Lower the surface temperature of heat exchanger, lift the thermal efficiency, reduce a kind of U-tube heat exchanger of heat loss.
The utility model solves the technical scheme that its technical problem used：
A kind of U-tube heat exchanger, including heating wire and water pipe, it is characterised in that：The water pipe interlude is designed to U-shaped
Bringing-up section, the water pipe of more than three is along linear interval spread configuration, and the U-shaped bringing-up section on each water pipe constitutes a U-shaped and added together
Heat channel, the heating wire is set in above-mentioned U-shaped heating tank, constitute each U-shaped bringing-up section inner surface of U-shaped heating tank respectively with
The upper and lower side surface thermal contact conductance of heating wire.
A kind of U-tube heat exchanger as described above, it is characterised in that：The heating wire takes the shape of the letter U, and the two of U-shaped heating wire
End is respectively positioned on the same side of the U-shaped heating tank, and the different U-shaped heating wire of multiple length is sequentially stacked constitutes a U from inside to outside
Shape heating tube group, multiple U-shaped heating tube groups heat trench bottom from the U-shaped and are arranged side by side to U-shaped heating tank top.
A kind of U-tube heat exchanger as described above, it is characterised in that：The water pipe has ten.
A kind of U-tube heat exchanger as described above, it is characterised in that：The entrance point of each water pipe is connected with cold water
Joint, entrance point and the cold water weld of each water pipe are connected as a single entity, and cold water joint is provided with a public water inlet；Each water
The port of export of pipe is connected with hot water joint, and the port of export and the hot water weld of water pipe are connected as a single entity, and hot water joint is provided with one
Public delivery port.
A kind of U-tube heat exchanger as described above, it is characterised in that：Adjacent 2-8 millimeters of two water pipes spacing.
A kind of into or out water of U-tube heat exchanger as described above, it is characterised in that：The cold water joint and hot water connect
Certain space water storage is provided with head.
The beneficial effects of the utility model are：
1st, cold water pipe interlude is designed to U-shaped bringing-up section, and the U-shaped bringing-up section on each water pipe constitutes U-shaped heating together
Groove, heating wire is set in above-mentioned U-shaped heating tank, each U-shaped bringing-up section inner surface on U-shaped heating tank respectively with heating wire
Upper and lower side surface thermal contact conductance, so multiple water are heated simultaneously, it is to avoid need water temperature heating high temperature in water pipe in the prior art
Afterwards again with cold water mix when, it is necessary to the heat waste that Water pipe heating is caused to very high surface temperature.The technical program product is only
Need the temperature of the water temperature heating in multiple water pipes to setting, the water temperature of multiple water pipes is approached, and multiple water pipes are same
When water outlet also can guarantee that sufficiently large water yield, improved with the thermal efficiency, surface temperature is low, the small effect of heat loss.
2nd, heating wire takes the shape of the letter U, and the two ends of U-shaped heating wire are respectively positioned on the same side of U-shaped heating tank, facilitate wire to connect.
3rd, the different U-shaped heating wire of multiple length is sequentially stacked constitutes a U-shaped heating tube group from inside to outside, and multiple U-shapeds add
Heat pipe heat heats trench bottom from the U-shaped and is arranged side by side to U-shaped heating tank top, high with heater wire arrangement density, unit bodies
The high effect of the efficiency of heating surface in product, is conducive to water in quick heating pipe to design temperature.
