Abstract
The utility model discloses a cooling board. The cooling board comprises a cooling board body, a cooling water inlet tube and a cooling water outlet tube. Grooves with arc-shaped sections are distributed in the surface of one side of the cooling board body, and the cooling board body is tightly combined with heat exchange tubes. According to the section shape, each heat exchange tube is composed of a circular ring and a flat board, and the outer surface of each flat board is flush with the surface of the cooling board body. Spiral grooves are formed in the hole walls of the heat exchange tubes. The cooling board has the significant advantages of being high in heat exchange efficiency, simple in structure and good in manufacturability.
Description
Technical field:
The utility model relates to a kind of heat transfer technology, particularly a kind of coldplate.
Background technology:
Coldplate is usually used in the occasion of heating electric device, electrical appliance kit, distribution box, and the flat closed structure of the many employings of traditional coldplate arranges radiating fin in plate body cavity, and the heat exchange efficiency of this coldplate is lower.
Summary of the invention:
The purpose of this utility model is to provide a kind of coldplate that a kind of heat exchange efficiency is high.
The technical scheme that realizes the utility model object is, a kind of coldplate, comprise coldplate and turnover cooling water pipe, it is characterized in that: on a side surface of described coldplate, be distributed with groove and the heat exchanger tube that cross section is arc and combine closely, the cross sectional shape of described heat exchanger tube is annulus and a dull and stereotyped composition, and this dull and stereotyped outer surface is equal with the surface of described coldplate.On the hole wall of described heat exchanger tube, be provided with helicla flute.
The utility model has the remarkable advantage of heat exchange efficiency high and simple in structure and good manufacturability compared with the prior art.
Brief description of the drawings:
Fig. 1 is front view of the present utility model; Fig. 2 is the A-A cutaway view of Fig. 1; Fig. 3 is the top view of Fig. 1; Fig. 4 is the partial enlarged drawing of Fig. 2.
Detailed description of the invention:
In conjunction with following embodiment, the utility model is elaborated, on a side surface of coldplate 2, be distributed with horizontal deep-slotted chip breaker, the arc diameter of this deep-slotted chip breaker is greater than the diameter of heat exchanger tube 3, described heat exchanger tube 3 can be U-shaped pipe, while adopting U-shaped pipe, between the centre distance of the adjacent deep-slotted chip breaker on coldplate and the pipe of U-shaped pipe, centre distance equates, and the tube pitch of two U-shaped pipes can be less than the tube pitch between U-shaped pipe.The manufacture craft of above-mentioned coldplate, first on a side surface of cooling tube, adopt pulling eye or bore process to make deep-slotted chip breaker, choosing of the arc diameter of this deep-slotted chip breaker need meet following condition, after in the deep-slotted chip breaker of U-shaped pipe (or straight tube) insertion coldplate, coldplate is placed on the platform of press device, by press device, the body protruding from outside arc-shaped slot is compressed into notch, make the plane of pipe equal with cold plate surface, ensure that this surface contacts well with high temp objects.By the distortion of body, the cell wall of heat exchanger tube and coldplate deep-slotted chip breaker is fitted tightly, determine the distance of the diameter of deep-slotted chip breaker and the distance of center circle coldplate notch surface of groove with this.If adopted in the body of coldplate, pore is set, in heat exchanger tube is through hole after, adopt expanding joint process pipe and the hole wall of coldplate fitted tightly, the heat transfer effect of this structure is also good.But the simple efficiency of the former technique is high, it is low to consume energy.In order further to improve heat exchange efficiency, adopt pore wall to be provided with helicla flute.This helical groove heat exchange pipe is applicable to the former, can make the helicla flute on hole wall destroyed in the latter's expanded joint.Heat-transfer pipe adopts U-shaped tubular construction, and the import of each U-shaped pipe is connected with water inlet pipe 1 and outlet pipe 4 respectively with outlet, and each U-shaped pipe also can adopt series arrangement.
Claims (2)
1. a coldplate, comprise coldplate and turnover cooling water pipe, it is characterized in that: on a side surface of described coldplate, be distributed with groove and the heat exchanger tube that cross section is arc and combine closely, the cross sectional shape of described heat exchanger tube is annulus and a dull and stereotyped composition, and this dull and stereotyped outer surface is equal with the surface of described coldplate.
2. a kind of coldplate as claimed in claim 1, is characterized in that: on the hole wall of described heat exchanger tube, be provided with helicla flute.
