[0014] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described below are only used to explain the present utility model. In these descriptions, the keywords that need to be noted include "flow channel", "U-shaped", "S-shaped", "large bump", "small bump", "inverted frustum of a cone" and "bottom of the platform", etc. These are only for the convenience of describing the present utility model and simplifying the description, and thus should not be construed as a limitation to the present utility model.

[0015] As Figure 1 shown, the plate-type heating device of the present utility model includes a metal plate 1, a copper foil 2, a heating plate 3, a water inlet pipe 4 and a water outlet pipe 5. The metal plate 1 and the heating plate 3 are made of stainless steel plate materials. Refer to Figure 3 and Figure 4 shown, the heating plate 3 is fixed together by a bottom plate 34 and a flow channel plate 35 to form a flow channel 31. As Figure 2 shown, the flow channel 31 arranged on the upper part (surface) of the heating plate 3 has a U-shaped trend like an inverted and upright capital English letter, with the head and tail connected, and is partially S-shaped. As Figure 3 and Figure 4 shown, the outer contour of the main body of the flow channel 31 and the cross-section of its cavity are trapezoidal. On the upper flow channel plate 35, along the trend of the flow channel 31, large bumps 32 and small bumps 33 are provided for the cavity of the flow channel 31 to locally block the flow channel 31. The large bumps 32 and the small bumps 33 are both in the shape of an inverted frustum of a cone and protrude into the cavity of the flow channel 31 respectively. The bottom 321 of the large bump 32 is fixedly connected to the bottom plate 31 to reinforce and support the flow channel plate 35. The copper foil 2 is inserted between the metal plate 1 and the heating plate 3, and the three are in close contact and fixed together by brazing. One end of the water inlet pipe 4 and the water outlet pipe 5 is respectively communicated with the head and tail ends of the flow channel, and the other end forms a water inlet and a water outlet through a joint and is respectively connected to a water circulation heating device; alternatively, the water inlet is connected to hot water, and the water outlet is connected to a container for the remaining water after heat exchange.

[0016] When the utility model is in use, start the water circulation heating device. Hot water enters from the water inlet pipe 4 and flows along the flow channel 31 towards the water outlet pipe 5. The trapezoidal flow channel 31 has a wide flow channel width, which also increases the direct heat dissipation and heat exchange surface. The large bumps 32 and small bumps 31 have the effect of forcing water turbulence, thereby enhancing the heat dissipation effect. Since the flow channel is relatively high and wide, if there is no large bump in the middle to contact and support the bottom plate, the pressure-bearing capacity will be greatly reduced.

[0017] The above is only one implementation manner of the present utility model. For those skilled in the art, the present utility model may also have various other implementation manners with changes and modifications, which will not be elaborated one by one here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model are all included within the protection scope required by the present utility model.
