A kind of Cold or hot cushion of the TaiWan, China M415634 patent therefore developed now, it is made by metal material, metal seat cushion has characteristic that is not fragile and easy cleaning, and Cold or hot cushion has a top board, a base plate, two conduits, two guide plates and a cooling chip.
Aforesaid top board and base plate combine the seat cushion housing forming tool inner space, and the interior sidewall surface in top board and base plate attaches conduit respectively, and conduit is for transmitting Cooling and Heat Source, and the outside wall surface of top board is pet sitting and lying place.Because existing conduit is cylinder, and cooling chip is dull and stereotyped structure and area own is less, therefore the conduit of cooling chip and circular tube shaped only has the linear contact lay of few area, and has the shortcomings such as conducting effect is not good.Therefore, prior art connects the guide plate of larger area in conduit place, then cooling chip is attached at the another side of guide plate, by large-area contact to reach good thermal conduction effect.
But though guide plate can increase area, formed between cooling chip and conduit and intercept, so cannot play the optimum efficiency of cooling chip, the setting of guide plate also improves the cost of manufacture of Cold or hot cushion in addition.
Utility model content
Because aforesaid prior art shortcoming, the utility model provides the pet pad of a kind of tool refrigeration hot merit energy, to reach the object avoiding using guide plate and reducing cost of manufacture.
For reaching the object of above-mentioned utility model, the technological means that the utility model adopts is the pet pad of a kind of tool refrigeration hot merit energy of design, and it comprises:
One top board, it has at least one conducting region, and this at least one conducting region projection forms in a side wall surface of top board;
At least one cooling chip, at least one conducting region that this at least one cooling chip is arranged on top board can produce heat transfer with top plate contact;
At least one radiating seat, it is connected with top board and has a thermal trough, and this thermal trough forms in the wall place of radiating seat;
At least one heat pipe, this at least one heat pipe is arranged in the thermal trough of radiating seat and also contacts with cooling chip respectively, and the surface that heat pipe contacts with cooling chip is a plane.
The utility model has the advantage of, with fixing cooling chip on conducting region cooling chip being arranged on top board, multiple radiating seat is connected below top board, each radiating seat is all provided with thermal trough, heat pipe is placed in thermal trough, because heat pipe utilizes plane to contact with cooling chip, then cooling chip can directly be fitted heat pipe, cooling chip is changeable is heat radiation or warming pattern, when for radiating mode, cooling chip is cold junction towards the one side of top board, then top board is subject to the heat absorption of cold junction and temperature declines, pet can feel nice and cool, but the another side of cooling chip is hot junction produces heat, this thermal source arrives radiating seat by the transmission of heat pipe, thermal source scatters and disappears in air by radiating seat again, otherwise be warming pattern, cooling chip is towards the one side pyrogenicity of ceiling, then the another side of cooling chip is cold junction, cold junction is heat-absorbing action, can pass through the heat in radiating seat absorption air, extra heat pipe is not used in process due to refrigeration heat, therefore the effect of its refrigeration heat is better than prior art.
