DETAILED DESCRIPTION

[0019] The following descriptions of the embodiments are made with reference to the attached drawings to illustrate specific embodiments in which the present invention may be implemented. Directional terms, such as top, bottom, front, back, left, right, inside, outside, side, etc., mentioned in the present invention are only used with reference to the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, but are not used to limit the present invention. In the drawings, units with similar structures are represented by the same reference numerals.

[0020] The following further describes the specific implementation modes of the present invention in conjunction with the accompanying drawings to make the technical solutions and beneficial effects of the present invention clearer and more specific.

[0021] See attached Figures 1 to 5 The utility model includes a first liquid pump 1, a heat conduction tank 2 and a plate heat exchanger 3, characterized in that: an upper joint 201 is provided at the top center of the heat conduction tank 2, and a lower joint 202 is provided at the bottom center, a first supplementary interface 203, a second supplementary interface 204 and a plurality of mounting flanges 205 are provided on the outer side of the upper joint 201, and a release port 206 is provided on the outer side of the lower joint 202;

[0022] The heat-conducting tank 2 is provided with a plurality of electric heaters 4 matched with the mounting flange 205, and the outer side of the electric heater 4 is surrounded by a heat-conducting coil 5, and the top end of the heat-conducting coil 5 is connected to an upper concentrator 501, and the bottom end is connected to a lower concentrator 502, the upper concentrator 501 is sealedly connected to the upper joint 201, and the lower concentrator 502 is sealedly connected to the lower joint 202;

[0023] The first supplementary interface 203 is connected to one of the heat-conducting coils 5 , and the second supplementary interface 204 is connected to the release port 206 through the inner cavity of the heat-conducting tank 2 .

[0024] Furthermore, there are a plurality of heat-conducting tanks 2 , and the first liquid pump 1 is connected to the heat-conducting tanks 2 via a first manifold 6 . The first manifold 6 is provided with a plurality of first branch interfaces 601 that match the lower joints 202 .

[0025] Furthermore, the heat-conducting tank 2 and the plate heat exchanger 3 are connected via a second manifold 7 , and the second manifold 7 is provided with a plurality of second branch interfaces 701 matched with the upper joint 201 .

[0026] Furthermore, it also includes a second liquid pump 8, which is connected to the heating port 301 of the plate heat exchanger 3 through a first connecting pipe 9. The second liquid pump 8 transports the low-temperature heated liquid to the plate heat exchanger 3 through the first connecting pipe for heat exchange, thereby heating the low-temperature heated liquid into a high-temperature heated liquid.

[0027] Furthermore, a first heat-conducting liquid (not shown in the figure) is provided in the heat-conducting tank 2 , and the first heat-conducting liquid is oil with high thermal conductivity and no electrical conductivity, and the electric heater 4 directly heats the first heat-conducting liquid.

[0028] Furthermore, a second heat transfer liquid (not shown in the figure) is provided in the heat transfer coil 5 . The second heat transfer liquid is oil with high thermal conductivity and non-conductive property. The second heat transfer liquid is indirectly heated by the first heat transfer liquid through the heat transfer coil 5 .

[0029] When in use, the electric heater 4 directly heats the first heat transfer liquid, which then transfers the heat to the second heat transfer liquid in the heat transfer coil 5. The heated high-temperature second heat transfer liquid is transported to the plate heat exchanger 3 through the first liquid pump 1 and the second connecting pipe 10, and the low-temperature liquid transported by the second liquid pump 8 is heated by the plate heat exchanger 3. The cooled second heat transfer liquid flows back to the heat transfer coil 5 through the second manifold 7 to continue absorbing heat.

[0030] Since the second heat transfer liquid in the heat transfer coil 5 is heated indirectly, the second heat transfer liquid will not be overheated and deteriorate or scaled, thereby fundamentally avoiding the problem of blockage of the first liquid pump 1, the plate heat exchanger 3, the first manifold 6 and the second manifold 7, thereby increasing the service life of the equipment.

[0031] The second replenishing interface 204 is used to add and replenish the first heat transfer liquid to the heat transfer tank 2, and the release port 206 is used to release the first heat transfer liquid in the heat transfer tank 2. The first replenishing interface is used to add and replenish the second heat transfer liquid. Since the second heat transfer liquid is heated indirectly, it will not deteriorate, scale, volatilize, or clog due to high temperature, and can be used for a longer time.

[0032] The first heat transfer liquid and the second heat transfer liquid are highly heat-conductive and non-conductive oils. The inventor uses liquid silicone oil, heat transfer oil and heat-assisting liquid. The use of these highly heat-conductive and non-conductive liquids can ensure good thermal conductivity and will not conduct electricity, thereby fundamentally avoiding the risk of electric shock when using heated liquids. The heated liquid used by the inventor is liquid water. The plate heat exchanger 3 used has a built-in double flow channel consisting of a heating chamber and a heat transfer chamber. The heating chamber is equipped with two heating ports 301 with one inlet and one outlet, and the heat transfer chamber is equipped with two heat transfer ports 302 with one inlet and one outlet. The second heat transfer liquid flows through the heat transfer chamber to transfer heat, and the heated liquid is evenly heated in the heating chamber. The heat transfer tank 2 cooperates with the first liquid pump 1, the plate heat exchanger 3, the first manifold 6, the heat transfer coil 5 and the second manifold 7 to form a perfect closed loop of return indirect heating. The whole set of equipment has high heating efficiency, low failure rate, and is very energy-saving and environmentally friendly. If necessary, a heat-conducting tank 2 may be covered with a heat-insulating layer to avoid heat waste and further improve thermal efficiency.
