Benefits of technology

[0009] Embodiments of the present invention provide a heater unit which is constructed separately from equipment to be heated and which uses a temperature distribution equalizing means having an extremely simplified construction.

Problems solved by technology

There are many cases where it is difficult for all electronic components ranging from their housings to constituent electronic components to satisfy required temperature specifications.
(1) Since the heaters are disposed in the dispersed fashion together with the heating targets within the housing, the construction of the housing becomes complex, and this interrupts the standardization of equipment and constitutes a main cause for cost increase.
Furthermore, the fan unit needs to be provided within the housing to equalize the temperature therein, which constitutes another main cause for cost increase.

Embodiment Construction

[0027] Hereinafter, the invention will be described in detail by reference to the accompanying drawings. FIG. 1 is a front view showing an embodiment of equipment on which a heater unit of the invention is mounted.

[0028] In FIG. 1, reference numeral 1 denotes rack-mounted equipment to be heated. Reference numeral 2 denotes a similarly rack mounted heater housing, which is disposed on a bottom portion of the equipment 1 in such a manner as to firmly stick thereto. Reference numeral 3 denotes a buffer space portion, which is formed between the bottom portion of the equipment 1 and an upper portion of the heater housing 2 to equalize heat generated in the heater housing 2. Reference numeral 4 denotes heating modules, which are disposed in a dispersed fashion within the heater housing 2 with a predetermined density.

[0029]FIG. 2 is a perspective view showing an external appearance of the heater housing 2. Vent holes 22 are formed continuously in an upper side panel 21. Although not sho...

Abstract

A heater unit for heating equipment is provided which includes: a heater housing disposed on a bottom portion of the equipment in such a manner as to firmly stick thereto and having a heat source; a buffer space portion formed between the bottom portion of the equipment and an upper portion of the heater housing for equalizing heat generated in the heater housing; and a plurality of heating modules disposed in a dispersed fashion within the heater housing.

Description

TECHNICAL FIELD [0001] The present disclosure relates to a heater unit for heating equipment. RELATED ART [0002] In association with the advent of multi-function control equipment, while control equipment has found various applications other than conventional ones, places where such control unit is placed are now diversified as control targets are dispersed over a wide area. In association with this trend, the number of cases is increasing where the control unit is places in sites where conditions are severe. As an example of such cases, there can be raised a pipeline control in a dry region where the temperature changes drastically within a day or a high-latitude region where it is extremely cold. [0003] There are many cases where it is difficult for all electronic components ranging from their housings to constituent electronic components to satisfy required temperature specifications. In such cases, a method has been adopted in which a heater for heating the whole of the interior...
