and the refrigerant, the heat exchanger is quiet, power saving and environmentally friendly Designing a heat exchange device to operate in a phosphorus state is an important task of the present invention.

In view of the aforementioned disadvantages of conventional heat exchangers that generate noise and vibrations during operation, the inventors of the present invention have conducted extensive research and experiments based on many years of experience in the relevant industry, and eventually the cooling and Heat exchangers have been designed and developed that are used in heating pads and overcome the problems of conventional heat exchangers.

And return from the water outlet of the warming pad into the water tank to form a heat exchange circulation loop. As an alternative, the heating element is activated to heat the liquid of the heat exchange element by convection. Since the heat exchanger does not use any refrigerants and compressors to lower the temperature of the liquid, the manufacturing cost can be significantly reduced, and the heat exchanger can be manufactured lighter, thinner, shorter and smaller, as well as in electrical power. Savings and carbon reduction effects are achieved. In addition, the cushioning element absorbs the vibration force generated during the operation of the pump, so that when the heat exchanger device is operated, the maximum power saving state and the quiet effect can be achieved to improve the quality of service of the heat exchanger device.
