It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase Mutually combination.1-6 and it is described in detail the application in conjunction with the embodiments below with reference to the accompanying drawings.

Fig. 1 is a kind of schematic perspective view of duct type liquid cooling plate provided by the embodiments of the present application, and Fig. 2-5 is duct type Each projection view of liquid cooling plate, Fig. 6 are the structural schematic diagram of heating chamber.As seen from the figure, duct type liquid cooling plate includes substrate 1 and sets The pipeline 2 on 1 surface of substrate is set, pipeline 2 is bent setting on substrate, and the both ends of pipeline 2 are provided with liquid in-out mouth 3, in curved The pipeline 2 of song setting has the duct section that is parallel to each other of multiple groups, is provided between two adjacent duct sections and adds for fixing PTC The heating chamber 4 of hot device.

Duct type liquid cooling plate provided by the above embodiment can be well by ptc heater in conjunction with pure water cold plate, heating chamber The heat that interior ptc heater generates is directly transferred to the pipeline on liquid cooling plate, and the thermal efficiency is very high, overcomes liquid cooling plate and there was only list The problem of one cooling performance, realizes the cooling effect being integrated with heating function, and saves external heat management system Cost.Different media can also be passed in the product pipeline, is both able to achieve self-heating, be also used as cooling conducting part Part.

Inlet and outlet of the liquid in-out mouth 3 as liquid medium, quantity at least two, one of them is for entering medium Inlet 301, one for being discharged the liquid outlet 302 of medium, in the specific use process, inlet 301 and liquid outlet 302 Selected and setting quantity selected according to specific needs.

In some embodiments, as shown in fig. 6, heating chamber 4 includes the vertical plate 401 of two parallel face settings, two vertical plates 401 one end is connected by connecting plate 402, and the other end of two vertical plates 401 is formed with opening, openings snap-fit on substrate 1, I.e. the cross section of heating chamber 4 is half frame-type, fastens and surrounds to form full mount structure with substrate 1 afterwards on substrate 1, PTC heating Device can be fixed in full mount structure.Wherein, heating chamber 4 as shown in FIG. 6 can produce reverse back bullet when being squeezed Stress can be such that the ptc heater being mounted in heating chamber 4 fits closely with substrate 1.

In some embodiments, pipeline 2 is cylindric, and pipeline 2 is fixed on substrate 1 by u-bracket 5, u-bracket 5 1 surface of substrate and its opening are welded on away from substrate 1, pipeline 2 is fixed on inside u-bracket 5.U-bracket 5 realizes pipeline 2 It is connect with the temperature of substrate 1, assembling and welding in process etc. is facilitated to operate.

It should be noted that in above-described embodiment different coolings can be passed through with working environment according to specific needs in pipeline 2 Medium is used as cooling structure in different field.In order to obtain more sufficient heat exchange effect, pipeline 2 is preferably designed for curved Bent structure comprising but it is not limited to U-shaped, annular, snakelike and above-mentioned each shape any combination.

In some embodiments, substrate includes being oppositely arranged inlet 301 and out liquid first at 101 and second 102 Mouth 301 is arranged at substrate 1 close to the side on the first side 101.The same of substrate can be arranged in liquid in-out mouth 3 by such setting Side, the convenient connection with exterior line, saves installation space.

In some embodiments, the pipeline 2 being connect with inlet 301 by first while 101 bending extend to second while 102 shapes At inlet tube 201, pipeline 2 101 forms liquid back pipe 202 when 102 bendings extend to first by second again, liquid back pipe 202 with out Liquid mouth 302 is connected to.Medium in inlet tube 201 and liquid back pipe 202 is usually to have larger temperature difference, pipeline 2 it is such past Multiple setting can make the temperature on substrate 1 more uniform, and inlet tube 301 and liquid back pipe 302 are distributed in the entire of substrate 1 Homogeneouslly-radiating is realized on surface.

Preferably, heating chamber 4 is arranged between inlet tube 201.When needing liquid cooling plate structure to extraneous offer energy, just The medium temperature having just enter into inlet tube 201 be often it is minimum, need to heat it input energy, can mention as far as possible in this way The utilization efficiency of high-energy.

It certainly, is the input quantity for improving energy, it can also be between liquid back pipe 202 or inlet tube 201 and liquid back pipe Heating chamber 4 is set between 202, and most preferred scheme is between inlet tube 201, between liquid back pipe 202 and inlet tube It is respectively provided with heating chamber 4 between 201 and liquid back pipe 202, can be pacified in the heating chamber of different location according to specific demand in this way Dress does not install PTC heating chamber, is more favorable for adjusting.

As shown, liquid cooling plate is fixed for convenience, the first of substrate 1 102 is thickeied at 101 and second Processing, and offer multiple fixation holes.

It should be noted that can be distributed in liquid cooling plate provided herein for fixing the heating chamber 4 of ptc heater The different location of liquid cooling plate, and it is arranged quantity and is not specifically limited, and can specifically be set according to actual needs.It is preferred that , as shown in the utility model attached drawing, the quantity of heating chamber 4 is set as 2, and the symmetric position of the two sides of substrate 1 is arranged in On, above-mentioned set-up mode can make ptc heater fixed in the heating chamber 4 of two side position of liquid cooling plate equal from two sides to centre Even heat dissipation.Certainly, the quantity of heating chamber 4 may be arranged as 1 or more, can be distributed in the different location of substrate 1, example If it can be set to 1 and the middle position of substrate 1 is arranged in, make it through intermediate to two sides Homogeneouslly-radiating.

In some embodiments, heating chamber 4 and the material of substrate 1 are alumina-base material, and heating chamber 4 and the welding of substrate 1 connect It connects.Using aluminium material, light weight, thermal coefficient is big, is conducive to thermally conductive；Corrosion resistance is high；Good welding performance and surface Yi Chu Reason.
