Abstract
The utility model discloses an improved liquid heat exchanger of an electronic temperature box, which comprises a heat conduction board, a refrigeration film, a base plate and a liquid clamp, wherein the base plate, the refrigeration film and the heat conduction plate are sequentially overlapped and connected through a fastener, one side surface of the base plate is in glued joint with a step in a liquid inner cavity through seal gum, a groove is arranged on the other side surface of the base plate, one surface of the refrigeration film is a hot end surface, the other surface of the refrigeration film is a cold end surface, the hot end surface coated with heat conduction silicone grease is closely clung in the groove of the base plate, and the cold end surface coated with heat conduction silicone grease is fitted with a convex surface of the heat conduction plate. Due to the increase of the base plate and the volume of the liquid clamp, the stressed area and the heat-exchange area of the refrigeration film are increased, and when the liquid heat exchanger is installed, the problems of fracture of the refrigeration film and liquid leakage of the liquid clamp can not be caused.
Description
Technical field
The utility model relates to heat-exchange device, particularly a kind of improved electronics cold and warm box liquid heat exchanger.
Background technology
Original electronics cold and warm box liquid heat exchanger is made up of heat-conducting plate, cooling piece, liquid folder sealing ring and liquid folder, and when liquid heat exchanger was installed, the cold junction face of cooling piece was close to heat-conducting plate; The hot junction face of cooling piece embeds in the liquid folder that liquid folder sealing ring is housed, and through bolt liquid folder and heat-conducting plate is fixed, because the liquid folder is little with the cooling piece contact area; The suffered pressure of hot junction face of cooling piece is big, and when using bolt, both sides receive force unbalance; Liquid folder sealing ring leaks to cause cooling piece to break perhaps; Slip is high, and high because of quality of fit during assembling, makes the fitting operation difficulty.
Summary of the invention
It is steady that the purpose of the utility model provides a kind of installation, and can prevent that cooling piece from breaking and liquid presss from both sides the electronics cold and warm box liquid heat exchanger that leaks.
For realizing above-mentioned purpose; The utility model technical scheme is: a kind of improved electronics cold and warm box liquid heat exchanger, comprise heat-conducting plate, cooling piece, backing plate and liquid folder, and liquid folder, backing plate, cooling piece and heat-conducting plate superpose successively and are connected through securing member; Wherein glued joint through fluid sealant at the step place in backing plate one side and the liquid folder chamber; The backing plate another side is provided with groove, and cooling piece simultaneously is the hot junction face, and another side is the cold junction face; The hot junction face that scribbles heat-conducting silicone grease is close in the groove of backing plate, scribbles the cold junction face of heat-conducting silicone grease and the convex surface of heat-conducting plate and fits.
One side of said liquid folder is provided with feed tube and drain pipe.
Said cooling piece is a semiconductor chilling plate.
The beneficial effect of the utility model is: owing to increased backing plate and to have strengthened the liquid clamp long-pending, the cooling piece lifting surface area strengthens with heat exchange area, when liquid heat exchanger is installed, can not take place that cooling piece breaks and liquid presss from both sides the liquid leakage phenomenon; Backing plate and liquid press from both sides with easy for installation behind fluid sealant sealing formation one closed cavity, and efficient is high.

Fig. 2 is the structural representation of liquid folder 4 among Fig. 1.
Among the figure: 1, heat-conducting plate, 2, cooling piece, 201, the hot junction face, 202, the cold junction face, 3, backing plate, 4, the liquid folder, 401, feed tube, 402, drain pipe.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further set forth, referring to Fig. 1 and Fig. 2, a kind of improved electronics cold and warm box liquid heat exchanger; Comprise heat-conducting plate 1, cooling piece 2, backing plate 3 and liquid folder 4; Liquid folder 4, backing plate 3, cooling piece 2 superposes with heat-conducting plate 1 successively and is connected through securing member, and wherein backing plate 3 one sides and liquid press from both sides that the step place passes through the fluid sealant splicing in 4 chambeies, and backing plate 3 another sides are provided with groove; Cooling piece 2 one sides are hot junction face 201; Another side is a cold junction face 202, and the hot junction face 201 that scribbles heat-conducting silicone grease is close in the groove of backing plate 3, and the cold junction face 202 that scribbles heat-conducting silicone grease is fitted with the convex surface of heat-conducting plate 1.
One side of said liquid folder 4 is provided with feed tube 401 and drain pipe 402.
Said cooling piece 2 is a semiconductor chilling plate.
Embodiment: a kind of improved electronics cold and warm box liquid heat exchanger, comprise heat-conducting plate 1, cooling piece 2, backing plate 3 and liquid folder 4, its liquid folder 4, backing plate 3, cooling piece 2 superposes with heat-conducting plate 1 successively and be fixedly connected through screw, and cooling piece 2 is a semiconductor chilling plate; Heat-conducting plate 1, backing plate 3 and liquid folder 4 all adopt aluminum alloy materials to make; Heat-conducting plate 1 is provided with a plane boss, and its area is slightly larger than cooling piece 2, and backing plate 3 is a groove-like.Cooling piece 2 is a semiconductor chilling plate; It simultaneously is a hot junction face 201, and another side is a cold junction face 202, and the cold junction face 202 of cooling piece 2 is fitted with the convex surface of heat-conducting plate 1; Binding face also scribbles heat-conducting silicone grease; Hot junction face 201 scribbles in the groove that heat-conducting silicone grease is mounted on backing plate 3, and gluedd joint through fluid sealant at the step place around backing plate 3 one sides and liquid pressed from both sides in 4 chambeies, and liquid presss from both sides and is provided with some drain sheets in 4 chambeies; One side of liquid folder 4 is equipped with feed tube 401 and drain pipe 402, is used for the liquid input and output in the liquid folder 4.
The utility model is owing to increased backing plate 3 and strengthened liquid and press from both sides 4 volumes, and cooling piece 2 lifting surface areas strengthen with heat exchange area, therefore when this interchanger is installed, can not take place that cooling piece 2 breaks and liquid presss from both sides the phenomenon of 4 liquid leakage.
